Lily Lake Stormwater Retrofit Feasibility and Design to Achieve State Water Quality Standards
After nearly a decade of intensive targeting, design and installation of water quality improvement practices, Lily Lake has an improving trend in long-term summer total phosphorous concentrations for the first time since monitoring began in 1985. To date, 36 storm water quality improvement projects have reduced 100 pounds of annual phosphorous discharging to Lily Lake. This project will engage residents and stakeholders in the targeting and design of the final water quality practices to complete the final 45 pounds annual phosphorous reduction necessary to remove Lily Lake from the State of Minnesota impaired waters list.

The project will reduce 595 tons of sediment per year fromentering the Rabbit River. This is 18 percent of the Rabbit River Total Maximum Daily Load (TMDL) goal. It will also reduce peak flows to the ditches by 44% during a 10 yr/24hr storm event.
This project resulted in an estimated annual reduction of 41 lbs of phosphorus and 39 tons of sediment.
