There are two main goals of this Cedar Basin HSPF project,
A. Overall development of the HSPF model in the Cedar Basin of Minnesota; and
B. Shell Rock River nutrient, DO , impairment modeling and TMDL completion.
The MPCA has selected the Soil and Water Assessment Tool (SWAT) watershed model to simulate watershed hydrology and water quality to assess various restoration scenarios in the Little Cannon River watershed. The SWAT model is an important tool in developing an understanding of existing conditions and simulating conditions under various management scenarios to inform the development of implementation strategies and plans to restore and protect streams and lakes.
The goal of this project is to leverage the existing Hydrological Simulation Program FORTRAN (HSPF) model application that has been calibrated and validated for the Shell Rock River Watershed to assist with wastewater permitting. The contractor will deliver all modeling files and a final technical memorandum outlining the scenarios developed, how the scenarios are represented in the model, and the impact these scenarios have on water quality at specified locations for parameters of concern as described below.
This project will complete an extension of the Shell Rock River Hydrologic Simulation Program FORTRAN (HSPF) watershed model application through the year 2018. Compliance scenarios will be executed to address potential expansion of discharges from the Albert Lea Wastewater Treatment Plant (WWTP).
