This project will continue to develop, and calibrate/validate the hydrology of an Hydrological Simulation Program FORTRAN (HSPF) watershed model for the Buffalo River watershed. The consultant will add representation of point source discharges to the model. The consultant will compile flow data for the purposes of calibration and validation. An initial hydrologic calibration will be performed and submitted for approval.
The Buffalo River Watershed Pilot Project is one of two pilots in Minnesota designed to develop a watershed approach for managing Minnesota’s surface waters. The goal of this project is to develop a plan that will guide surface water quality management throughout the watershed.
This project will maximize the utility and usefulness of three HSPF models that have been constructed and calibrated for hydrology. The contractor will identify and reduce parameterization errors in the following three HSPF models: 1) Buffalo River Watershed, 2 ) Thief River Watershed, 3) Bois de Sioux-Mustinka Watersheds. This will result, not only in a better hydrology calibration, but will also improve each of the models’ ability to more accurately estimate sediment and pollutant loads and concentrations.
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.
