This Total Maximum Daily Load (TMDL) project will develop a TMDL Report and Implementation Plan defining the sources contributing to the impairments and outlining the steps necessary to bring Bluff Creek back to meeting water quality standards.
This project will develop a Final TMDL report and Implementation Plan for the Bluff Creek Watershed. The main outcomes of this project are the development of a Final TMDL Report approved by MPCA and EPA and a Final Implementation Plan approved by MPCA.
This first year of the project will collect available data relevant to the TMDL development, determine the data sets best suited for the TMDL development. Gain a better understanding of the watershed and impaired lakes, and assessment of all potential sources (internal and external) of the causes of lake impairment. EOR will also review the data produced by the MPCA for the impairment assessment for each of the lakes during year 1 of the project.
This project will finalize HSPF watershed model construction by incorporating internal phosphorus loading in modeled lakes, run a suite of implementation scenarios and generate a GenScn project containing model output. The consultant will produce HSPF watershed models that can readily be used to provide information to support conventional parameter TMDLs. The consultant will deliver all modeling files for baseline and implementation scenarios and provide a GenScn project containing model output.
This project will develop and execute three point source related scenarios for the Chippewa River watershed using an existing HSPF watershed model. This project will also support the review of the HSPF Modeling Guidance Document.
This project will complete the development of two watershed HSPF models for the Mustinka River and Bois de Sioux River watersheds. These calibrated and validated executable models will simulate hydrology at the 12-digit HUC subbasin scale.
This project will continue HSPF watershed model construction beyond the initial framework development. The consultant will add representation of point source discharges to the model. The consultant will also compile flow data for the purposes of calibration and validation. Finally, an initial hydrologic calibration will be performed and submitted for approval.
This project will complete spatial and temporal revisions of 6 Hydrologic Simulation Program FORTRAN (HSPF) models, the recalibration and validation of 7 watershed HSPF models, and the revision of the drainage network and point source representation of the Pomme de Terre HSPF model.
This project will complete the final Implementation Plan, semi-annual and final reports and hold project meetings. The Implementation Plan will identify target areas and priorities for implementation strategies to improve water quality for Bluff Creek. This project will build the groundwork so Bluff Creek will meet water quality standards for aquatic life in the future.
This project will provide the monitoring of reaches where there are data gaps, incorporate new data and analyze relevant data, identify pollutant sources, hold a stakeholder meeting, and gather information towards the future development of a Draft Restoration (TMDL) and Protection Plan.
This project will support the monitoring of reaches where there are data gaps, incorporate new data and relevant data, continue identification of pollutant sources, complete load duration curves, coordinate and encourage participation in stakeholder meetings. The information gathered during Phase IIB will be utilized towards the development of a Draft Restoration (TMDL) and Protection Plan (Plan).
