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 better target restoration activities in the Cannon River watershed via a paleolimnological study of a selected set of the lakes addressed in the Total Maximum Daily Load (TMDL) for the watershed. The goals are to better constrain lake phosphorus budgets, and determine the magnitude of ecological change experienced by a range of lake types.
Consistent with the implementation recommendation of the Total Maximum Daily Load Study , the goal of this project is to install 30 grade stabilization structures along Polk County Ditch 80 to reduce sediment loading by 270 tons per year. Polk County Ditch 80 contributes a large amount of sediment to the Sand Hill River which currently does not meet state water quality standards for sediment.
