About Plymouth Creek
Plymouth Creek originates upstream of Medicine Lake in western Plymouth and drains large portions of south and central Plymouth. It flows generally east and south, relatively parallel to Highway 55, until it reaches the southwest bay of Medicine Lake. The area tributary to the creek prior to its discharge into Medicine Lake is approximately eight square miles. Plymouth Creek flows through a large wetland complex near Medicine Lake prior to entering Medicine Lake.
Plymouth Creek is included on the Minnesota Pollution Control Agency's (MPCA) Impaired Waters list. Impaired uses include aquatic life, due to chloride levels, and aquatic recreation, due to fecal coliform bacteria. Plymouth Creek was included in the MPCA's Upper Mississippi River Bacteria TMDL and Protection Plan, which was approved by the United States Environmental Protection Agency in 2014.
