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 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.
The goal of this project is the continued development of an overall strategy for reduction of turbidity/TSS, with sets of sediment reduction initiatives and actions for various sources, to address the Minnesota River Turbidity TMDL and the South Metro Mississippi River TSS TMDL. The overall strategy will be used to help establish a path towards achieving the required reductions of turbidity/TSS.
This project will complete a chloride management plan which will lay out a strategy for addressing chloride impacts to our surface waters for the 7-county metropolitan area. This chloride management plan will satisfy EPA requirements for impaired waters, address waters not yet listed, and develop a strategy to protect waters that are currently meeting the water quality standards.
This project will provide the MPCA and all local partners in the Twin Cities Metropolitan Area (TCMA) the information and tools necessary to improve and/or maintain water quality with respect to chloride for the 7-county metropolitan area during the winter maintenace period.
