Diamond Lake TMDL Implementation Projects
Construction of a stormwater treatment facility to treat runoff from 6,500 acre urban and agricultural drainage area in and around the City of Watkins, MN. The result is an annual phosphorus reduction of 796 pounds to Lake Betsy, the Clearwater River, and the Clearwater River Chain of Lakes, as well as an oxygen demand reduction benefit of 10% for the Clearwater River.
This project achieved an estimated annual reduction of 1.1 lbs of nitrogen, 29 lbs phosphorus, and 2669 tons of sediment.
LOCAL LEVERAGED FUNDS
Diamond Lake and its neighboring lakes feature numerous public water accesses, resorts, parks, and trails and are supported by the recreational and aesthetic values that good water quality provides. In 2006, Diamond Lake was placed on MPCA's List of Impaired Waters. Improving water quality in Diamond Lake to meet state standards is a top-ranking priority for the district. The Middle Fork Crow River Watershed District is partnering with the MN DNR and Ducks Unlimited to implement a water level management project for the upstream chain of lakes in 2015 to achieve an estimated phosphorus load reduction of 343 pounds per year. The reduction of phosphorus load outlined in this application will achieve 72 percent of the reduction goal from watershed sources, and 55 percent of the overall reduction goal.
