Medicine Lake
Medicine Lake is a 936 acre (379 ha) heavily urbanized lake with a maximum depth of 49 feet (15m) and a mean depth of 16 ft (5m). The lake is located in Plymouth, MN, within Hennepin County. Lake water quality is poor due to high nutrient levels, and the lake is classified as an impaired resource by the Minnesota Pollution Control Agency.


To address the Medicine Lake nutrient issue the new Lake Access EMPACT project is doing the following:

  • A community experiment: Monitoring urban runoff under normal and phosphorus-free fertilization regimes.

  • Real-time monitoring:
    We have placed a RUSS unit on to Medicine Lake to collect real-time lake data.

    Stream samplers have been placed in Plymouth and Ridgedale Creeks.
