At last night’s City Council meeting, the City approved a grant from the Board of Water and Soil Resources Clean Water Fund to construct an iron-enhanced and biochar sand filter at the Gardena Avenue storm sewer outlet, which flows into Moore Lake.
This filter will help improve water quality by removing trash, sediment, phosphorus and bacteria from the stormwater run-off before it enters the lake, and is planned for construction in 2022.
Improvement of the water quality at the lake is an important component of the revitalization of Moore Lake Park that is currently being determined by community feedback. Draft designs for Moore Lake Park were created based off of input received at the 2019 Finding Your Fun in Fridley workshops. Draft design concepts include increased planting of native plants to discourage geese, relocating one of the docks, as well as adding a paddle rental kiosk and ADA accessible water access. These proposed improvements will help make the lake more friendly for aquatic recreation.
Now, we want to hear from you! Review the park plans and tell us what you like, what you don’t like, or what you’d like to see incorporated to the future of Moore Lake. You can view all the park plans and submit feedback until April 30: FridleyMN.gov/FindingYourFun-Updates.
Grant application process
Moore Lake is a shallow lake, which makes it especially sensitive to pollution. Moore Lake was listed by the Minnesota Pollution Control Agency as impaired for aquatic recreation because of excess nutrients in 2002. These excess nutrients are due to the stormwater runoff from the surrounding area that enters the lake via the storm sewer system. This stormwater runoff contains nutrient-rich pollutants such as leaves, fertilizer, and sediment that wash off of lawns, driveways, and parking lots when it rains. Similar to how nutrients in the garden make plants grow, nutrients in the stormwater runoff lead to algal blooms. Sampling of the stormwater outlet also shows that, following heavy rain events, the runoff contains bacteria in amounts that can be unsafe for swimming.
The Rice Creek Watershed District and Anoka Conservation District performed a stormwater retrofit analysis of the Moore Lake subwatershed in 2015 to identify how to best address the pollution, and prioritized a filter at the Gardena Avenue storm sewer outlet (the channel under the bridge). In 2020, the City applied for and received a Board of Water and Soil Resources Clean Water Fund grant.
