The purpose of this project is to develop a framework to implement best management practices (BMPs) on ditches in headwater areas utilizing a partnership between drainage staff and the Greater Blue Earth River Basin Alliance (GBERBA). By replacing failing side-inlets with an alternative design, we can make strides towards our water quality and water quantity goals. The alternative inlets serve to prevent sediment and phosphorus from washing downstream and the design can also alleviate peak flows by temporarily storing stormwater.
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.
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.
