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 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 purpose of this project is to improve understanding of primary productivity in the Red River and the diversity and population structure of the algal communities occurring along the river system. This will be accomplished through taxonomic identification of periphyton and phytoplankton assemblages necessary for characterizing responses to nutrient gradients along the Red River of the North.
International Water Institute (IWI) staff will monitor 24 sites in the Bois de Sioux, Mustinka (2 sites), Buffalo (8 sites), Red Lake (4 sites), Sandhill (3 sites), Thief (2 sites), and Tamarac River (3 sites) Watersheds intensively over a 2 year period in an attempt to collect 25 samples per year at each site. If conditions allow for the collection of all planned samples, 1200 stream samples will be collected over the time period. Monitoring will include field measurements, observations, and at least three photographs during each site visit.
MN Legislative Clean Water Fund funding to engage citizens in local watershed monitoring, work with regional partners to promote understanding and protection of watersheds, and organize and facilitate gathering of scientific data all for the benefit of water quality in the Red River Basin.
The goal of this project is the continued 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. The overall strategy will be used to help establish a path towards achieving the required reductions of turbidity/TSS.
