Chloride Trends in the Rum River Watershed

The Metropolitan Council (MCES) put out a report on the trends of chloride in the Rum River Watershed. This report was based on data collected from 2001 to 2019 by both the MCES and Anoka Conservation District. Chloride concentrations have been rapidly rising in many waterbodies, including shallow aquifers, throughout Minnesota. This is a worrying trend because chloride is a permanent water pollutant that is toxic to fish, aquatic bugs, and amphibians. The main sources of chloride pollution in Minnesota comes from livestock excreta, household water softening, synthetic fertilizer, and de-icing salt. Chloride concentrations can be greatly affected by other factors like season, precipitation, and streamflow. During the winter months, concentrations rise with the use of approximately 400,000 tons of de-icing salt on Twin Cities' roads. Precipitation and streamflow also affect the concentration by dilution during high flow and precipitation years and concentration during low flow and precipitation years.

Luckily, the MCES found that concentrations of chloride are generally low in the Rum River. Chloride was increasing from 2001 to 2012 but has remained stable since 2012. Although this is a good sign, climate change is creating a wetter, warmer climate in Minnesota. This will greatly affect the freeze-thaw cycle and will have an unpredictable affect on pollution dynamics. Understanding how pollutants like chloride can affect Minnesota's waterways is an important step in keeping our waterways clean.

Coon Lake Lakeshore Restoration – One Year Later

One year ago, ACD partnered with the Sunrise River WMO and a homeowner on Coon Lake to restore a damaged and degraded shoreline to improve water quality and lakeshore habitat, as well as promote native plant diversity and pollinator habitat. The shoreline was degraded by waves and ice, mowing of turf grass to the water's edge, and further damaged by tunneling muskrats. To correct these issues, the shoreline was regraded to a more gentle approach to the water, a muskrat deterrent was buried along the shoreline, and turf grass was replaced with native plants ranging from aquatic-emergent at the water's edge, to upland plants further up the bank.

The project was installed in July of 2020, and despite the recent drought, has flourished after one year of growth. Creating a diverse, native lakeshore can often be as simple as no longer mowing turf grass near the water's edge and planting native shoreline plants to create a more natural buffer area. The Anoka Conservation District can offer technical assistance to any landowner interested in creating a more beneficial shoreline, and oftentimes can bring financial assistance to a project as well.

Restoring Hydrology and Wetland Habitat at Cedar Creek Conservation Area

The Anoka Conservation District, US Fish and Wildlife Service, and Anoka County Parks are collaborating to restore hydrology and enhance five acres of wetland and one acre of upland prairie at Anoka County Park's Cedar Creek Conservation Area. Two wetland basins were enhanced by installing sheet piling ditch plugs and adding fill material in a private ditch that was draining the wetlands. A berm to prevent water from entering the ditch was constructed to enhance a third wetland basin. Non-native reed canary grass biomass and root sod was scraped from these wetland basins and used to fill the ditch. Construction is complete and vegetation management will occur on these three basins and two additional basins in the area for the next five years using funds from the Lessard-Sams Outdoor Heritage Council. The goal is to convert these once drained wetlands that were dominated by reed canary grass to wetlands with native vegetation and greater water holding capacity. This will provide benefits to water quality and improve wildlife habitat.

Long Term Success of Cedar Tree Revetment Projects in Anoka County

Cedar tree revetments are a cost-effective bioengineering practice that can be used to stabilize actively eroding riverbanks. This spring, staff from the Army Corps of Engineers (USACE) visited several cedar revetment projects that ACD had installed between 2002 and 2016. The two staff from the USACE had been traveling to several states to review what is working and what is not working when it comes to cedar revetment projects. They are hoping to use the information to publish technical notes and/or peer reviewed literature.

They were very impressed by the effectiveness of ACD's revetments, even the very old ones. They attribute this effectiveness to the removal of the back branches. They had not seen this technique in any other state they had visited. Most cedar revetment failures studied, seemed to come from the trees moving/floating during high water and scour behind the trees causing more erosion. They also saw many trees that snapped in half, which was potentially from the stress of so much movement. They are planning to highlight the technique of removing the back branches in any published literature.

Almost all of ACD's revetments visited were still in place. Most had stopped, or greatly decreased erosion at the toe but did not fill in with sediment. The most common failure was broken wire that held the tree to the duckbill anchor. In most of these cases, the trees did not move a lot from where they were originally placed. The breakage seemed to be caused by rust.

Rum River Cedar Tree Revetments

The Anoka Conservation District has been working hard in partnership with Conservation Corp of MN and the Anoka County Parks Department to implement Cedar Revetments along the Rum River. So far nearly 1,500 linear feet along the Rum has been protected using the bio-engineered practice. These practices have been installed on private lands as well as property managed by Anoka County Parks. This type of practice is effective at protecting the bank from erosion while also enhancing shoreline habitat for wildlife. Cedar revetments are also much less expensive compared to other stabilization techniques. Through a state grant awarded to Anoka County Parks, there is currently funding available to cover 90% of the total project cost.

If you own property on the Rum River and are interested in protecting your shoreline, please contact Kris Larson for more information. 763-434-2030 x110, This email address is being protected from spambots. You need JavaScript enabled to view it..

Rain Gardens for Rice Creek

Street reconstruction projects often provide opportunities to install new projects that can benefit water quality in nearby waterbodies. In the City of Fridley, up to six curb-cut rain gardens are currently being designed in conjunction with a street reconstruction project. The designs are being done by ACD in partnership with the City of Fridley, the Rice Creek Watershed District, and landowners. The rain gardens will capture stormwater runoff before it enters the storm sewer system, which discharges to Rice Creek.

Depending on the underlying soils at each site, rain gardens with sandy soils will use infiltration (i.e. the water will soak into the ground) while those with finer soils (e.g. silty soils) will filter the runoff before discharging the cleaner water to the storm sewer system. In both cases, Rice Creek will benefit from reduced loading of sediment and nutrients.

High priority properties with large contributing drainage areas were targeted. Those properties with landowners willing to transition some yard space out near the road from turf grass to garden area and agree to provide maintenance are being considered for rain garden installation. Funding will be provided by the City of Fridley and the Rice Creek Watershed District.

Watch for additional updates as designs are finalized and the rain gardens are installed. To see other rain gardens already installed throughout Anoka County, please see the virtual project tour on ACD's website.

Please Water Responsibly

This summer has been very dry. As a result, many cities around the metro have implemented watering bans or restrictions. Watering daily during drought conditions puts further strain on water supplies than the drought is already causing. Watering allowance during restrictions (e.g. odd or even days only) should be thought of as the MAXIMUM you should water, not the minimum. If your grass is green and lush, consider shutting your sprinklers down for a day or two. Selectively water areas of your yard that may be sunnier or drier where the grass browns more readily, but consider skipping areas that stay green longer. In times like these, it becomes even more important that we share our limited water resources responsibly.

Use these additional tips to conserve water this summer:

  1. Use sprinklers efficiently. Align sprinklers to avoid irrigating roads, sidewalks, and driveways. Install a rain sensor on automated irrigation systems.
  2. Water deeply and less frequently rather than daily. The only exception to this is when you start seeds which require moisture for germination. When plants are watered less frequently they grow deeper roots and become healthier plants.
  3. Water in the morning. Watering in the morning prevents water loss from evaporation and also prevents possible fungal problems if plants remain wet in the cooler night.
  4. Mulch your garden beds with wood chips, leaves and unsprayed straw. Mulching around the plants in your garden will help conserve soil moisture.
  5. Add organic matter. Adding a layer of compost to your beds every season will increase the water holding capacity of your soil.
  6. Install a rain barrel. Harvest water from rooftops during rainstorms and use that water to water gardens.

New Grants Secured in Northeast Anoka County

This spring, long time Martin Lake residents Wally and Nancy Olson challenged the other members of their lake associations: donate $3,000 for lake water quality improvement and we'll match it. In just a few weeks $3,600 in donations poured in, including 21 households that donated $100 or more. Total funds raised was $6,600. This followed a similar challenge and response in 2020.

The funds will go into the lake association's Water Quality Fund. In the past, this money has been used for a variety of projects including rain gardens, stormwater ponds, carp management, and aquatic invasive species prevention. In nearly every case the lake association and its partners have used the funds as match for grants, multiplying their cash by 4x to 10x.

Some of the money raised by the Martin Lakers is being used as matching funds toward a new grant secured from the Anoka County Aquatic Invasive Species Prevention Program for radio tagging carp. Linwood, Typo, and Martin Lake are each receiving $3,000 for carp management from the AIS Prevention Program. The lakes are part of a chain of lakes with active carp management led by the Anoka Conservation District. Carp are being removed where they are abundant, and harmful to water quality and habitat.

Along with matching funds from the Martin Lakers, the grants were supported by $750 in matching funds from the Linwood Lake Improvement Association and Sunrise River Watershed Management Organization.

Staff Spotlight: Jamie Schurbon

Jamie Schurbon, ACD's Watershed Projects Manager, has lived a rich and varied life. He grew up in rural Iowa, earning his bachelor's degree from Iowa State University before moving to South Carolina to complete his Master's in Environmental Biology. He spent that time studying reptiles and amphibians in and around the Hell Hole Swamp. After school, he held a variety of short term natural resources jobs that took him from the mangroves of the Florida Keys, to the South Dakota Badlands, to coastal barrier islands. Ultimately, he decided to return to the Midwest and started his first full time position as a technician at the Anoka Conservation District.

Because of his diverse experiences with different environments, it makes sense that instead of a single favorite place in Minnesota, Jamie enjoys the variety, including the Boundary Waters lakes, southeast Minnesota trout streams, northern forests, and prairies. Locally, he especially enjoys spending time on and around the Rum River for its good fishing, quality habitat, and because it is a scenic and quiet getaway.

In his time away from work, Jamie enjoys coaching youth baseball, teaching confirmation classes at his church, playing softball, and working on home improvement projects. Some recent projects have included a kitchen renovation and a canoe rack. Jamie never finds himself short of new projects as one project always seems to turn into another. The old copper plumbing from a kitchen remodel, for example, was then crafted into jewelry.

Jamie indulges his love of the outdoors through hunting and fishing and is also a member of a few sporting organizations including the Isanti County Sportsman's Club, where outdoor enthusiasts both promote conservation and enjoy outdoor activities. Jamie, along with his wife and two sons (ages 11 and 14), have even raised ducks every summer for the last four years.

When asked to share a memorable story of local conservation efforts, Jamie had this to say:

"During my 20 years at ACD I've especially learned a lot from the "old timers" who grew up in the area. I find that today's conservation efforts are not all that different from the past, and these efforts do make a difference. For example, Andover resident, WWII veteran, and former teacher Lyle Bradley once described to me how he flew up and down the Rum River corridor to identify feedlots and dumps on the shoreline. The cleanup that followed made a difference and is a testament to what a committed person can do!"

Linwood Elementary School Rain and Pollinator Garden

Turning a problem into a solution with the Linwood Elementary School rain and pollinator garden.

Construction and expansion took place recently at Linwood Elementary School resulting in a larger roof capturing and sending more rain water to an area in front of the school. This small area is surrounded by the building on two sides, the front sidewalk, and the sidewalk to the main entrance. The additional water produced a large deep puddle for several days and a mud pit after water finally infiltrated. There was a need to improve that area for safety and aesthetics especially since it is in front of the school entrance. The solution: a rain and pollinator garden.

The depressed basin provides a micro example of different hydrologic zones and plant communities ranging from upland plants on the perimeter of the area and wetland plants down in the basin. Parent volunteer, Jennifer Braido took the lead to help facilitate and three 4th grade classes learned about rain gardens so they could create a design for the rain and pollinator garden. ACD staff and Jennifer taught 4th graders about hydrologic zones, plant communities, wetland indicator status, plant adaptations including aerenchyma tissue in wetland plant roots and plant's seasonal bloom times. With all this information, the classes choose their favorite plants for different zones of the garden and did some math to determine how many plants they needed. Another parent volunteer, Robb Johnson, and ACD staff worked to increase water storage capacity by installing a French drain which has reduced the time of standing water after a large rainfall. Finally, the 4th graders were out planting their rain-pollinator garden with the upland species along the edges and the wetland species down in the basin. While they were planting, a monarch butterfly fluttered around appreciating this new habitat. An educational sign is posted to highlight the benefits of rain and pollinator gardens to all that pass by the main entrance to Linwood Elementary School.

ACD Staffer Appointed By Governor to Water Advisory Committee

The Anoka Conservation District's Watershed Projects Manager, Jamie Schurbon, has been reappointed by Governor Tim Walz to the Metropolitan Water Supply Advisory Committee (MAWSAC). He was first appointed in 2012 by Governor Dayton. The committee advises the Metropolitan Council on regional water supply management. Topics addressed include groundwater contamination, protecting the Mississippi River as a drinking water source, water infrastructure, and water supply.

The committee represents diverse interests, with Schurbon as the only member from a local natural resources agency. Other members include public water supply managers, county commissioners, and state agency experts on health, pollution, and agriculture. Anoka County Board Chair Scott Schulte noted the need for balanced perspectives in his recommendation of Schurbon, noting Jamie "has an understanding of the need for both natural resources and community growth to support quality of life in Anoka County."

"I appreciate being part of regional efforts," noted Schurbon. "It's impossible to manage most water issues within one city or county. Groundwater, water supply pipes, and waterways all connect across communities."

Lower Rice Creek Stormwater Retrofit Analysis

The Rice Creek Watershed District (RCWD) contracted with ACD to complete a stormwater retrofit analysis for the purpose of identifying and ranking water quality improvement projects throughout select drainage areas to Lower Rice Creek in Anoka County. The report is in final review by the Technical Advisory Committee, and the final report will be completed by July 1st.

A total of 145 projects were identified throughout the 1,115-acre study area and generally consisted of rain gardens, underground sediment collection chambers, and stormwater pond installations or modifications. Potential projects were ranked in order of cost-effectiveness. The report provides a tool for natural resource managers when considering the implementation of projects to improve water quality in Lower Rice Creek.

The project is funded by RCWD and a Metropolitan Conservation Districts Clean Water Fund Accelerated Implementation grant.

Prairie Enhancement at Gordie Mikkelson WMA

There has been a flurry of activity in the Gordie Mikkelson WMA prairies this spring. ACD is working with the MN DNR, Native Resource Preservation, and Linwood Elementary School to enhance 9.3 acres of prairie and add more species of native grasses and wildflowers in the already established windswept prairie. The 840-acre Gordie Mikkelson WMA is ranked as high biodiversity by the MN Biological Survey, and is an example of the mosaic Anoka Sand Plain landscape, containing a diversity of native plant communities including oak woodlands, sedge meadows, wetlands, and swamps. The MN DNR restored three grassland areas in Gordie Mikkelson WMA to native dry prairie. A remaining 9.3 acres are now undergoing restoration/enhancement. The goal is to convert these areas mostly dominated by non- native smooth brome and quackgrass to a dry prairie plant community (UPs13/Southern Upland Prairie System). Native Resource Preservation (NRP) conducted site preparation herbicide treatments in fall 2019 and fall 2020. The MN DNR conducted a prescribed burn in spring 2021 and NRP spread a diverse seed mix following the Rx burn and will follow up with establishment mowing. The already established windswept prairie is near the Linwood Elementary School and along the trail to their School Forest. This location provides a great opportunity to create a diverse prairie for future seed collection. ACD staff and 16 Linwood Elementary School classes planted 28 different species of plant plugs to add diversity and start a seed source that can be collected and spread to other prairies in the Mikkelson WMA.

Lake Water Levels

The Department of Natural Resources collaborates with Anoka Conservation District to collect lake level data from many lakes across the county. This partnership allows ACD to work directly with county residents who volunteer for the lake level program. These volunteers record the lake level from a staff gauge placed in the lake (typically close to their property) weekly. These data are then reported to ACD and the DNR, and are used on the LakeFinder website.

The DNR LakeFinder website is the best means for the public to access available data on more than 4,500 Minnesota lakes relating to fisheries information, lake area and maximum depth, depth maps, lake water levels, water quality and clarity, air photos, and topographic maps. About 1,450 of the lakes have a historical record of more than 100 water level readings.

At the LakeFinder main page, go to "Find a Lake" and search by county, lake name, or 8-digit identification number for any lake. Click on the lake in the Search Results. On the next page, click on Water Levels report in the left hand column.

The Lake Water Level report page contains information from reported data, including:

  • reported historical and current lake levels
  • period of record and number of readings
  • highest recorded lake level
  • highest known lake level
  • lowest recorded lake level
  • recorded range
  • ordinary high water level [also shown as the red line on the 10-year graph]
  • datum
  • benchmarks
  • most recent 10-year graph [X-axis Year tick mark references mid-year]

ACD is currently seeking a volunteer for Peltier Lake. The permanent staff gauge is affixed to the outlet dam and is easily accessible from the Peltier Lake and Rice Creek Boat Launch parking lot. Having consistent data will help keep the DNR's LakeFinder website up to date throughout the summer. If you are interested in volunteering in taking weekly readings at Peltier Lake, you can reach out to Mollie Annen at This email address is being protected from spambots.

Firsts for the Rare Plant Rescue Program

ACD, Critical Connections Ecological Services, MN Landscape Arboretum, and 17 volunteers salvaged 500 State Endangered rubus stipulatus plants from a proposed development site. This was made possible by working closely with the MN DNR Endangered Species Consultant to incorporate the group's permitted salvage plan with the developer's permit to Take Threatened/ Endangered (T/E) Species for development. If T/E species are found on a site, developers are required to apply for a Permit for the Take of Endangered or Threatened Species Incidental to a Development Project which includes compensatory mitigation. For the first time, the DNR also included our group's salvage plan in part of the Take permit. There was a short window of time between the paperwork and the construction to salvage and transplant. Thankfully volunteers showed up to help out despite the 90-degree temperatures. Plants were transplanted into experimental plots at Bunker Regional Park, City of Blaine Pioneer Park, and Lino Lakes Woolan Park. Plants were also taken to the MN Landscape Arboretum where volunteers potted them for safe keeping for future planting. These 200 potted plants will likely be planted into experimental plots in the fall at Bunker Regional Park, City of Blaine Pioneer Park, Lino Lakes Woolan Park, Blaine Wetland Sanctuary and Columbus Lake Conservation Area. This is the first Endangered Species the Rare Plant Rescue Program has salvaged.
