The Clay County Drainage Site is designed to evaluate the environmental impact of both surface and subsurface drainage from agricultural fields. This site includes six subsurface plots and one surface runoff plot, each approximately 24 acres in size. Monitoring stations are fully automated and each individual plot is monitored separately.The soils and topography across this demonstration site are virtually identical and represent field characteristics common in the most productive agricultural areas of the Red River Valley.
The goal of this project is to complete the construction, calibration, and validation of a Hydrological Simulation Program FORTRAN (HSPF) watershed model for the Otter Tail River watershed. The contractor will produce an HSPF model that can readily be used to provide information to support conventional parameter Total Maximum Daily Load (TMDL) Studies. The model will generate predicted output for hydrology, sediment, nutrients, and dissolved oxygen that is consistent with observed data.
The goal of this project is to construct, calibrate, and validate a Hydrologic Simulation Program FORTRAN (HSPF) watershed model for the Otter Tail watershed. The contractor will produce a HSPF watershed model application(s) that can readily be used to provide information to support conventional parameter Total Maximum Daily Loads (TMDLs). The contractor will clearly demonstrate that this model generates predicted output timeseries for hydrology, sediment, nutrients, and dissolved oxygen that are consistent with available sets of observed data.
