Water is pumped to the Highway 100 drainage system, which ows north and ultimately discharges to Minnehaha Creek. 1988 DNR permit allows treatment of the lake with aquatic herbicides and algaecides. Treatment for lamentous algae occurs annually. 2009 The Metropolitan Council gives the lake a letter grade of "D" for water quality, describing it as severely impaired. Historical data shows the lake to be highly eutrophic—having excessive nutrients (primarily phosphorus), which can lead to algal blooms, lack of oxygen, and turbidity. 2013 Melody Lake is treated for submerged aquatic vegetation (invasive Eurasian watermilfoil ) and algae (both lamentous and planktonic). 2015 Aeration system, purchased and installed decades earlier by the Friends of Melody Lake group, is shut off and abandoned in place when the group elects not to pay for the service. 2015 General submerged plant treatments stop with the implementation of Edina's Lakes and Ponds policy, which prioritizes treatment based on a series of factors, including water body size, level of impairment, citizen involvement, and public use. 2016 A lake-level management plan is developed by the City of Edina to dene the circumstances under which Melody Lake will be pumped. According to the plan, a water level greater than 887 feet will trigger pumping until the elevation is lowered to 886 feet. 2018-2022 The City of Edina conducts aquatic plant surveys. Nymphaea odorata, known as North American white water lily or pond lily, is found in each survey. This is a plant with large, fragrant, white owers and at, round leaves (up to 10 inches across) oating on the water's surface or just beneath. Flowers open early in the morning and close about noon. 2019 Curly-leaf pondweed found and treated in seven locations; no curly-leaf pondweed was found in the lake in no curly-left pondweed was found in the lake in 2018, 2020, or 2021. 2021 The City of Edina completes shoreline restoration at Melody Lake Park, adding a native plant buffer to stabilize the shoreline, provide wildlife habitat, and manage invasive plants. The restoration opens views and makes it easier to access Melody Lake. A rock landing was added at the shoreline for year-round use. 2022 The City of Edina conducts an aquatic plant survey. Curly-leaf pondweed is found and treated. 1995 Friends of Melody Lake, an informal lake group, organizes. 1986 Melody Lake treated for excessive algae. 2016 Friends of Melody Lake ofcially incorporated Melody Lake, a landlocked basin, is located just west of Highway 100 and north of Benton Drive. Water levels within the lake are controlled by a pump installed to maintain a consistent water elevation (approximately 887 feet). This helps reduce the ood risk to nearby homes. A 4-acre park with benches surrounds Lake Melody, offering visitors a quiet place to walk and spot wildlife. Motorboats are not allowed, except for emergency rescue or maintenance.

Invasive plant species within the lake are shown above. Curly-leaf pondweed an be harmful to overall lake health. The invasive plant grows under the ice during the winter and is generally the rst pondweed to come up in the spring. It dies in late June and early July, much earlier than other native species. As curly-leaf pondweed decays, phosphorus is released into the water, fueling algal production and depleting oxygen. Eurasian watermilfoil is a rooted, submerged aquatic plant. Like curly-leaf pondweed, it outcompetes native plants and does not provide suitable shelter, food, or nesting habitat for native animals. Aquatic PlantsWater Quality Eurasian watermilfoil Water quality data for 2009 and 2010 was collected by the Met Council's Citizen-Assisted Monitoring Program (CAMP) and made available by the Minnesota Pollution Control Agency. Summer-average highs and lows of water quality parameters over those years are provided above. The available data shows that Melody Lake fails to meet the state's goals for water quality within shallow lakes. Elevated total phosphorus levels promote algal growth, which reduces water clarity.
