Shingle Creek Chloride TMDL Report

The goal of this TMDL is to quantify the pollutant reductions needed to meet the water quality standards for chloride in Shingle Creek. The Shingle Creek TMDL for chloride is being established in accordance with Section 303(d) of the Clean Water Act, because the State of Minnesota has determined waters in the Shingle Creek Watershed exceed the State established standards for chloride. Shingle Creek has an urban/suburban watershed located in the northwestern portion of the Minneapolis metropolitan region. The Creek is heavily used for stormwater management. The drainage system is composed of Shingle Creek, which is the major waterway, several tributaries, some intermittent streams, and a few man-made ditches. The main stem of Shingle Creek begins in Brooklyn Park in northwestern Hennepin County and flows generally southeast to its confluence with the Mississippi River in Minneapolis. Shingle Creek is formed at the junction of Bass Creek and Eagle Creek, two of the minor tributaries in the watershed. The creek is approximately 11 miles long and drops approximately 66 feet from its source to its mouth. Palmer Lake is the only lake directly on Shingle Creek.
