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.
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.
