This project will establish a framework with County, Soil and Water Conservation District and watershed staff that will outline their involvement throughout the development of the Watershed Restoration and Protection Strategy (WRAPS) for the Cottonwood River and Redwood River watersheds.
The Drinking Water Contaminants of Emerging Concern (CEC) program identifies environmental contaminants for which current health-based standards currently do not exist or need to be updated, investigate the potential for human exposure to these chemicals, and develop guidance values for drinking water. Contaminants evaluated by CEC staff include contaminants that have been released or detected in Minnesota waters (surface water and groundwater) or that have the potential to migrate to or be detected in Minnesota waters.
This project addresses five reaches of the Minnesota River that have aquatic recreation impairments as identified by high concentrations of E. coli. The project will describe the water quality impairments, complete pollutant source assessments, establish loading capacities and allocations for the impairments, and develop implementation strategies.

This project will update sediment Total Maximum Daily Loads (TMDLs) for 60-64 impaired stream reaches and provide a final TMDL report. The report will address sediment and turbidity impaired streams in the Minnesota River Watershed. TMDLs will describe the impairment in each water body and water quality targets, and will include a discussion of pollutant sources, supporting report components that document assumptions and methodologies, and TMDL equations with completed load allocations, wasteload allocations, and margin of safety for each impairment.
The goal of this project is to refine the nutrient and algae simulation in the Minnesota River basin using all relevant available sources of information. The outcome of this work order is a revised Hydrological Simulation Program – FORTRAN (HSPF) watershed model application for the Minnesota River basin that correctly represents nutrient sources and algae.
In 2017 and 2018, Redwood-Cottonwood Rivers Control Area (RCRCA) will collect water chemistry samples from the 10 lakes and 24 stream sites identified in the Redwood and Cottonwood River watersheds. Six samples will be collected at 10 lakes from May through September in 2017; five samples will be collected at 5 lakes in 2018 from May through September. Eleven samples will be collected at each of the 24 stream sites following the Basic Regime in 2017. Sixteen samples at each stream site will be collected in 2017 and 2018 following the E.coli monitoring regime.
