This project will complete a Watershed Restoration and Protection Plan for the Lower St. Croix River that provides quantitative pollutant load reduction estimates and a set of pollutant reduction and watershed management strategies to achieve water quality standards for all impairments within the watershed, and that are understood and adoptable by local units of government and other stakeholders.
This project will complete spatial and temporal revisions , recalibration and validation of 7 watershed HSPF models. These fully functioning calibrated validated executable models will simulate hydrology, sediment (sand, silt, and clay), temperature, phosphorus, nitrogen, dissolved oxygen, biochemical oxygen demand, and algae at the 12-digit HUC subbasin scale (or finer).
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 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.
This project will provide modeling services to support the completion of the Typo Lake and Martin Lake Excess Nutrients TMDL report. A Total Maximum Daily Load (TMDL) report quantifies pollutant levels, identifies sources of pollution, and proposes ways to bring water quality back to an acceptable level.
Within the Valley Branch Watershed District (VBWD), there 47 Minnesota Department of Natural Resoruces (MN DNR)-protected basins with surface areas larger than 10 acres and three DNR-protected streams. Only Sunfish Lake is currently on MPCA’s 303(d) Impaired Waters List for aquatic recreation due to excessive nutrients. However, Bay Lake, Eagle Point Lake, Downs Lake, Goose Lake, Kramer Pond, and Echo Lake are on the draft 2012 Minnesota 303(d) Impaired Waters List for aquatic recreation due to excessive nutrients, and Kelle’s Coulee is on the draft 2012 list due to bacteria.
