Meadow Lake Nutrient TMDL Implementation Plan

The Meadow Lake Nutrient Total Maximum Daily Load (TMDL) Implementation Plan addresses nutrient impairments in Meadow Lake (27-0057), in the City of New Hope, Hennepin County, Minnesota, in the Shingle Creek watershed, which is part of the Upper Mississippi River basin (see Figure 1). The lake was placed on the State of Minnesota's 303(d) list of impaired waters in 2002 for impairment of aquatic recreation. Meadow Lake is a small, shallow urban lake with a surface area of about 11.8 acres and a fully developed watershed of about 103 acres. The lake is impaired by high concentrations of total phosphorus resulting in severe algal blooms, with summer average total phosphorus concentrations ranging from approximately 200 μg/L to over 250 μg/L in the years in which measurements were taken. For comparison, the numeric standard for Meadow Lake is 60 μg/L or lower. 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; describes the proposed implementation activities; and discusses sequencing, timing, and lead agencies and organizations for the activities.
