Duck Lake

Located in Eden Prairie, Duck Lake is one of the District’s shallow lakes. Since 2011, it has seen improvement in water quality and met the Minnesota Pollution Control Agency’s clean water standards for several years.

Duck Lake is classified as a “Shallow Lake” by the MPCA. To be considered healthy, the lake must have very low average phosphorus and chlorophyll-a levels and an average water clarity of 1.0 meters (3.3 feet) or greater.

From June through September every year, District staff visit this and other lakes every two weeks to collect water samples and take readings. Samples are sent to a laboratory to be tested for nutrients and other compounds. Staff also measure water clarity by lowering a Secchi disk into the water and measuring how deep it goes before it is no longer visible. The data indicates the lake’s health based on standards set by the MPCA.

Duck Lake - Water Quality Grade

Lake WQ Grade C.png RPBCWD staff assigned this letter grade to the lake based upon how well it is meeting water quality goals. Learn more about lake water quality grades.

Several water quality parameters are monitored for the lake including Total Phosphorus, Chlorophyll-a, and water clarity. The results are compared to standards set by the MPCA. The District also collects data about native aquatic plant populations and invasive species. Learn more in the lake factsheet.
