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 LeSueur River Watershed is one of the highest nutrient loading watersheds for both phosphorus and nitrogen in the State of Minnesota. The LeSueur River Watershed Restoration and Protection Strategies (WRAPS) Report was completed in August 2015 and further identifies pollutant sources and reduction goals within the LeSueur River Watershed. The WRAPS report highlights the Beauford Ditch watershed and the Madison Lake watershed area amongst the highest sources of nutrient loading to the LeSueur River.
The objective of the project is to develop a targeted stormwater implementation and outreach program focused on non-profit partners. The Nine Mile Creek Watershed District is a 50 square mile fully-developed watershed with 15 major lakes and over twenty miles of creek system. Given that much development in this area occurred prior to the era of stormwater management regulations, runoff from many sites is untreated prior to discharge to downstream water bodies.
