What's being done
Starting in 2011, the Upper Big Sioux River watershed, along with three adjacent major watersheds located in the Missouri River Basin, will be starting the MPCA’s Major Watershed Restoration and Protection Project (MWRPP) process. Data collection, assessment, and implementation will occur over 10 years.
Each project begins with intensive monitoring where biological data is collected along with physical and chemical data of streams and lakes in selected watersheds. There are 138 proposed stream sites to be sampled for biological data, 23 stream sites for water quality and one site for fish tissue.
MPCA's watershed approach: Since 2007, the MPCA and its partners have begun implementing a 10-year rotation for watershed restoration plans to address Minnesota's waters at the major watershed level.

Restoration and protection
The restoration and protection process
The MPCA and partner organizations evaluate water conditions, establish improvement goals and priorities, and take actions designed to restore or protect water quality on a 10-year cycle.
Monitoring and assessment
Projects in this watershed to test water quality conditions and determine whether our lakes, rivers, and wetlands are meeting state water quality standards. [More info]

Data available for this watershed
Lakes and stream segments with condition and monitoring information
Lakes and streams are divided into "assessment units" for monitoring.
Impairments in this watershed listed by lake or stream segment
Generally, a waterbody has an impairment when it exceeds a particular pollutant standard.
Strategy development projects
Projects in this watershed that establish federal- or state-required plans for restoring water quality for impaired waters, or protecting high-quality waters. [More info]

Implementation activities
Projects in this watershed to put water restoration or protection measures in place, ranging from best management practices to reduce runoff from fields or streets, to fixes to wastewater treatment facilities, to education activities for citizens and landowners. Implementation projects are supported by local, state and federal government sources, including Minnesota's new Clean Water Fund.
Our partners in the watershed are continually involved in these kinds of activities. See Contacts tab.

Many of Minnesota’s lakes and streams do not currently meet water-quality standards because of pollution such as excess sediment or nutrients, bacteria or mercury. These waters are considered “impaired.” For more information, visit the impaired waters page.
