Within Whitewater River Watershed, groundwater is the primary drinking water source for both private and community wells. These drinking water aquifers often lack adequate protective layers making them vulnerable to contamination. Unused wells can deteriorate and pose a serious risk to groundwater quality by providing a pathway for contaminants from the surface to easily travel into groundwater. This project will use cost-share funds to incentivize sealing twelve abandoned wells that are contamination risks to vulnerable aquifers.
This grant will fund about 45 projects in High Groundwater Priority areas, High Surface Water Priority area, and/or in sub-watershed with stressed/impaired streams for the four WinLaC planning regions. These practices will reduce overland total nitrogen loading and loading to groundwater; reduce overland total phosphorous and sediment; and increase headwater storage and/or reduce peak flow rates and sediment loading.
The WinLaC Prioritization and Public Participation Project will identify priority water quality issues and concerns for the watershed approach in the Mississippi River - Winona and La Crescent watersheds. Information obtained from this project will help develop the Watershed Restoration and Protection Strategy (WRAPS) Update report as well the WinLaC Comprehensive Watershed Management Plan.
This project will produce a final Total Maximum Daily Load (TMDL) report and Watershed Restoration and Projection Strategy (WRAPS) reports for the Winnebago and Mississippi River – La Crescent watersheds including the drafting of public notice versions of the reports, responding to comments during the public notice period and producing the final TMDL and WRAPS reports.
The Winona County Well Sealing Costshare Program will utilize Clean Water Funds to speed water well sealing in a continuing effort to protect the groundwater aquifers used for drinking water in Southeast Minnesota. Since 1990, 1303 unused water supply wells have been sealed in Winona County with costs ranging from $500-$10,000+ per well.
The Zumbro River watershed HSPF model will be refined to include recent data and information as well as evaluate various management scenarios to inform the most effective actions for reducing sediment and nutrient loading and improving water quality. Specifically, to provide the foundation for the Lake Zumbro Phosphorus Total Maximum Daily Load (TMDL).
