Minnesota's Impaired Waters and TMDLs
This TMDL project addresses the nutrient impairments within Lura Lake. The TMDL study is currently underway and is being developed by the Minnesota State University Mankato -Water Resources Center. A stakeholder committee representing urban, agriculture, watershed projects, government, and citizens is currently under development.
This TMDL is part of a nationwide effort under the Clean Water Act to identify and clean up pollution in streams, rivers and lakes. The federal Clean Water Act requires states to adopt water quality standards to protect the nation’s waters. The Clean Water Act also requires states to assess all waters of the state and develop cleanup plans for waters that do not meet water quality standards (TMDL)
- The project work plan has been developed.
- Further assessment and monitoring is taking place along side analysis of existing data and background conditions.
- The Water Resources Center is currently drafting portions of the TMDL.
- A draft of the report will be out in early 2011.
Map and location
Lura Lake is located in the Le Sueur watershed in the Minnesota River basin. For additional information, see the Redwood-Cottonwood Rivers Control Area (RCRCA) website or the MPCA's Impaired Waters Viewer.
