Crystal Lake Nutrient TMDL Implementation Plan FINAL

The Crystal Lake Nutrient Total Maximum Daily Load (TMDL) Implementation Plan addresses nutrient impairments in Crystal Lake, which is located in the City of Robbinsdale, Hennepin County, Minnesota, in the Shingle Creek watershed. 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 Crystal Lake (27-0034) (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 two cities (Robbinsdale and Minneapolis) with land located in the Crystal Lake subwatershed and with review by Hennepin County. 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 lake. 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 other implementation general strategies; and describes the proposed implementation activities.
