The Greater Blue Earth River Basin Alliance (GBERBA) along with Soil and Water Conservation Districts, Counties, landowners, and drainage authorities in the ten member counties will install conservation drainage practices to improve water quality. 103E drainage systems with documented sediment or water quality issues are the focus with the goal of installing 52 practices such as improved side inlets (grade stabilization structures), alternative tile inlets, denitrifying bioreactors, saturated buffers, storage wetlands and others.
Nicollet County is located in south central Minnesota and is bordered on two sides by the Minnesota River. A line of forested bluffs separate the river valley from land that is relatively flat and historically used for agricultural purposes. Approximately 245,000 acres of the County are actively farmed. The 2012 impaired waters list for water bodies located in Nicollet County include the Minnesota River, Seven Mile Creek, Rogers Creek and tributaries to the Rush River.
The lack of sewage treatment in many small communities in Southeast Minnesota is causing surface water and groundwater pollution. Fourteen of these small communities will receive technical assistance provided by this project. These communities have community or individual straight pipes which are discharging raw sewage directly to the environment, surfacing sewage, or have sewage contaminating groundwater.
