This project will be a complete TMDL report for the Biota and Bacteria (E. coli) impairments for the Ann River Watershed. The water bodies associated with these impairments will then be removed from the MPCA’s impaired waters list, and implementation activities to restore the water bodies will begin.
The Snake River Watershed Management Board (SRWMB), working in concert with other local governmental units in within the watershed, will assist the MPCA, the project consultant, and other members of the Snake River Watershed Total Maximum Daily Load (TMDL) technical team in the completion of tasks associated with this TMDL project. SRWMB, with assistance from members of the technical team (Kanabec Soil and Water Conservation District (SWCD), Pine SWCD, Aitkin SWCD, and Mille Lacs SWCD) will provide the services to complete this TMDL project.
This project will provide baseline data through water monitoring, recording and analyzing the results of six unassessed rivers/tributaries, three unassessed lakes and five storm water outlets in the city of Mora which drain to the Snake River; promote and implement approved BMP’s.
The Drinking Water Contaminants of Emerging Concern (CEC) program identifies environmental contaminants for which current health-based standards currently do not exist or need to be updated, investigate the potential for human exposure to these chemicals, and develop guidance values for drinking water. Contaminants evaluated by CEC staff include contaminants that have been released or detected in Minnesota waters (surface water and groundwater) or that have the potential to migrate to or be detected in Minnesota waters.
This project will complete a Total Maximum Daily Load (TMDL) study for the impaired reaches of the Snake River Basin. The project includes development of a Generalized Watershed Loading Function (GWLF) model for nutrient sources and Total Suspended Sediment (TSS), a spreadsheet version of a BATHTUB model of lake response for four lakes, and a bacteria source assessment. Wenck will also provide all stream channel data as a spreadsheet and locational database.
This phase of the project will complete a TMDL for the impaired reaches of the Snake River Basin. The project includes development of a Unit Area Load model for nutrient sources, a spreadsheet version of a BATHTUB lake response for four lakes, and a bacteria source assessment. Contractor will also provide all stream channel data as a spreadsheet database and in GIS.
