Riverbanks, Lakeshores, and Rain Gardens, Oh My! - It's Been a Busy Spring

Anoka Conservation District staff have had a busy spring providing technical assistance to landowners for projects related to water resources. Inquiries about riverbanks, lakeshores, and rain gardens have been particularly common. In total, technical assistance has been provided to over 40 individual property landowners.

Active erosion is the primary reason that prompts people to reach out for assistance with their riverbanks and lakeshores. ACD staff have expertise in a wide variety of stabilization methods and know what it takes to complete a successful project. For example, stabilization projects typically require a formal design and coordination with a qualified contractor for installation. There are also a number of permits commonly required, which ACD staff have experience coordinating. Thus far in 2020, technical assistance has been provided for 13 riverbanks and 12 lakeshores.

Technical assistance has also been provided for 16 rain gardens so far in 2020. Rain gardens are generally categorized as either rooftop disconnect or curb-cut. Rooftop disconnect rain gardens receive runoff from downspouts. Driveway runoff could also be directed to rooftop disconnect rain gardens via a trench drain.Rooftop disconnect rain gardens can be a great do-it-yourself project. Curb-cut rain gardens direct water from the curb and gutter system into a shallow depression in your yard near the road and are primarily constructed by landscape contractors. Once the rain garden fills (typically 1' deep), the runoff bypasses the inlet so there is no risk of flooding your yard. This allows the 'first flush' to be treated, which typically has the most pollutants.

Available funding can be limited, but it's always a good idea to check because new grants may become available from year to year. If funding is unavailable, ACD staff can minimally provide technical assistance. That process typically begins with a phone call or email to learn about the site. ACD staff then conduct a desktop site assessment using available mapping data and schedule site visits when necessary. ACD will also provide assistance with design and construction management, which are sometimes covered by grants.

If you have questions about your property, please contact us. In addition to assistance with projects related to water resources, ACD staff are also available to assist with habitat restoration projects.

A Decade of Competitive Clean Water Funding: How Do Local Partners Stack Up?

The voter approved Clean Water, Land, and Legacy Amendment increased sales tax in 2010 to create a constitutionally dedicated funding source so we could manage our natural resources for the enjoyment of current and future generations. The funds are distributed through the Clean Water Fund (CWF) to improve surface water and groundwater, the Outdoor Heritage Fund (OHF) to improve habitat, and the Parks & Trails Fund to improve local and regional parks. The amendment expires in 2034, 25 years after it was passed. Of the three funds, the Clean Water Fund is the one most relied on by local government units to implement locally important projects and programs. During the first 10 years of competitive Clean Water Fund awards, 582 local government units submitted 2,064 successful project proposals and secured over $279M in funds to make our water resources better.

In the first decade of Clean Water Fund awards, Anoka Conservation Districts comes in at a respectable 7th of 582. With 18 successful grant applications totaling just under $4M, we've been able to do a lot of work for those who live, work and play in Anoka County. Details of all CWF projects can be found at Legacy.MN.gov.

Of course, that is only a small part of the whole story. ACD works in tandem with many partners wholly and partially within Anoka County who have also been very successful securing CWF funds and putting water management into action. You may have noticed that three of the top ten recipients statewide serve all or portions of Anoka County, including the City of St. Francis and the Rice Creek Watershed District. In total, twelve of the twenty-one cities in Anoka County, along with three of the seven water management entities have all secured CWF funds to manage surface water and groundwater resources. Many of those not listed were critical partners in project funding, installation, and maintenance. We are all working together to ensure our water resources have a bright future.

Outdoor Heritage Funds have also been a critical source of funds to support habitat management in Anoka County, but that's another story.

Buffer Law Update

Erosion along streambanks causes pollution and loss of property for the landowner. Current development practices often leave streambanks bare and without vegetation. These conditions can lead to erosion occurring on the banks since there is no longer plant material holding the soil in place.

ACD is continuing to work with landowners in 2020 to help bring Anoka County into 100% compliance with the State Buffer Law. The law that was passed in 2017 requires a perennial vegetated buffer along waterways across the state:

  • 50' average and minimum of 30' along designated public waters.
  • 16.5' minimum along designated public ditches.

The goal of the law is to improve water quality in Minnesota as these buffers help filter out phosphorus, nitrogen, sediment and other pollutants.

With the growing season underway, ACD staff is actively checking properties for compliance and providing direction to landowners.

As of July 2019, the state was 98% compliant but this is an ongoing effort and will continue to update and develop as local land use changes.

The next phase, includes another professional review of properties throughout Anoka County to identify non-compliant parcels. This review will be based on 2019 aerial photos that will be released later this year.

Take a Kid Fishing

This past weekend (June 5-7) was the MN DNR's annual Take a Kid Fishing Weekend, but if you missed out, it's not too late to introduce a kid to the outdoors! Fishing is a great way to get kids off the couch and outside while also being a great family bonding activity. Kids under the age of 16 do not need a license to fish, and very little equipment is necessary to get started.

Anoka County offers many locations and opportunities to fish from shore, fishing piers, or other structures in all of its regional parks. No boat required! Additionally, the MN DNR's Fishing in the Neighborhood (FiN) program offers easily accessible fishing for kids and families at many other locations. All of the FiN lakes and rivers in Anoka County can be found online at: https://www.dnr.state.mn.us/fishing/fin/anoka.html

Fishing is a relaxing activity that can get kids interested in the outdoors, and teaches skills that can be used for a lifetime of enjoyment. Even if you don't have a boat, you can spend sunny, summer days reeling in supper for the evening, or the "big one" for a picture. Either way lifelong memories will be made.

The fun doesn't have to end with summer! Fishing can be great through the fall and winter from shore, or on the ice. Fall hunting seasons in Minnesota offer up extensive outdoor recreational activity as well, with many publically accessible areas all over the state.

ACD Receives Aquatic Invasive Species Behavior Change Grant through DNR

Anoka Conservation District, in partnership with Anoka County Parks, received a MNDNR behavior change grant in the amount of $4,992.74 to pilot a strategy to reduce the spread of aquatic invasive species. The pilot behavior change intervention strategy will be delivered to the target audience of boaters and anglers through the installation of new boat cleaning equipment at 5 high traffic boat launches and education provided by on-site AIS inspectors. The project will influence positive behavior change in boaters and anglers by removing barriers such as lack of access to tools/equipment for properly cleaning boats/trailers, lack of space to clean boat or pressure caused by high-traffic boat launches, and lack of knowledge of how to use cleaning tools/equipment. We will lay the groundwork by conducting research on baseline boater behavior this summer, install the weed removal stations in spring of 2021, and collect observational data on weed removal station use and commitments to use the stations from boaters throughout the 2021 boating season. The results of the pilot study will be used by the DNR in future AIS behavior change strategies throughout the state.

LCCMR Environmental Education Grant Application

In collaboration with the Metro Conservation Districts, ACD applied for a 2021 LCCMR Environmental Education grant in the amount of $546,000. If funded, the proposed project would influence perceptions, practices, and policies surrounding ecoscaping in the 11-county metro area by launching a multi-pronged outreach campaign, elevating the educational value of high-profile demonstration projects, and engaging local leaders to adopt eco-friendly policies. The proposed project involves a rigorous barriers and benefits analysis using the proven Community Based Social Marketing framework to identify common barriers faced by residents that limit the widespread acceptance and adoption of eco-friendly lawn care practices. The project will promote the benefits of ecoscaping and create a widespread conservation ethic, particularly in suburban Minnesota. This work is important because turf lawns are unsustainable for the long-term health of our waters and wildlife. While eco-friendly lawn care practices are growing more popular, social norms and misinformation hinder widespread adoption of these practices. Only by addressing the public's perception of ecoscaping, the policies related to preserving and restoring native landscapes, and the practices at all levels of the community will we be able to eliminate barriers and motivate large-scale behavior change.

Save Money and Water!

Spring is here. If you have an irrigation system for your yard, you likely already have it up and running or are considering doing so within the next month. Now is the time when you're setting the watering duration and frequency for each zone in your yard. These settings often remain unchanged throughout the season, which typically results in over-watering. Over-watering wastes drinkable water, and assuming you don't have a private well, it also wastes money.

This year, in addition to following city restrictions (e.g. odd/even watering schedules), try actively managing your irrigation controller. Active management consists of adjusting run times based on local conditions. For example, during periods with sufficient rainfall, watering duration and frequency can be reduced. During these times, you can simply turn your irrigation system off. In contrast, during periods of extreme heat and drought, supplemental watering may be necessary. Watch your yard for signs of drought before turning on your irrigation system, and rely on rainfall as much as possible. When you need to use your irrigation system, water your lawn one time or less per week with a good soaking to encourage deeper root growth, and schedule watering times in the morning to reduce evaporation associated with midday heat and wind.

An alternative to active management is a smart irrigation controller. Smart irrigation controllers use an internet connection to actively monitor local precipitation patterns and automatically adjust watering frequency and duration accordingly. Regardless of whether you choose active management or a smart irrigation controller, both are effective options for reducing water use and saving money.

Spurge Euphorbia esula MN Noxious Weed: Prohibited – Control

  • 1-2 foot tall
  • Greenish-yellow flower bracts
  • Simple and opposite leaves
  • A white, milky sap exudes if the stem or leaves are cut
  • Grows in full to part sun in range of soil types and moisture

If you see leafy spurge, please report it on EDDMaps: www.eddmaps.org/

For more information and control methods see:

https://www.dnr.state.mn.us/invasives/terrestrialplants/herbaceous/leafyspurge.html

https://www.mda.state.mn.us/plants/pestmanagement/weedcontrol/noxiouslist/leafyspurge

Biological control is an option for reducing large infestations of leafy spurge. Adult leafy spurge beetles (Aphthona lacertosa) feed on the leaves and lay eggs at the base of spurge plants. Larvae feed on the roots over the winter until they pupate and emerge as adults the following summer.

Sheet Mulching

Sheet mulching – saves time, builds soil, and smothers existing weeds or lawn without using herbicide.

Sheet mulching is an excellent way to convert lawn to garden beds without using herbicides or excessive labor. Meanwhile it can build soil and be accomplished with readily available materials.

Begin by mowing grass or other vegetation in the area you want to convert into a new garden bed. It can be as simple as layers of newspaper or cardboard topped by four inches of mulch to smother grass and weeds underneath. If this is started in the spring, the underlying plants will have died from lack of light and the garden bed will be ready for planting in the fall.A more diverse layering of material will produce a compost that will break down and build your soil. For this, layer:

  1. Soil amendments if soil test results recommend amendments (lime, greensand, etc.). Recommended if you are creating a vegetable garden.
  2. Thin layer of compost.
  3. Wet newspaper or cardboard, 1/4 – 1/2 inch thick.
  4. Thin layer of nitrogen source such as manure.
  5. Layer of straw or leaves (carbon source).
  6. Continue to alternate layers of nitrogen and carbon sources.
  7. End with a top layer of mulch.

This type of bed is finished when these layers have decomposed. It may take the entire growing season to decompose sufficiently. If you start in the spring, the bed will likely be ready to plant in the fall.

Oak Wilt

Oak Wilt is becoming an increasing problem throughout the State and kills off a large number of oaks every year. Even though oak wilt is active in a large area of Minnesota, effective management techniques exist.

Oak wilt in a healthy tree will begin wilting the canopy. This usually starts at the top of the tree and spreads downward. The tree then sheds leaves, which will begin individually wilting at the edges and spread towards the midrib of the leaf or at the leaf tip and wilt towards the stem. A discoloration or streaking of the wood just below the bark may also be present.

In Red Oaks, the deterioration process can take as little as 4 weeks. In White Oaks, the disease may come back every year but death of the tree could take up to 5 years or longer after the initial symptoms appear.

Healthy oak trees are usually infected by the fungus's ability to move underground through the roots of nearby trees that have grafted together. In general, trees more than 50 feet apart are less likely to be infected through grafted roots. Sap beetles also transport the disease above ground by moving from an infected tree to a healthy one.

Stopping the spread of oak wilt is possible. Breaking root connections between closely spaced oaks will reduce the chance of the disease spreading from infected trees to nearby healthy ones. This takes a specialized piece of equipment and can be difficult to achieve. This is way preventing infection in the first place is the recommended best management practice.

Even though the nice weather makes you want to head outside and work on your property, you should avoiding pruning and wounding healthy oaks in the spring and summer. Between April and July, oak trees are at a much higher risk of infection by sap beetles who are attracted to fresh wounds in the bark of oak trees and may be carrying the fungus. Oak trees should be assessed for storm damage and any wound should immediately be sealed with a water-based paint of another type of plant sealer.

Other techniques to stop the spread of oak wilt include; avoid moving firewood from known infected areas, timely removal and disposal of infected trees, and the use of fungicide when necessary. Many times multiple approaches are necessary to slow or eradicate the problem. Meeting with a local tree care providers can help create a management plan that will be effective on your property.

If you have more questions or are concerned about Oak Trees in your area, contact a local professional to inquire about what can be done on your property. Early detection is still the best method of control.

Trim Oak Trees now to Prevent the Spread of Oak Wilt


Oak wilt is caused by the fungus Ceratocystis fagacearum. Oak wilt can be spread in two ways: 1) fungal spores travelling tree to tree through grafted roots, and 2) fungal spores spread by sap beetles that fly from infected trees or wood to healthy trees. The beetles are attracted to fresh wounds in healthy trees, and these wounds offer an introduction point for the fungus.Trimming or cutting healthy oaks from the months of November through March helps to prevent fresh wounds in healthy trees when the beetles are active. Trimming away dead and dying branches during this period can help prevent oak wilt spreading from neighboring areas to your trees. If your oak trees still need trimming before this spring, be sure to do it before the end of March. April 1 through July 15 is considered the high risk period, and all trimming of oaks should be avoided. July 15 through October 31 is considered low risk, but spread is still possible. Red oaks and pin oaks are especially susceptible to oak wilt, and once infected, a healthy tree is killed within ​months.

Unfortunately, oak wilt is very common in Anoka County. More information on prevention of the disease in your yard can be found at https://extension.umn.edu/plant-diseases/oak-wilt-minnesota
