This project will conduct a 2017 revision of the South Fork Crow River, North Fork Crow River and Sauk River Watershed Hydrological Simulation Program FORTRAN (HSPF) models and review of the Pine River Watershed HSPF model.
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.
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.
