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 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 Minnesota Soil Survey is an ongoing effort by the Board of Water and Soil Resources (BWSR) in cooperation with the U.S. Department of Agriculture's Natural Resources Conservation Service (NRCS) that is systematically collecting and mapping data pertaining to soil types and other soil properties in each county of the state. Soils data is used by governments, farmers, and other businesses for a number of purposes from protection and restoration of soil, water, wetlands, and habitats to agricultural soil management to building construction.
