The goal of the project is the development of an overall strategy for reduction of turbidity/TSS, with sets of sediment reduction initiatives and actions for various sources, to address the Minnesota River Turbidity TMDL and the South Metro Mississippi River TSS TMDL.
This project will monitor six sites within the Minnesota River Basin: Hawk Creek near Maynard, Hawk Creek near Granite Falls, Beaver Creek near Beaver Falls, Yellow Medicine River near Granite Falls, Yellow Medicine River near Hanley Falls, and Spring Creek near Hanley Falls. The sites will be monitored according to MPCA’s Major Watershed Load Monitoring (WPLMN) Standard Operating Procedure, which is the procedure being followed for sites currently monitored by the Hawk Creek Watershed Project (HCWP).
This project will complete spatial and temporal revisions , recalibration and validation of 7 watershed HSPF models. These fully functioning calibrated validated executable models will simulate hydrology, sediment (sand, silt, and clay), temperature, phosphorus, nitrogen, dissolved oxygen, biochemical oxygen demand, and algae at the 12-digit HUC subbasin scale (or finer).
This project will continue the offering of low-interest loans to citizens, some of whom may not be able to acquire funding otherwise, for upgrading 50 septic systems to ensure compliance with state rules. Grant funds will be used to administer the low-interest loan program.
The Redwood and Cottonwood River Watersheds have been assessed and many reaches have been impaired for turbidity, bacteria, and low dissolved oxygen. This project will accelerate conservation efforts to reduce overland runoff sediment, bacteria, and nutrient loadings contributing to water quality impairments in targeted subwatersheds.
The Redwood River and Cottonwood River watersheds encompass approximately 2,020 square miles of southwestern Minnesota in the Minnesota River Basin. Land use in these watersheds is mostly agricultural and area geology makes them prone to erosion. Surface water issues within the two watersheds are a concern of local leaders. The counties and Soil and Water Conservation District leaders formed the Redwood Cottonwood Rivers Control Area (RCRCA) Joint Powers Board in 1983 to address sedimentation, water quality and quantity, and erosion issues.
Approximately 70 percent of all Minnesotans rely on groundwater as their primary source of drinking water. Wells used for drinking water must be properly sealed when removed from service to protect both public health and Minnesota’s invaluable groundwater resources. The Minnesota Department of Health protects both public health and groundwater by assuring the proper sealing of unused wells.
Clean Water funds are being provided to well owners as a 50% cost-share assistance for sealing unused public water-supply wells.
