Ramsey-Washington Metro Watershed District (RWMWD) will improve water quality in Casey Lake and ultimately Kohlman Lake through the installation of approximately 25 rain gardens on priority properties identified as part of the Casey Lake Urban Stormwater Retrofit Assessment completed by Ramsey Conservation District (RCD) in 2011.
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.
The north-central Minnesota counties of Cass and Hubbard share large portions of the Crow Wing River, Leech and Upper Mississippi Watersheds, all of which play an important role in providing clean drinking water to over one million Minnesota residents. Each county assumes the responsibility of inspecting and evaluating the judicial and county ditch systems that drain directly into these watersheds. The two counties together share two judicial ditch systems and combined have an additional 42 ditches within their borders.
As lake-focused development continues these high quality waters will see increasing amounts of land use change. The State Demographer projects that the targeted lake catchments will see population increases of 25-62% within 20 years. Isolating these contributing areas permits the Lake Protection Analysis project to perform multiple GIS analyses to accurately inform water quality discussions. The final framework will allow local water managers to prioritize across their water bodies, target activities to specific subsheds, and develop measurable goals.
This project supports monitoring and assessment activities by MPCA EAO staff and includes lab analysis, equipment, fieldwork, data management, and interpretation expenses associated with monitoring and assessment activities.The ambient groundwater monitoring network describes the current condition and trends in Minnesota's groundwater quality.
The Otter Tail County Community Partners Grant Project will enable community groups to go beyond planning and take action to protect their water resources. This grant program will provide targeted community groups with the means to make positive improvements now and identify high priority projects for future opportunities. Engaging community members in the identification of water protection opportunities with the data in recently completed lake assessment reports will help build connections and foster a stewardship ethic.
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.
