Best Practice Action Detail

We currently are working with watershed districts to implement several plans. Most notably, Riley Creek is near delisting and has experienced significant increases in water quality. Will definitely be delisted in next 10 years.

Plymouth has several TMDLs for the waterbodies throughout the community. We incorporate the strategies outlined in each TMDL and associated watershed restoration and protection strategy (WRAPS) into the Surface Water Management Plan. To complete the goals, we partner with the Bassett Creek Watershed Management Commission, Elm Creek Watershed Management Commission, Shingle Creek Watershed Management Commission, Minnehaha Creek Watershed District, Hennepin County and State of Minnesota (MPCA/BWSR).

The City of Brooklyn Center has worked with the Shingle Creek & West Mississippi Watershed Management Commision TAC and neighboring communities on the Shingle Creek Chloride TMDL. Improved practices for applying road salt have been made and the TAC just completed a 5-five year review of practices. The City has also worked with the watershed and Twin Lake and Ryan Lake TMDL and a 5-year review has been conducted as well.

Miller creek has a TMDL for temperature. As developments are done in the watershed the stormwater engineer works to insure there are BMPs in place to help reduce temperature.
There are 11 draft TMDLs the MPCA is working on and should be finalized in the near future, 7 for Bacteria Impairments and 4 for Total Suspended Solids (TSS). Also, the city is part of a team that has been working with the MPAC to insure there is a workable solution to the impairments and finalize the TMDLs.

The Bassett Creek Watershed Management Commission (BCWMC), of which Golden Valley is a member, has a Total Maximum Daily Load (TMDL) plan for Sweeney Lake. The Main Stem of Bassett Creek was included in the Minnesota Pollution Control Agency (MPCA)’s Upper Mississippi River Bacteria TMDL and Protection Plan which was approved by the United States Environmental Protection Agency in 2014 and addresses the impairment due to fecal coliform. TMDL plans are carried out through the BCWMC’s and individual member cities’ Capital Improvement Programs and Surface Water Management Plans.
All members of the BCWMC meet on a monthly basis to make sure TMDL implementation plans are being carried out. Golden Valley residents provide funding for BCWMC projects, including TMDL plans, through taxes collected by Hennepin County.

The City of Maplewood in partnership with the Ramsey Washington Watershed District and other stakeholders have been working to decrease the Nitrogen and phosphorus loads in the Phalen-Casey chain of lakes. The city and their partners have been working on projects to meet these nutrient load reduction goals.

There has also been projects done that help determine the amounts of runoff entering Wakefield Lake and what can be done to prevent this.

Minnehaha and Richfield-Bloomington watershed districts have general chloride and phosphorus reductions plans and TMDLs. No bodies of water in Richfield are on the state's impaired waters list.

A small part of Richfield is part of the Nine Mile Creek Watershed District. The watershed district published a TMDL report in 2010 stating that cities must reduce salt application rates by 62%. The first step was staff training that was provided by the watershed district. From there the City made the following changes to reduce the amount of salt applied to streets:
• Calibration of salters
• Apply salt according to pavement temp
• Using alternative types of salt

The City of Victoria has implemented a TMDL plan for four of its lakes. Lake Wasserman, Lake Virginia, Tamarack Lake, and Stieger Lake all have TMLD plans and the City works with the Watershed District to make sure it the TMDLs implementation plans are being applied.

The City is part of the Coon Creek Watershed Restoration and Protection Strategy (WRAPS) TMDL and will be implementing a TMDL plan as part of its current MS4 permit update.

Both the Bassett Creek and Shingle Creek Watershed Management organizations, of which Crystal is a member, have TMDL plans.

Detroit Lakes is in the midst of implementing the St. Clair Lake TMDL. We have a new $35 Million wastewater treatment plant, new MS4 permit that requires benchmarks to meet TMDL.

Mankato pursues a TMDL (total maximum daily load) plan for the lower Minnesota River as part of an overall Stormwater Pollution Prevention Program.

Completed and Ongoing. The City operates with several TMDL implementation plans.

The City is working with partners including CRWD, Roseville and Falcon Heights to implement the Como Lake TMDL Implementation plan.
