Currently, over 235 miles of open ditch are under the jurisdiction of the Brown County Ditch Authority. A majority of Brown County public ditches drain into large, impaired rivers including the Minnesota River (Turbidity), Cottonwood River (Turbidity/Fecal Coliform), Little Cottonwood River (Turbidity/Fecal Coliform) and Watonwan River (Turbidity/Fecal Coliform). Thus far the Brown County Drainage Authority has been inventorying ditches as requested for repair by residents in the ditch system.
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 sixth largest fresh water lake in the United States, Lake of the Woods has sustained significant shoreline erosion through a number of high water events, high inflows from the Rainy River, sustained strong NW winds, and erodible soils on the southern shore. This project implements strategies to protect and enhance private shoreline on the lake by addressing long-term shoreline management.
The Greater Blue Earth River Basin Alliance (GBERBA) along with Soil and Water Conservation Districts, Counties, landowners, and drainage authorities in the ten member counties will install conservation drainage practices to improve water quality. 103E drainage systems with documented sediment or water quality issues are the focus with the goal of installing 52 practices such as improved side inlets (grade stabilization structures), alternative tile inlets, denitrifying bioreactors, saturated buffers, storage wetlands and others.
The goal of this project is to develop a Roseau Lake Water Quality Improvement Report that will include a prioritized, targeted, and measurable implementation plan that will improve water quality in the Roseau Lake watershed. The project will result in development of site specific implementation actions through use of the Prioritize, Targeting, and Measuring Application (PTMApp) and the Drained Wetland Basin Inventory terrain analysis methods.
Approximately 70 percent of all Minnesotans rely on groundwater as their primary source of drinking water. Wells used for drinking water must be properly sealed when removed from service to protect both public health and Minnesota’s invaluable groundwater resources. The Minnesota Department of Health protects both public health and groundwater by assuring the proper sealing of unused wells.
Clean Water funds are being provided to well owners as a 50% cost-share assistance for sealing unused public water-supply wells.
Lake of the Woods (LOW) is a resource with local, regional, state, and international significance and is the second largest lake in Minnesota. Over the past three decades the Warroad River Harbor in LOW has experienced severe sedimentation problems. The sedimentation has led to frequent dredging to remove excess sediment and protect this vital resource. However, it is unsustainable to continue dredging the harbor without also addressing the sources of upstream sediment within the Warroad River watershed.
