When residents begin to get their homes ready for the upcoming winter season, they may find household materials that may pose a hazardous risk to the environment and public safety. The fall is a great time to get rid of these unwanted item in a safe and easy way. Unusable or unwanted chemicals are considered household hazardous waste when their disposal poses an environmental or health threat. When disposed of in the garbage, down the drain or on the ground, some household chemicals can threaten our environment, harm garbage collectors or hurt you.
Most household hazardous wastes are hazardous because they are flammable, corrosive or toxic. Characteristic words indicate the type of hazard posed by a product - flammable, corrosive or toxic. Look for the signal words on the label. Signal words - caution, warning, danger, poison - indicate the product's degree of hazard. To help protect the environment and your health, choose the least hazardous product to get the job done. For more information contact Kris Larson, Water Resource Specialist, at
Do you want to start a new garden or fill in some gaps? Fall is a great time to plant. The soil is still warm and promotes good root growth and the cooler weather and fall rainfall reduce heat stress on new plants. Select plants based on the area's soil moisture and light exposure. Blue Thumb's Plant Finder is a great tool for selecting native plants and has a list of MN native plant nurseries. Protect pollinators! - Be sure the plants you buy were not grown with systemic pesticides such as neonicotinoids, which are highly toxic to bees and other pollinators.
Choose plants to create habitat for birds and pollinators. Find bird-friendly native plants with Audubon's plant database. Select plants that flower from spring to fall to provide pollen and nectar for pollinators. Learn more about pollinator preferences and include host plants in your garden. Join ACD and help plant pollinator gardens throughout Anoka County. Learn more and sign up here. For more information contact Carrie Taylor, Restoration Ecologist, at
Since its establishment in 1988, the Environment and Natural Resources Trust Fund (ENRTF) has invested over one billion dollars in environmental projects "for the public purpose of protection, conservation, preservation, and enhancement of the state's air, water, land, fish, wildlife, and other natural resources." The constitutional dedication of these funds is set to expire in 2025, but Minnesota residents can vote this November to rededicate them through 2050. A 'Yes' vote supports this measure, whereas a 'No' vote opposes it. If left blank on the ballot, it will be counted as a 'No' vote.
Funding for the ENRTF originates from Minnesota State Lottery proceeds and is administered by the Legislative-Citizen Commission on Minnesota Resources. It is a substantial source of long-term and stable funding for a variety of organizations and projects throughout the state, supporting efforts tied to improving water quality, habitat, recreation, outreach and education, renewable energy, and more. Learn more about the ENRTF and find a full list of the 1,700(+) projects it has supported HERE. For more information contact Breanna Keith, Water Resource Specialist at
We secure lots of grants at ACD. They are a mainstay of our funding; we do not levy taxes. For our water quality projects, grants are changing significantly with a recent program called Watershed Based Implementation Funding (WBIF). These recurring grants are providing the foundation for sustained, cohesive programs rather than a start-and-stop approach.
Historically, grants were competitive. And many still are. We complete a lengthy application process and our proposals are scored against others. The grant lasts a few years and is done. This continues to work well for many of our largest, stand-alone projects. In fact, ACD has applied for a half dozen of them in just the last few months.
New WBIF funding is not competitive, not awarded to one agency, recurs every two years, and the dollars go to a watershed area. Local agencies in that watershed collaborate together to decide how to best utilize the money. The watershed must have one or more locally- and state-approved plans to guide their decisions. Instead of competing against one another, local managers are collaboratively deciding on the projects with the best return on investment.
ACD hosted a Rum River metro-watershed WBIF grant for the last three years. The grant is closing and we're pleased to report on some outcomes that included 9 Lake George shoreline stabilizations; 1 Rum Riverbank stabilization; 6 rain gardens in the City of Anoka; 1 swale stabilization in St. Francis; subwatershed studies that identify and rank projects for Ford Brook, East Twin Lake, and Pickerel Lake; a bunch of water quality public outreach, and more. Additional Rum metro WBIF funds have been received in 2022 and 2024, and work is underway.
WBIF grants are for water quality improvements that are the mutual priorities of watershed managers. ACD continues to utilize a variety of grants for other types of projects, such as pollinator plantings, easements, habitat, and more.

You can contribute to ACD's efforts to enhance habitats across Anoka County by collecting wildflower seed! You can send us a picture of the plant if you're uncertain of the ID. You can tell that seeds are ready to collect when they are dry and hardened. Milkweed plants produce large seed pods. Their seeds are ready to collect when the pods begin to brown in color and split open with gentle pressure. We prefer that seed is detached from its fluff. See an example of how to clean milkweed seed.
When collecting seed, please follow these guidelines:
Lakes provide habitat for wildlife, recreation opportunities, and natural beauty. Yet, our everyday landscaping choices can negatively impact these vital bodies of water.
Lake-friendly landscaping provides many benefits, and purposeful design can ensure you don't need to compromise access to the water or lakeside recreation opportunities.
What Is Lake-Friendly Landscaping?
Lake-friendly landscaping focuses on reducing pollution and preserving the health of our lakes. It involves making mindful choices in how we design and maintain our outdoor spaces to minimize runoff, limit chemical use, and support natural habitats.
Top Tips for Lake-Friendly Landscaping
1. Minimize Lawn Area: Lawns often need a lot of water and fertilizer, which can lead to nutrient-laden runoff. Reducing lawn space and incorporating groundcovers or mulched areas can help decrease runoff and save time on maintenance.
2. Install a Native Plant Buffer: Native plants are adapted to our local environment, requiring less water, fertilizers, and pesticides. A buffer of native grasses, flowers, shrubs, and trees can serve as a natural filter, trapping pollutants and preventing them from reaching the water. Native plant root systems also help reduce soil erosion, both along the shoreline and upslope, preventing excess nutrients from washing into lakes. If you prefer a more formal garden appearance, cluster plants of the same species throughout the area to create a planned look. Frame your lake view by planting taller species along the property boundaries and shorter species toward the center.
3. Manage Stormwater Runoff: Be intentional about where runoff from your property is routed. Directing runoff to rain gardens, permeable areas, or rain barrels will reduce the volume of runoff carrying pollutants directly to the lake.
4. Educate and Involve the Community: Spread the good news; share these practices with neighbors and participate in local conservation efforts. Community-wide adoption of lake-friendly landscaping can have a significant positive impact.

Ford Brook is a stream tributary to the Rum River draining over 24,000 acres of rural lands in northwestern Anoka County. Nutrient concentrations in Ford Brook regularly exceed state standards for impairment, thereby contributing to excess nutrient loading in the Rum River. Addressing this issue requires watershed-level analyses and an understanding of which best management practice (BMP) would provide the greatest benefit per dollar spent; ACD's Subwatershed Analysis ("SWA") approach does just this.
ACD has completed over 20 urban SWAs in order to strategically plan for BMPs such as stormwater ponds, rain gardens, and subsurface structures treating stormwater runoff. However, replicating this process in rural watersheds, dominated by agriculture, required different tools and techniques; ACD achieved this for the Ford Brook Watershed through the use of desktop analyses, targeted water quality monitoring, field surveys, and a new modeling tool called PTMApp.
As a result, over 250 candidate water quality improvement projects were sited within the Ford Brook Watershed. The majority of these are agricultural practices such as cover crops, no-till farming, grassed waterways, water and sediment control basins, and enhanced riparian buffers, but additional practices such as prescribed grazing, wetland restorations, and lakeshore stabilizations were also included. For each practice, anticipated costs and water quality benefits to Ford Brook were generated, and all findings are summarized in detail in the corresponding SWA report. This report will be a valuable asset as we pursue nutrient reduction goals in Ford Brook and, by extension, the Rum River. For more information contact Breanna Keith, Water Resource Specialist at

Cedar tree revetments are a low cost, environmentally friendly option to address eroding streambanks. Cedar revetments use Eastern red cedar trees to serve as natural armor, providing protection along eroding riverbanks. Revetments will slow or stop erosion during the project's lifespan and reduce the likelihood of a much larger and more expensive corrective project in the future. Riverbank erosion contributes sediment and other pollutants into waterways, reduces riparian habitat, and results in property loss. Stabilizing your eroding riverbank will provide water quality benefits as well as protect your property.
ACD is in the final stages of completing eight shoreline stabilization projects at Martin Lake in Linwood Township. The projects stabilize over 700 linear feet of shoreline. Each project includes a native plant buffer and many include in-lake emergent plants. These projects were funded by the landowners and a grant from the Clean Water, Land and Legacy Amendment. For more information contact, Watershed Projects Manager, Jamie Schurbon at
Approximately 1,500 feet of severely eroding riverbank in the City of Anoka's Mississippi River Community Park was stabilized in late 2021. The project included tree clearing, bank reshaping, riprap, erosion control blanket, seeding, and planting a variety of native plant species. Since installation, the site has been subjected to multiple years of high water levels. Both the riprap on the lower elevations of the bank and the vegetation on the upper elevations have successfully stabilized the site.
Sandbar willows along the top of the rock are filling in densely and provide additional bank stability, wildlife habitat, and a more natural aesthetic to the reconstructed bank. Some of the trees that were planted have struggled, likely due to the 2023 drought, and will continue to be monitored for potential supplemental plantings in the future. Vegetation maintenance is an ongoing process that helps the native species establish. One activity you may observe is mowing to a height of approximately 6" to limit weed species from dispersing seed. For more information contact Mitch Haustein, Shoreline and Stormwater Specialist, at
Golden Lake is the jewel in the crown of the City of Circle Pines. Over the decades, clear water gave way to murk and algae. A focused effort over the last several years by many local partners and residents leveraging state funds has turned the lake around; enough so that Golden Lake is being removed from the Impaired Waters List.
At 57 acres, Golden Lake is relatively small, particularly compared to the watershed that drains to it of over 6500 acres. With so much water flowing in from such a large area, Golden Lake is considered a 'flow through' lake, with the water ending up in Rice Creek. Golden Lake essentially acts like a bathtub with the faucet always turned on and a drain always open. Enough water comes in to replace all of the water three times every couple years. This is why efforts to clean up the water, started by installing projects upstream in the watershed.
Working with the City of Blaine, the Rice Creek Watershed District and $88,950 from the Clean Water Fund, Anoka Conservation District retrofitted a stormwater treatment pond in Blaine with an iron-enhanced sand filter bench installed along the perimeter. Iron holds on tight to phosphorus enabling this small project to reduce phosphorus by 11% of the goal to meet State water quality standards. Completed in 2015 at Centennial Green Park, water now filters through the iron-enhanced sand filter before entering the ditch and making its way to Golden Lake. The success of this project inspired a larger effort a bit downstream.
With a $467,970 Clean Water Fund grant, the City of Circle Pines, Rice Creek Watershed District, and Anoka Conservation District hired WSB to design and oversee installation of a pump-controlled iron-enhanced sand filter basin near an existing stormwater pond on Circle Pines-owned property adjacent to Golden Lake. Completed in 2019, water is pumped from an existing pond to two iron-enhanced sand filter beds, before it reaches an outlet to the lake.The project was designed to remove 50 pounds/year of phosphorus entering the pond from Anoka County Ditch 53-62, which carries stormwater runoff from about 6,425 acres.
"Without the Clean Water Fund, neither of these projects would have gone in the ground. Typically, the financial hurdles are often the hardest to get over, and the Clean Water Fund provides a fantastic opportunity to bridge that gap," said Mitch Haustein, Anoka Conservation District Stormwater and Shoreland Specialist.
These projects alone would not have been enough. Groups like the Friends of Golden Lake have helped to spread the word about lawn care to reduce fertilizer and chemical inputs into the lake, stabilizing eroding shorelines, installing buffer plantings, and allowing rooted weeds to grow to help suck up the phosphorus so algae doesn't. Over the past eight years, RCWD monitoring data show phosphorus levels are down 20% to 50% compared with the longtime average dating back to 1976. "The lake is as healthy as it's been in decades – thanks to the ongoing efforts by many" per the Friends of Golden Lake at www.facebook.com/friendsofgoldenlake/. Let's keep working together to keep it that way! For more information contact Chris Lord, District Manager, at

Planting native plants and nectar-rich flowers, supplying food and water sources, and avoiding pesticides are some of the keystones for attracting wildlife to your garden. Different species of pollinator prefer different shapes of flowers. Some like flat clusters of tiny flowers, and others seek out trumpet-shaped blossoms. Native plants such as coneflower, New England aster, and butterfly weed offer a variety of flower shapes to attract a variety of wildlife. Planting indigenous flowers and grasses among native trees and shrubs creates a self-sustaining environment. Plus, native plants require less maintenance than non-native species because they are better suited to the soil and climate.
Keep an eye out for invasive plants that may try to sneak into your garden. These include purple loosestrife, Japanese knotweed, crown vetch, and multiflora rose, all of which can spread rampantly. There are free apps you can download to help you identify plant species. A pond can provide refreshing drinks for wildlife and habitat for fish, frogs, and other water-loving creatures. Thoughtfully placed plants, including hardy water lilies and arrowhead in and around the water are key ingredients for a healthy ecosystem.
Bird baths are a simple way to attract wildlife, especially feathered friends who appreciate a place to safely drink and bathe.Birds prefer shallow basins no more than 2 inches deep with a rough surface for good gripping. For protection against lurking cats and other predators, place a bird bath a few feet from a tree or shrub so that the area immediately surrounding it is open yet close enough to sheltered perches for quick getaways.
While adult butterflies fly from flower to flower sipping sweet nectar, their wriggly offspring are content to feast on a single host plant. Parental instinct guides each species to lay eggs on the plants their offspring favor. Favorite caterpillar cuisine includes parsley, dill, fennel, milkweed, willow, Queen Anne's lace, spicebush, and white clover. Pesticides can cause harm to the butterflies and bees you're trying to support. If you plant a diverse mix of plants, especially natives, pests are unlikely to do much damage to your garden so it's best to accept a little imperfection just let nature take its course.
Birds such as robins, brown thrashers, and cedar waxwings flock to landscapes that feature fruit-bearing trees and shrubs. Native species that fit into yards large and small include serviceberry, crabapple, and hawthorn. Don't try to do all this at once! Pick one project this summer and add it to your yard. You'll notice the change immediately. As time goes on; you can keep modifying and make changes as you go. Enjoy! Learn more from the source article or contact Becky Wozney, Wetland Specialist, at
ACD staff, volunteers and students are collecting data to record milkweed plants, flowering plants, Monarch caterpillars and Monarch butterflies in prairies throughout Anoka County. The data will be entered into a national database, which is utilized to understand how monarchs interact with the environment, and how habitat and monarch populations change over time. The data will also be used to guide management decisions at each prairie. ACD recently applied for BWSR pollinator grant funds, which would provide funding for future habitat enhancement activities with students in the Anoka-Ramsey Community College prairie and to broadcast milkweed and other wildflower seed after Anoka County Parks prescribed prairie burns. Sign up today to volunteer with ACD or for more information contact Carrie Taylor, Restoration Ecologist, at
On lakeshores and riverbanks, fluctuating water levels, currents, or wave action can gradually eat away the soil along the water's edge and compromise the ground above. However, any slope – regardless of its proximity to a waterbody – can experience erosion from water runoff. Fortunately, there are steps you can take to mitigate these impacts.
Vegetation is often essential to slope stabilization. Native trees, shrubs, wildflowers, and grasses provide ground cover, slow the velocity of water runoff, and produce a network of deep, interconnected roots, which help lock soil in place. Lawn debris, heavy shade, and invasive buckthorn are common drivers of suppressed plant growth. To manage these challenges, avoid dumping yard waste on sloped areas, prune trees and shrubs to increase sunlight, and remove buckthorn using these techniques. Then, bolster the native plant community with supplemental seeding and/or plantings. Be sure to select species well-suited to your property, and support them as they became established by removing weeds, watering when needed, and covering temporarily exposed soils with erosion control fabric. This seed selection tool, plant finder tool, and native plant encyclopedia can help you select plants well-suited to your site.
In some cases, additional stabilization elements are needed. Rock rip-rap, coir logs, and tree revetments are commonly used to protect the zone where moving water meets the land and restricts vegetation growth. Excessively steep slopes can be re-shaped to a more stable grade, and brush or straw wattles can be trenched into the slope to slow water runoff and trap soil. Taking early action to stabilize your slope is key to avoiding costlier solutions such as retaining walls or other heavily engineered approaches.

In 2019, The Anoka Sand Plain (ASP) Rescue Program collected MN State Threatened Rotala ramosior (toothcup) seed from a site and the collected seed was taken to the MN Landscape Arboretum's seed bank for storage and preservation. The ASP Program is always on the search for suitable habitat and the Cedar Creek Ecosystem Science Reserve has habitat, active management and a willing landowner. Bison were introduced to part of the Reserve, creating open soil disturbance with their trails and wallows.
In fall, 2023, the ASP Rescue team spread a small amount of seed along and the area was recently monitored this spring and countless Rotala ramosior – toothcup plants were identified throughout the wetland depression. Toothcup is an annual whose population fluctuates due to changes in water levels along shorelines and wetland depression habitats and requires disturbance to create bare soil for the seeds to have space to germinate. The ASP Rescue team will continue to monitor this area to determine the results of the seeding, which will help guide future reintroduction and management efforts. For more information contact Carrie Taylor, Restoration Ecologist, at
ACD recently had several projects where the contractor used barges to stabilize shorelines that are otherwise be difficult to reach. It has allowed us to stabilize some of the highest priority shorelines and added efficiency to the work. Recent projects have been on Martin Lake and the Rum & Mississippi Rivers.
Small excavators work from the barge itself. The barge is moved up and down the shoreline. In this way the equipment is never driven in the water where it would disturb sediment and destroy aquatic vegetation. For more information contact Jamie Schurbon, Wetland Specialist, at
ACD staff recently boated the Rum River to review potential riverbank stabilization and in-stream habitat sites, which provided an opportunity to assess a few previously installed stabilization projects. Each site was stabilized with hard armoring at the bottom of the slope (where vegetation will not grow due to frequent water level fluctuation) and native vegetation on the upper banks. The sites have remained stable, and vegetation has established to provide riparian habitat value within the Rum River Corridor.

Nearly a decade after Minnesota's buffer law was enacted in 2015, 99.8% of parcels adjacent to Minnesota waters are in compliance with the law. Buffers are also known as a riparian filter strip adjacent to a stream, river, lake, or wetland. These buffers filter out phosphorus, nitrogen, and sediment. Studies completed by the Minnesota Pollution Control Agency show that buffers are important for protecting and restoring water quality, natural stream functions, and aquatic habitat and life. Buffers are required along public waterways and ditches. Public waterways include lakes, rivers, and streams. This type of waterway requires a 50-foot average buffer. Buffers of 16.5 feet are required along public ditches.
ACD was proud to announce that Anoka County was 100% compliance back in fall, 2020. This milestone was achieved through strong partnerships between Anoka County, ACD, local landowners, and BWSR. This achievement doesn't mean that the hard work is over but it does represent a great success and displays the impact that strong environmental policy can have across the state of Minnesota. The next phase, includes another ACD review of properties throughout Anoka County to identify non-compliant parcels. This review began in Spring, 2024 and is based on recently released aerial photos. Compliance status and progress is tracked using the Buffer Compliance and Tracking Tool (BuffCAT), a state developed GIS database and mapping system.
Transfers in property ownership and land management changes, will require ongoing efforts by ACD in order to maintain existing compliance and to bring other parcels into compliance. Many landowners with noncompliant parcels have plans in place to seed the sites, or to implement an alternative conservation practice that provides comparable water-quality benefits this spring. Visit the ACD website to learn more about Buffer law implementation or contact Kris Larson, Water Resource Specialist, at
Stormwater runoff from Fridley's Channel Rd. NE neighborhood currently flows to and through the storm sewer network directly to Rice Creek, untreated. This is a common occurrence in well-established neighborhoods built prior to stormwater treatment regulations. However, thanks to collaboration between the City of Fridley, Rice Creek Watershed District (RCWD), ACD, and private landowners, this neighborhood with soon be retrofitted with four curb-cut rain gardens designed to reduce water volume and pollutants entering Rice Creek.
These gardens have been strategically located throughout the neighborhood in order to capture as much runoff as possible. The benefits of infiltrating this stormwater will amount to an estimated reduction of 56,192 cubic feet of water, 3.57 lbs of phosphorus, and 677 lbs of total suspended solids to Rice Creek per year. Each garden will also be densely planted with native forbs, grasses, and shrubs to provide improved water infiltration and pockets of high-quality habitat in a highly developed landscape.
Funding is provided by the RCWD's water quality cost share program and the City of Fridley. Landowners at each garden site have voluntarily enrolled in this opportunity and have agreed to maintain these gardens to ensure long-term functionality. For more information contact Breanna Keith, Water Resource Specialist, at
This June, ACD is planting 10 lakeshore buffers, part of a shoreline stabilization totaling nearly 800 feet of shoreline at three lakes. Native plants help hold in place the shoreline soils against erosion and provide near shore habitat. ACD and its project partners, such as the Sunrise River Watershed Management Organization, have goals of increasing native and stable shorelines.
"Disappearing" natural shorelines is affecting lake health at many waterbodies in the region. ACD staff regularly assists homeowners who wish to do native shoreline buffers. With a little guidance, these projects can be do-it-yourself installation, or professionally installed. Cost share grants are available. Big or small, each is a step toward healthier, cleaner lakes and rivers. For more information contact, Watershed Projects Manager, Jamie Schurbon at

Emerald ash borer (EAB) has left a wake of dead ash trees throughout 4.3 million acres across the state. Minnesota forests are home to three native ash species. Unfortunately, all of these ash trees are susceptible to EAB. Here are seven native tree species that you can research for replacing your ash. Each species has its own unique characteristics and are adapted to different environmental conditions.
American Elm (disease-resistant elm varieties) Like ash, elms can tolerate wet conditions. Elms are slightly different in that they require full sun for the best growth.
Quaking Aspen Aspen sprouts vigorously, a form of reproduction without using seeds. It is often one of the first species to come back to an area after a timber harvest or fire.
Northern White Cedar In its natural habitat, it can form dense stands and survives well in moist soils. Northern white cedar trees will attract wildlife. Cedar trees are a favorite of white-tailed deer.
Swamp Oak This species can tolerate heavy and wet soil, which makes it a good replacement for black ash. While native only to southeastern Minnesota, swamp white oak is known as a climate change "winner" and has been planted with success in research trials in northern Minnesota.
Hackberry It can survive heat and drought or wind and ice, making it suitable for Minnesota's climate. In its native habitat it can be found in floodplains and along rivers in the central and southern portions of the state.
Silver and Red Maple are common in southern Minnesota and grow into the north-central part of the state, typically along rivers. These maples are widely planted as a shade or ornamental trees. Silver maples leaves are are green on top and "silvery" on bottom and red maple leaves turn a brilliant red in the fall, giving the trees their names.
River Birch can thrive in floodplains and near stream banks. River birch can be a single or multi-stemmed tree, making it a great tree to consider for the landscape around your home. Its copper-colored bark makes it stand out from other common trees.
Diversifying the types of species you plant in your yard or woodland gives you reassurance that your landscape can survive future insect and disease outbreaks. For more options, Extension's replacement trees for ash page can help you figure out which trees will grow well in your plant community. Consult an arborist or forester for more advice to make sure you plant the right trees in the right spot.

ACD was recently awarded National Fish and Wildlife Foundation Monarch Butterfly and Pollinators Conservation Funds to increase habitat for the monarch butterfly and other pollinators. ACD is collaborating with Sherburne County Parks and Great River Greening to restore and enhance habitat and create pollinator corridors within the Anoka Sand Plain region. This funding will help support and expand state programs such as the Anoka Sand Plain Partnership and the BWSR Habitat Enhancement Landscape Program.
Sherburne County Parks will coordinate restoration and enhancement activities at Bdé Heḣáka, Omashkooz Zaaga'igaans Regional Park, a new park in coordination with Tribal Historic Preservation Officers from the Upper and Lower Sioux Community and Mille Lacs Band of Ojibwe to restore land through traditional cultural methods. Great River Greening will coordinate projects to enhance large habitat corridors in Sterns, Sherburne, Chisago, Wright, Anoka, Benton and Morrison counties. ACD will coordinate projects within Anoka County.
Unused lots, agriculture fields that are out of production and turf will be restored to create new habitat by planting native milkweed and wildflowers. Degraded lands that have little to no milkweed and forbs will be enhanced by controlling invasive species and conducting prescribed burns. ACD will be hosting events to plant, collect seed, and participate in a national Integrated Monarch Monitoring Program. Details on volunteer opportunities are coming soon!

Spring is upon us! Some of the first plants to emerge are woodland wildflowers known as spring ephemerals. These short lived gems take advantage of the spring sunlight by completing their life cycles before the forest canopy leafs out for the season. In addition to their beauty, spring ephemerals provide critical resources for pollinators as they emerge in the early spring. Common ephemerals include Hepatica, Trout Lily, Bloodroot, and Trilliums.
Among the first plants to green up in spring, garlic mustard outcompetes native spring ephemeral wildflowers, diminishing early season resources for pollinators and degrading forest health. Garlic mustard has a two year (or biennial) life cycle, producing a short basal rosette without flowers in the first year and a tall "bolting" stalk in the second year. It's important to pull these weeds before they produce seed in the second year. Treat garlic mustard by pulling the whole plant and the roots by hand. If you pull garlic mustard before it flowers, leave the material on the ground to decompose. If you pull it after flowering or seed production, bag it and dispose of it properly so that no seeds are spread.
Learn tricks to help identify and treat garlic mustard from the MN Dept of Ag and Friends of the Mississippi River. Help us protect the beautiful and diverse forests of Anoka County by pulling garlic mustard! For more information contact Logan Olson, Restoration Technician, at

ACD staff recently reflected on 2023 to take stock in how well we've been doing to implement our 10-year Natural Resources Stewardship Plan. We looked at 24 Keystone Endeavors across four priority natural resources, our human resource (community), and internal operations. We also considered foundational knowledge gained through monitoring, inventory, analysis and planning. Grades reflect the following:
A - Ahead of plan
B - On track
C - Progressing slower than anticipated
D - No progress
F - Neglected
10-year Goals
A prerequisite to gauge success is to define our 10-year expectations and aspirations for each keystone endeavor based on our current and anticipated staff and financial capacity. Some goals are easily quantified while others are more subjective.

Emergent aquatic plants such as cattails, bulrushes, and sedges grow within the shallow margins, or "littoral zone", of most lakes in Minnesota. These plants improve water clarity as their roots stabilize the lakebed and take in nutrients. Their stems and leaves provide habitat both above and below the water, and they protect shorelines against the forces of wave action. Emergent plants often grow alongside other aquatic vegetation, collectively creating diverse habitat essential to lake health.
Any Destruction of Emergent Vegetation Requires a Permit in Minnesota - Lakeshore owners often wish to remove emergent vegetation to improve their water access. Given the important role emergent vegetation plays in lakes, any removal of aquatic emergent plants requires a permit from the Department of Natural Resources. The permit process connects landowners with professionals to ensure that the extent of vegetation removal (and methods used to achieve it) minimize impacts to the lake. Learn more about aquatic plant regulations HERE.
When Does Emergent Vegetation Become Problematic? - Non-native species such as narrow-leaf and hybrid cattails often grow in dense monocultures that can outcompete native species. Habitat quality and recreation can be quickly reduced as these species spread across large areas of shallow water, but management efforts to remove them are often challenging and costly. When occurring in small clusters, these plants can still provide water quality benefits along shorelines where native emergent plants are absent. In either circumstance, any removal of emergent plants - even if non-native - requires a permit.
Expectations for Living on a Lake - Aquatic vegetation is a natural and important part of lake and wetland systems. The abundance and types of plants present are largely driven by water depth and clarity. Many lakes in the north metro are shallow (less than 15 ft. deep) or are technically open-water wetlands. When paired with good water quality allowing sunlight to reach the bottom, these lakes usually contain abundant vegetation throughout. The alternative is poor water quality from disturbances such as excessive nutrients, which can reduce aquatic vegetation and the fish and wildlife that depend on it. Learn more about shallow lake vegetation from this StoryMap produced by the Rice Creek Watershed District: Aquatic Plants: Guardians of our Shallow Lakes.

ACD has collaborated with BWSR's RIM program to establish conservation easements to permanently protect, restore, and manage natural resources on private lands. Land protection has many benefits including protecting water quality, habitat, creating conservation corridors, and supporting climate resiliency.
In 2023, two new conservation easements were established along the Rum River. They are adjacent to a conservation easement that was established in 2022 through the Rum RIM program and across the river from a DNR Conservation Easement. These conservation easements create a block of protected land totalling 183.5 acres along 10,960 feet of shoreline. The Gamm, Stenson-Gamm, St. Francis Land Development, and MN DNR Conservation Easement create an additional habitat core with functioning ecosystems and enhance habitat in the Rum River corridor.

ACD staff provide technical assistance for a wide-variety of projects each year. Many of the requests for assistance come directly from landowners interested in improving natural resources on their individual properties. Technical assistance is also provided for projects in collaboration with county, city, and watershed entity partners. The table below summarizes 2023 technical assistance provided by ACD staff.
Assistance usually begins with a site consultation. Consultations typically include a conversation with the landowner, desktop review of the site using GIS mapping software and available data sets, and a site visit to discuss options. If the landowner is interested in pursuing a project, ACD can provide design and installation oversight services. Maintenance guidance is also provided for previously installed projects.

Emerald Ash Borer (EAB) is an invasive insect that has killed millions of Ash trees throughout North America. Since 2009, EAB has been detected in 46 counties in Minnesota, including Anoka County. MN is home to over 1 billion Ash trees, all of which are vulnerable to EAB infection.
Trees affected by EAB dry out and rot quickly, creating public safety hazards. If allowed to decay, these conditions can cause trees to become dangerous to manage. Removing ash trees in high-traffic areas including along public trails and neighborhood streets is a top safety priority. Learn more about Emerald Ash Borer on the ACD Website.
Oak Wilt is a fungal disease that affects all species of oak trees. It is spread by sap beetles and through the tree's root systems. The disease affects Oak species differently; it can kill Red Oak trees in 2-3 months whereas White Oaks can live up to 20 years after becoming infested. It's important to know the signs of Oak Wilt to prevent further forest damage. Learn more about Oak Wilt on the ACD Website.
Help Stop the Spread!
Avoid cutting and pruning Ash trees from May 1 - September 31 as EAB insects are most active during this time. Do not transport firewood offsite from where it was collected. The Twin Cities metro and much of Eastern, MN is within an EAB quarantine zone and transporting firewood out of these areas risks spreading EAB.
Avoid cutting and pruning Oak trees from April 1 through July 31 as sap beetles are most active during this time. Treat spring and summer tree wounds with a water based paint or pruning wound sealer to avoid attracting sap beetles. Do not transport firewood off the site where it was collected. The Twin Cities metro and much of east central Minnesota is infested with Oak Wilt. Transporting firewood out of this area risks spreading this forest disease.
The unseasonably warm winter extends the 'don't prune' window and it probably starts in March for 2024.
ACD was a recipient of the MN Department of Natural Resources ReLeaf Community Forestry Grant to help efforts to manage Oak Wilt and EAB in Anoka County. A variety of tree species will replace those affected by Oak Wilt in the Anoka Nature Preserve (ANP), including treating Common buckthorn in 2024-25 to free up space for new trees to be planted in 2026. Ash trees at Kings Island in the City of Anoka will be removed in early 2024 and new trees will be planted in 2025. Planting at both of these sites will be completed with the help of volunteers. If you have interest in helping out as a volunteer, sign up here!

The proposed removal of Golden Lake from Minnesota's impaired waters list was highlighted in a recent Board of Water and Soil Resources (BWSR) article that underscores the importance of Clean Water Funds (CWF) for measurable water quality improvement. ACD secured two CWF grants for iron-enhanced sand filters (IESF) to reduce phosphorus reaching Golden Lake, located in Circle Pines, MN. Iron-filings mixed throughout the sand, capture phosphorus from stormwater passing through the filters. One IESF was installed in Centennial Green Park (2015) in the City of Blaine, and the other was installed in the City of Circle Pines (2019). Both projects were identified as cost-effective phosphorus reduction options in a Golden Lake stormwater retrofit analysis completed by ACD.
The proposed delisting of Golden Lake is a testament to the hard work and collaboration by many, including ACD, the City of Blaine, the City of Circle Pines, and the Rice Creek Watershed District. Mitch Haustein, ACD's Stormwater and Shoreland Specialist, assisted with the projects and was interviewed for the article. Click here to read the full article from BWSR that also includes brief stories about proposed delistings for 6 other Twin Cities area lakes, 1 Wright County river reach, and 1 Winona County stream segment.

Minnesota's natural resources play an important role in the state's economy and high quality of life. Protecting and managing these precious natural resources is a large undertaking and takes continuous effort at the state and local level. Soil & Water Conservation Districts (SWCD's) throughout the state are governed by a five member board of supervisors elected by the citizens of the county. The SWCD board is responsible for policy development, annual plans, budgets, and more. The Anoka Conservation District will have three supervisor positions on the November 2024 ballot. These positions are four-year terms and require between 1 to 3 monthly meetings and receive modest compensation per meeting.
The following districts in Anoka County will be up for election:
District 1 - Anoka, part of Coon Rapids, Nowthen, Oak Grove, Ramsey, St. Francis
District 4 - Portions of Blaine and Coon Rapids, all of Lexington
District 5 - Bethel, Centerville, Circle Pines, Columbus, East Bethel, Ham Lake, Lino Lakes, Linwood Township
Filing is easy but must happen between May 21 and June 4. Just go down to the County Government Center in Anoka during that time and they'll tell you what to do.

This past month, ACD and partner staff completed an 8 hour chainsaw safety training course. The skills and safety tips learned will be applied while clearing large buckthorn, cutting cedar trees for streambank stabilization projects, and while addressing other natural resource concerns that come our way. Winter is an ideal time to cut or trim oak and ash trees without the high risk of spreading oak wilt and emerald ash borer diseases. If you plan to cut trees on your property this season, remember the following tree felling rules:
Hazards- Survey the area to identify and remove any potential hazards.
Hinge- Create a hinge for safe and predictable felling. See an example notch here.
Escape- Have 2 escape routes at 45 degrees from your cutting direction.
Lean- Analyze the tree from all angles to ensure you understand its weight distribution and lean direction.
Plan- Have a plan to complete a safe and predictable cut. Click here to learn how to execute the bore cut.
Having the right training and equipment can spare you from serious harm when using a chainsaw. Take the time to educate yourself on proper safety equipment and risk management strategies. Safe cutting! You can read a description of the training course here or contact Logan Olson, Restoration Technician, at
A hallmark of ACD's natural resource work has included the stabilization of eroding riverbanks and the enhancement of native vegetation in adjacent riparian and floodplain areas. These activities improve water quality in the river and habitat quality along it. Included in the goals of our Phase 2 grant for Rum River habitat enhancement through the Outdoor Heritage Fund of the Clean Water Land and Legacy Amendment is the improvement of in-stream habitat in the Rum River channel. This is a new endeavor for ACD that presents an exciting opportunity to expand our work and our partnerships within the Rum River Corridor.
Though we are over a century removed from the widening and scouring of the Rum River by the millions of logs cut during the Minnesota timber boom, the effects of that industry still remain. Rivers used as log arteries were made wider and more consistent to ensure the smooth sailing of logs downstream. In more modern times, towns piped rain water directly to the river from impervious areas via stormwater conveyance systems. These rapid spikes in water input during storms exacerbate bank erosion, down-cutting, and sedimentation in the river at rates far beyond what was natural.
Due to this historical usage of the Rum River as a conveyance tool for wood and stormwater, habitat for fish, invertebrates, mussels, and other aquatic life remains lacking and out of balance. In the coming years we will be partnering with Anoka County Parks, DNR Fisheries, The Nature Conservancy and others to identify and enhance missing or deficient in-stream habitat. Secondarily, we will look for enhancement opportunities for game fish habitat near publicly accessible shorelines to improve access to quality shore fishing.

Wildlife management areas (WMAs) are part of Minnesota's outdoor recreation system and are established to protect those lands and waters that have a high potential for wildlife habitat and other compatible recreational uses. WMAs are key to:
How did WMAs get started?
Minnesota's WMA system started in 1951, when the State established its "Save the Wetlands" program to buy wetlands and other habitats from willing sellers to address the alarming loss of wildlife habitat in the state. Initiated by a handful of visionary wildlife managers, the WMA program evolved into the present-day system of WMAs.
How many WMAs are there and where are they located?
There are over 1.3 million acres of high quality habitat in about 1,500 WMAs located throughout the state, making it one of the best and largest WMA systems in the country.
How are WMAs managed?
WMAs are the backbone of DNR's wildlife management efforts in Minnesota. Much of the wildlife managers' work is directed toward protecting and enhancing wildlife habitat on WMA lands. For instance, prairie and grasslands are planted, wetlands are restored and enhanced. Prescribed burning is done to maintain grasslands, prairies, and brush lands. Forest openings and regeneration projects benefit create wildlife habitat. Different management practices are utilized for different ecotypes.
What can I do to help?
There are opportunities to volunteer at WMAs by picking up trash to assisting with seed collection and much more! For more information and locations of WMAs go to this link https://www.dnr.state.mn.us/wmas/index.html.

The elected Board of ACD is moving forward with legislation to have the ability to levy property taxes for residents of Anoka County. With the levy limits included in the bill (HF3701) and ACD's other revenue streams, the anticipated levy increase for the average single family home in 2025 through 2029 is around $0.67 per year. Why bother pursuing legislation for such a small levy? That's a long story, but here's the gist of it.
"So what you're saying is that if ACD gets its way, a family of four in Anoka County will have to give up one fancy cup of coffee every four years for cleaner lakes and rivers, better fishing, improved habitat for wildlife, and safer drinking water?" Well, when you put it that way…

Each season, local high school students venture to a nearby river or stream, grab a dip net and pair of waders, and search for invertebrates (a mix of aquatic insects, crustaceans, bugs, snails, worms, and other critters lacking a backbone) living amongst the submerged rocks and vegetation. They bring their catch back to their partners on shore, who use guides to identify the invertebrates or preserve them for identification at a later date in the lab. In 2023, ACD staff led 560 high school students across 20 classes and 5 schools in these "biomonitoring" efforts. Besides being a great way to get some fresh air, students learned valuable lessons in aquatic ecology.
Individual aquatic invertebrates have different sensitivities to environmental disturbances such as contamination and habitat loss. Some, such as stonefly and mayfly nymphs, often have a strong negative reaction to disturbance, while others, such as leeches, midges, and aquatic worms, are usually more tolerant and able to persist through a variety of conditions. Understanding these tolerance thresholds across species is an efficient way to broadly assess the health of a waterbody. For example, a high quantity and/ or diversity of species including those considered "intolerant" (sensitive) is a likely indicator of healthy habitat and water quality, whereas the presence of only more "tolerant" species hints at poorer water quality and habitat. Biomonitoring data is often paired with other information, such as water quality or stream morphology data, to identify where aquatic impairments are present and management efforts should be pursued.
After the students have finished collecting and processing samples, ACD staff re-identifies them and summarizes the data in the annual Water Almanac. Through this, big-picture trends in invertebrate communities (and stream health, by extension) can be explored across time. For more information contact Breanna Keith, Water Resource Technician, at
The Anoka Sand Plain (ASP) Rare Plant Rescue Program had a busy year in 2023! Thanks to the assistance of partners and volunteers, we:
Looking Forward:
Recently, I have seen some pushback from folks who say that asking the general public to recycle, conserve water, reduce their carbon footprint, etc. is inconsequential compared to commercial impacts and thus misguided. The consensus that corporations and governments have an outsized influence on these environmental impacts and private citizens contributions to the problem don't matter. Here are two articles in the Scientific American or The Atlantic, that discuss this issue in more detail.
Though I don't disagree that commercial/agricultural uses oftentimes outweigh residential uses (e.g. pesticide and fertilizer application); I also believe that if enough people adopt enough measures we can make a difference in a twofold manner. One, we will be more aware of how corporations operate and through purchasing power and/or legislation create changes that benefit the resource. Check out this awesome resource developed by USGS and learn more about water use in your local area.
In another case, because of both residential and commercial changes in habits; we have actually reduced water usage dramatically in the last 3 decades. We should celebrate this because clean water is not infinite. There are still issues surrounding water quantity (and quality) and we can never sit on our laurels but we can make a difference one drippy faucet at a time.

Twenty-years ago we designed conservation projects with a tape measure and graph paper. Over the years, ACD has gone high tech. Today we use a survey-grade GPS (shared with neighboring SWCDs) and landscape design software. This allows precise measurements and estimates of quantities. It also allows us to clearly communicate a project's outcomes to landowners and contractors. But we still pull out the tape measure once in a while – it never crashes or fails to connect.
We're the private lands conservation experts! We provide financial resources and expertise to help private landowners with conservation efforts on their property that also have public benefits. Minnesota is a unique state, with an SWCD in nearly every county to assist with work on the ~70% of Minnesota's lands that are private. ACD is simply an SWCD that shortened its name. In comparison, the well-known MN Department of Natural Resources (DNR) manages public lands and resources.

Unused wells can serve as direct conduits for surface contaminants to reach our aquifers. ACD was awarded a grant in 2020 through the Clean Water Fund to help eligible landowners seal unused wells located within Anoka County. This program has been extended to run through 2024 in order to continue to to provide local residents assistance with sealing an unused well on their property!
A well is defined as "not in use," when the well is not functional, cannot readily pump water, or has not been operated on a regular basis. A "not in use" well has not been sealed by a licensed well contractor. A well that is "not in use" (i.e., "abandoned") must be repaired and put back into use, permanently sealed by a licensed well contractor, or the owner must obtain a maintenance permit. In many cases, placing an old well back into use is not practical. Sealing your well is also legally required when you go to sell your home. If your house was built before public water was available, the property may have one or more wells. Wells can be located either inside or outside a residence.
Indoors look for:
"What good is the warmth of summer, without the cold of winter to give it sweetness?" wrote John Steinbeck. We know that Minnesota winters ban be frigid, making people more likely to stay indoors. Many residents are unaware of all the great activities are out there to keep you from becoming stagnant in the winter months and able to stay healthy and happy. Sometimes winter activities are even more exciting and offer experiences that you don't get during other seasons. Cold-weather camping is a great way to savor those special moments but many folks, even experienced campers, think the idea sounds crazy. Click here to learn more about the basics of winter camping from the Sierra Club.
To help Minnesotans plan winter visits to state parks, and other recreational areas, the Minnesota DNR shares its top tips to have fun this winter, along with other resources for planning a winter adventure. "We know Minnesotans love being outdoors, and winter offers a whole new way to play outside," said Ann Pierce, the DNR's Parks and Trails Division director. "However, we also know cost and information can be barriers for Minnesotans to get outdoors and enjoy nature. We're working to alleviate this for folks by providing no cost or low-cost activities and providing easy trip planning resources."
Believe it or not, winter is a busy time of year for ACD's field crew. This winter, our buckthorn crew has started a five-year restoration project at Lamprey Pass Wildlife Management Area (WMA) in Columbus, MN. A popular destination for waterfowl hunting, Lamprey Pass is the second largest WMA in the North Metro.
The Lamprey Pass site is currently overrun with common buckthorn, a large invasive shrub that crowds woodland understories and shades out native plants. ACD's crew is working hard to remove this invasive plant from the WMA, creating a more open habitat which will benefit native plant species and make the woodlands more hospitable for hunters. The images above and below demonstrate the impact of clearing buckthorn on the site. For more information about treating buckthorn, contact Logan Olson, Restoration Technician at Logan.Olson @AnokaSWCD.org
Stormwater runoff from human-modified landscapes is a source of excess water and pollutants that can significantly impact rivers, lakes, and wetlands on the receiving end. However, not all drainage areas are created equally; rural landscapes with abundant agriculture and artificial drainage features, or urban areas with infrastructure predating stormwater treatment regulations, are often the most impactful. Areas draining to a priority waterbody are targeted for Subwatershed and Stormwater Retrofit Analyses (SRAs and SWAs). In these analyses, we study how runoff is moving through the landscape, strategically place various Best Management Practices (BMP's), and estimate their anticipated water quality benefits and installation costs. These findings are then summarized into a report which can be referenced by ACD staff and local natural resource managers to pursue the most cost effective projects.
ACD has completed several SRA/ SWA reports, but current efforts are focused on areas draining to the Rum and Mississippi rivers. Projects sited in these areas include rain gardens, subsurface treatment structures, enhanced street sweeping, wetland restorations, soil health practices (cover crops, no- till farming, etc.), and targeted agricultural practices (grassed waterways, riparian buffer enhancements, control basins, etc.). Altogether, approximately 150 urban BMPs and over 300 rural BMPs have been sited, and their associated SRA/ SWA reports will be released in the coming months.

I've been dabbling with how to leverage artificial intelligence (AI) to improve productivity at ACD. Using ChatGPT, I've found a tool that can help generate an outline to serve as a jumping off point when starting a report or project plan. Recently, groundwater contamination problems have been popping up in the news. Within two Andover neighborhoods, residents with contaminated private wells are reduced to only using bottled water until they can hook up to city water. The plume of contamination below their homes, now plaguing them, will certainly continue its journey, ominously passing under neighborhoods in its path. Those hooked up to city water supplies will be fine. Those on wells, may be in for an unsettling surprise.
Where does AI come in? I asked ChatGPT to write a short somber poem about groundwater pollution. Here you go…
Beneath the soil, where secrets flow,
Groundwater whispers, tainted below.
Pollution seeps, a silent intrusion,
Nature's tears in liquid confusion.
Once pure, now stained with human's trace,
A solemn grave for life's embrace.
Quietly it suffers, unseen and still,
Groundwater mourns, a poisoned rill.

The Apex Pond enhancement project in the City of Fridley is complete! Project planning began in 2022 with surveying, testing soils for on site contaminants, and design development. Construction began in fall, 2023 and spreading native seed and securing erosion control blanket over the upper slopes surrounding the pond were the final elements needed to complete installation. Originally constructed in 1999 with a ponding depth of one foot for rate control of runoff, the enhanced pond is approximately six feet deep and provides water quality treatment for nearly 90 acres of residential neighborhoods. The increased ponding depth enables sediment and nutrients to settle and accumulate in the pond basin.

In Anoka County, the Rum and Mississippi Rivers are designated State Water Trails. Like many state trails, information is available about trail access, places to camp, culturally significant areas, and more on the MNDNR's water trails website. ACD is completing a number of projects along both rivers to improve water quality and habitat. We've been especially busy with projects along the Rum River that include wetland restorations, riverbank stabilizations, invasive species management, and habitat protection. Many of these projects are funded in part by the Clean Water, Land and Legacy Amendment.
Prairie once covered 1/3 of Minnesota. Today only a little more than 1% of native prairie remains. Prairie is a key habitat for 34 Species in Greatest Conservation Need (SGCN) and for many at-risk pollinators in Minnesota. It is important to maintain and enhance the little prairie that is remaining to help out these important species. Anoka County Parks maintains prairie habitat on County land with prescribed burns every 3 to 5 years. ACD helped manage weeds before the scheduled burns and overseeded a custom seed mix for each site after the burns. The native seed mixes contain species that are minimally present or not present at all the prairie units. Species that benefit at-risk pollinators were included in the mixes. The goal is to enhance the prairies by reducing non-native weeds and increasing native biodiversity.
Bunker Hills Regional Park Pasture Unit includes a wetland depression surrounded by dry prairie. Site preparation involved controlling non-native woody encroachment and monoculture patches were sprayed or mowed. ACD overseeded following a prescribed burn in the fall. The seed mix contained 41 different forb species and 5 different grass species. A mix of wildflowers provided pollen and nectar sources for several endangered species of Bumble Bees.

Inventorying shoreline zones on surface waters throughout Anoka County serve as valuable tools for assessing lakeshore and riverbank conditions, comparing current conditions to previous years to identify changes, and for prioritizing project implementation. ACD recently purchased a 360° video camera that has 4 high-definition lenses and a rugged design, to be used outside in the elements. The camera takes continuous video that is Geo-located and stitched together creating a final GPS video that is viewable from all angles. Following a day on the water with the 360° camera, videos are uploaded to Google Street View Studio, a new application recently released by Google.
Once uploaded to the Google Studio App, the videos are public and accessible to anyone. ACD utilizes these videos to compile shoreline reports, which describe erosion severity and provide recommendations for project needs. Shoreline videos along Martin, Coon, Linwood Lake, the southern portion of the Mississippi River, and Oak Glen Creek were collected throughout 2023 and are now available to view. Click on the individual links above to begin exploring. Videos along the Rum River were also collected and will be available to the public soon!

ACD has a new Board Member for District IV. Kate Luthner was officially sworn in on November 20, at the ACD office. Kate is a 20-year resident of Minnesota and lives with her husband and three kids in Columbus. She enjoys hiking, biking, gardening, and reading and painting for those cold winter months. Kate previously served on the Forest Lake Area School Board and volunteers with several other local organizations. Kate has a BA from Cabrini University and an MBA from the University of St Thomas. She is excited to learn more about the role of SWCD's and how ACD is working to preserve and enhance the world we all share.
During a recent site visit to explore wetland restoration opportunities, ACD staff came across a fantastic example of beavers' "engineering" skills in action! A series of three beaver dams, located near the outfall of a Rum River tributary, were effectively slowing and spreading the stream's flow into the surrounding floodplain wetlands. Healthy connections between streams and their floodplains provide numerous water quality and habitat benefits, and in this case those benefits also extend to the Rum River immediately downstream.
Many streams in modified landscapes take on excess water from artificial drainage features like ditches and storm pipes. Over time and especially during extreme precipitation events, these higher volumes of water often increase erosion within the stream, which can lead to the straightening and downward-cutting ("downcutting") of the stream channel and, as a result, the disconnection of the stream from its floodplain (see the figures below, produced by American Rivers).
Floodplain reconnection efforts are an increasing priority amongst many conservation organizations, but they can be costly and complicated – particularly if development has occurred within the floodplain. However, in areas where streams have room to spill into their floodplains without causing damage, allowing and even promoting beaver activity can be a cost effective way to help restore riparian corridors. Learn more about the benefits of beavers in the articles below.

"Climate is more than just numbers." – Jim Zandlo
Eight Martin Lake residents, in collaboration with ACD, are bundling their individual lakeshore improvement efforts into one larger project. By joining efforts, they are hoping to save money while making the work more attractive to contractors. It seems to be working, as 15 contractors joined in the bidding process!
This upcoming project is being coordinated by ACD, who has completed designs and will be providing construction management. ACD has also been able to incorporate three state grants, making the project even more affordable. In exchange, the landowners are installing lakeshore stewardship practices that go above and beyond – utilizing natural materials, native plant buffers, and aquatic vegetation for habitat. Collectively, we'll make a healthier lake.
For a fun & informative 8-minute video about healthy lakeshores, watch ACD's video "Our Lakeshore Connection." For more information contact Jamie Schurbon, Watershed Project Manager,
Construction of the Apex Pond enhancement project in the City of Fridley is nearly complete (see pictures above). The only remaining elements are to spread native seed and lay erosion control blanket over the upper slopes surrounding the pond. Apex Pond in the City of Fridley was originally constructed in 1999 to help control the rate of stormwater runoff entering Springbrook Creek from nearly 90 acres of residential neighborhoods. ACD, in partnership with the City of Fridley and the Coon Creek Watershed District (CCWD) identified an opportunity to enhance the water quality treatment capacity of Apex Pond by increasing the pond's storage volume.

Minnesota boasts an impressive 12,208 lakes, as classified by the Minnesota DNR. Among them, 8,402, or roughly 69%, are classified as 'natural environment lakes.' Anoka County is home to several natural environment lakes including Fawn, South Coon, and Island Lakes.
What defines a natural environment lake? These are the smaller, shallower lakes, typically less than 150 acres in size and less than 15 feet deep. They come with numerous developmental constraints and are particularly sensitive to disturbance. With lakeshore properties in high demand across Minnesota, many natural environment lakes are now being earmarked for development. However, it's important to note that the lakeshore experience offered by these lakes might not align with the typical desires for boating or swimming that potential buyers often have.
Learn more about natural lakes on November 8th through a webinar featuring Joe Bischoff, an aquatic ecologist at Barr Engineering Co. Joe will delve into the intricacies and benefits of natural environment lakes. Additionally, some of the ongoing local conservation efforts to monitor and protect natural environment lakes will be highlighted.

ACD strives to build resilient pollinator corridors throughout Anoka County. This goal is accomplished by protecting and enhancing existing habitat and creating new habitat. ACD is fortunate to have local partners who also share this vision and are helping identify unused turf areas that can be converted to native plantings. ACD is currently working with the Cities of Fridley and Blaine to convert turf into prairie plantings in public green spaces. Half an acre of turf is being converted in Fridley's Commons Park and 0.3 acres of turf to prairie at Blaine's Laddie Lake Park. Staff from both cities prepared the sites and mowed the sites to prevent weeds from seeding. ACD staff seeded the sites in the spring. Members of the Cities and multiple volunteer groups planted native grasses and wildflowers to add to the seed mix.
These projects are funded by BWSR's Habitat Enhancement Landscape Pilot (HELP) grant. Other ACD HELP turf to pollinator projects are at Coon Lake County Park, Bunker Hills Regional Park and Ramsey River's Bend Park. The BWSR HELP grant also provides funds to enhance native prairies at the Cedar Creek Conservation Area, Bunker Hills Regional Park, Rum River Central Regional Park, Rice Creek Chain of Lakes Park Reserve and Mississippi West Regional Park.
One way to help these projects is to donate your native prairie seeds, including milkweed seed. See ACD's previous post about milkweed seed collection. Watch this short video to see butterfly milkweed seed cleaning.

Minnesota is rich in wetlands which provide numerous benefits such as flood mitigation, groundwater recharge, water quality improvement, recreation, and high-quality habitat for a wide variety of fish and wildlife species. However, many wetlands exist in a degraded state due to decades of human disturbances such as drainage and filling to increase usable land for agriculture and urban development.
Recognizing their importance, many federal, state, and local agencies have developed programs to provide technical expertise and funding for wetland restoration projects. The goal of wetland restoration is to return a wetland to its natural functions, and the nature of each project depends on the wetland's unique location, hydrology, soils, vegetation, and impacts (historic and current).
Restoring wetlands on your property adds to its ecological value and can often be financially beneficial. Understanding your options can be complicated, which is why ACD – on behalf of, and with funding from, the Rum River Watershed Partnership – created a new wetland restoration brochure. In it, you will find information on benefits, approaches, processes, and funding options common for wetland restoration projects. Click here to access the brochure below.
Anoka County Residents: ACD currently has funding to support wetland restorations benefitting the Rum River! If you live near the Rum River, believe that you have impacted wetlands on your property, and are interested in restoring them, please contact Breanna Keith, Water Resources Technician, at
Construction is set to take place in October along 630-feet of eroding Rum Riverbank at Dellwood River Park in St. Francis. Erosion of the riverbank is causing numerous trees to fall into the river and is threatening a popular local walking trail. The project design features three primary protection measures;

ACD has been awarded additional funding through the Minnesota Pollution Control Agency for septic system repair or replacement. Grants are currently available to homeowners to help fix non-compliant septic systems. Septic systems are the underground tank and drain field that treat wastewater from homes that are not connected to city sewer and water. Grants recipients must meet low income criteria and other requirements listed below.
A non-compliant septic system is a problem for homeowners, an obstacle when selling the property, and a major pollutant threat facing our waterways. Failure in a SSTS system can be dramatic, such as visible sewage back up. Or a septic system can be deemed non-compliant for a more hidden reason, such as the system does not have enough vertical separation from the water table. When a system is certified as non-compliant it represents a direct threat to groundwater, public health, or both. The proximity of a failing septic system to nearby lakes and streams is also considered when awarding grants.

Apex Pond in the City of Fridley was originally constructed in 1999 to help control the rate of stormwater runoff entering Springbrook Creek from nearly 90 acres of residential neighborhoods. ACD, in partnership with the City of Fridley and Coon Creek Watershed District (CCWD) identified an opportunity to enhance the water quality treatment capacity of Apex Pond by increasing the pond's storage volume.
Project construction will consist of two phases: 1) maintain the pond by removing accumulated sediment and undesirable vegetation to restore original function, and 2) enhance the pond by increasing the depth to approximately six feet. Mature trees around the pond will be preserved where possible and native vegetation will be used to restore the pond side slopes. A vegetated, level bench will also be incorporated around the perimeter of the pond to provide habitat value and increase safety.
Both Springbrook Creek (County Ditch #17) and the Mississippi River will benefit from the project as the pond outlets to Springbrook, and Springbrook is a tributary to the Mississippi. Total annual reductions to Springbrook and the Mississippi River include 16.80 lbs-TP/yr and 6,617 lbs-TSS/yr. Construction is tentatively scheduled to begin in early October.
Pond maintenance will be funded by the City of Fridley, and pond enhancement will be funded with a combination of Watershed Based Implementation Funds from the Board of Water and Soil Resources, a CCWD Water Quality Cost-Share Program grant, and the City of Fridley.

A rain garden at the Coon Lake Beach Community Center needed a little help. Originally constructed in 2015, maintenance had reached a point where a group effort was needed to reclaim the garden from weeds and silt overload. The Community Center leaders enlisted a local boy scout troop, their parents, and ACD to help.
The rain garden has an important function in the neighborhood as it is positioned near the bottom of a hill to collect street runoff. Instead of going into the lake at the bottom of the hill, the water and associated pollutants are treated by infiltration. The reduction in volume of water running towards the lake also helps alleviate shoreline erosion in specific problem spots.
In one-hour the scouts completed several renovations to bring back much of the original beauty and function. They removed four trailer loads of invasive trees including many thorny black locust. They removed sediment that had collected and was damming the rain garden entrance. Rocks and retaining walls were cleared of debris, leaving the garden with a more formal appearance and ready for the next rainfall. Great job scouts!
Knotweed is a species of increasing concern with several new populations across Anoka County. Knotweeds are herbaceous shrubs characterized by a sturdy, bamboo-like stalk which can grow to over 10 feet in a single season. They grow aggressively, especially along riparian areas where they outcompete native vegetation and create bare ground which enhances erosion damage. Knotweed can also grow through sidewalks and concrete foundations, damaging infrastructure.
There are three species of knotweed in MN: Giant, Japanese, and Bohemian which is a hybrid of the first two. All three Knotweed species are on the state noxious weed list as Prohibited Control species. Efforts must be made to stop their spread and propagation. Late August into September is the easiest time to spot Knotweed infestations due to their showy white flowers. You can help keep this species under control by entering sightings into EDDMaps or reporting them to ACD staff.
See links for Giant, Japanese, and Bohemian knotweed ID and knotweed management guidance from the MDA.

At the beginning of August, we released 100 root boring weevils to help control a population of spotted knapweed at the Anoka Nature Preserve (ANP), in the City of Anoka. Spotted knapweed is an invasive plant native to Eurasia that is spreading across Minnesota. It releases a toxin that threatens nearby plants, giving it the tools to outcompete and dominate, and thereby decreasing biodiversity.
Root boring weevils are a method of biocontrol that target knapweed without affecting surrounding native plants. As larvae, root weevils burrow into the roots of spotted knapweed and feed on them throughout winter and spring, leaving the plants dead or weakened. The weevils we released at ANP were adults who will lay their eggs at the base of the plants through early fall and hopefully begin to weaken the population of spotted knapweed within the preserve.
ANP was a promising candidate for root weevils biocontrol because the site has a large, dense population of spotted knapweed, and the weevils will not be disturbed by mowing or other land management activities. It can take several years to see the effects of the weevils, and the site will be monitored to see if they have been established. The weevils were provided by Monika Chandler from the MN Department of Agriculture, who delivered them in a sealed paper cup where they were kept refrigerated or in a portable cooler until the time of their release later in the afternoon.

The City of Anoka successfully secured funding from the Minnesota Legislature to complete a feasibility analysis and project design, which should be complete by the spring of 2024. City of Anoka civic leaders and staff have embarked on a path to reimagine how the Rum River Dam in Anoka can serve the community for the next 100 years. The vision includes the following.
The option that is on the table is a constructed stream that flows around the side of the dam. Inspired by nature, it does its best to mimic natural streams providing irregular flows and small pools to rest along the way. The Oswegatchie River fish bypass at the Heuvelton dam in New York recorded 2,000 migratory fish of 14 species in 5 days in the first season it was opened. A group of experts has been assembled to provide crucial guidance over the coming months to ensure the designs for the fish bypass element of the project optimize success for targeted fish species.
