Lakeshores and Lake Health
Shorelines
Shorelines can have direct impacts on lake health. Shorelines that only contain mowed grass can lead to erosion, excess nutrients, and overall poor lake health. Adding a shoreline buffer full of native plants helps lock soil in place and soak up excess nutrients before it can enter the lake. Shoreline buffers also provide habitats for diverse wildlife including pollinators. Learn the details of how shorelines impact lake health and how you can help in this video by Anoka Co. Water Resource Outreach Collaborative.
View video summary
An animated video from the Anoka Conservation District about how lakeshore owners can protect the health of their lake.
It explains that Minnesota’s many shallow lakes are especially sensitive. Runoff from yards and streets carries extra nutrients that feed algae, and when shoreline and aquatic plants are removed, the shore erodes and the water turns murky. Invasive species like Eurasian watermilfoil, zebra mussels, and invasive carp add to the harm.
The video then walks through steps lakeshore owners can take:
- Use lake-friendly lawn care: rain barrels, rain gardens, picking up pet waste, maintaining septic systems, and keeping grass clippings out of the lake.
- Fix erosion with native plants, trees, and shrubs whose roots hold the shore in place, rather than relying on rock riprap alone.
- Plant native buffers along shoreline that isn’t used for water access. Buffers filter runoff, provide wildlife habitat, and discourage geese.
- Avoid clearing aquatic plants like water lilies, which hold the lakebed in place and shelter fish, frogs, and turtles.
- Watch for aquatic invasive species and report new infestations.
It closes by noting that a healthy shoreline can still include a dock and lawn space, and that lakes are healthiest when neighbors work together.
Grants
Shoreline buffers are commonly eligible for grant funds from our cost share program. If you own lakeshore property and are interested in restoring your shoreline, learn about our cost share program at our website. Projects can be installed on all types of properties, not just lakeshores. Learn more about other environmentally friendly projects that are eligible for grant funds at our website.
