Cedar Island, Pike and Eagle Lakes Nutrient TMDL Implementation Plan

The Cedar Island, Pike, and Eagle Lakes Nutrient Total Maximum Daily Load (TMDL) Implementation Plan addresses nutrient impairments in three lakes in the Cities of Maple Grove and Plymouth, Hennepin County, Minnesota, in the Shingle Creek watershed, which is part of the Upper Mississippi River basin. The lakes were placed on the State of Minnesota's 303(d) list of impaired waters: Pike in 2002, Cedar Island in 2004, and Eagle in 2008. Each was identified for impairment of aquatic recreation. Eagle Lake is a highly used regional recreational lake with opportunities for fishing and swimming as well as providing habitat and aesthetic values. Cedar Island and Pike Lakes have more limited public access. Water quality does not meet State standards for nutrient concentrations and thus is not supportive of aquatic recreation. The Shingle Creek Watershed Management Commission (SCWMC) has completed a Total Maximum Daily Load (TMDL) analysis for the Minnesota Pollution Control Agency (MPCA) to quantify the phosphorus reductions needed to meet State water quality standards for nutrients in Cedar Island (27-0119), Pike (27-0111-02), and Eagle (27-0111-01) Lakes (see Figure 1) in accordance with Section 303(d) of the Clean Water Act. The TMDL and Implementation Plan were prepared in cooperation with the Cities of Maple Grove and Plymouth and with review by Hennepin County and the Minnesota Department of Transportation (Mn/DOT). The final step in the TMDL process is the development of an Implementation Plan that sets forth the activities that will be undertaken to reduce phosphorus loading to the three lakes. This Implementation Plan provides a brief overview of the TMDL findings; describes the principles guiding this Implementation Plan; discusses sequencing, timing, lead agencies and organizations; and describes the proposed implementation activities.
