Water Quality in our Lakes and Streams
|
Water quality in the lakes and streams in the two watersheds is typical of urban waters in the Twin Cities metropolitan area, and is dominated by watershed runoff. The Commissions monitor flow and water quality in the streams in the watersheds and in the outfalls to the Mississippi River, as well as lake water quality, fish communities and aquatic vegetation. Results are published in an annual Water Quality Report.
2017 Water Quality Report and Appendices 2016 Water Quality Report and Appendices 2015 Water Quality Report Submersed Aquatic Vegetation (SAV) Management Policy The Shingle Creek Watershed Management Commission works in partnership with its member cities, Hennepin County, MnDOT, property owners, and other parties to protect and improve lakes, wetlands, and streams in the watershed. The Commission’s goal is to meet State of Minnesota water quality standards and to promote a healthy and diverse community of native aquatic organisms and vegetation. To achieve that goal the Commission may periodically partner with one or more member cities to undertake lake internal load management projects, such as alum treatments or rough fish management. SAV Policy Thirteen of the 16 lakes were originally listed as Impaired Waters due to excess nutrients, and TMDLs and Implementation Plans have been approved for all 13 of the lakes. Three of those lakes now meet state standards and have been "delisted" on the pending 303(d) list of Impaired Waters. Shingle Creek is Impaired for chloride, low dissolved oxygen, aquatic life, and E. coli bacteria. Bass Creek is Impaired for chloride and aquatic life. |
The Clean Water Act requires all states to evaluate the conditions of their lakes, streams, and wetlands, and to establish standards for surface water quality. Waters that do not meet a state's standards must be included on the state's 303(d) List of Impaired Waters. When the waters are improved and meet water quality standards, they are eligible for "delisting."
The Minnesota Pollution Control Agency administers the Clean Water Act in Minnesota. Find out more about the state's Impaired Waters program here. |
