Vegetated buffer and filter strips along waterways is a practice that addresses many surface water concerns. Establishing permanent vegetation along waterways is an implementation priority in the Blue Earth County Water Management Plan and required by local ordinance and Minnesota Rules. Minnesota Shoreland Rules, Chapter 6120 and the County Shoreland Ordinance contain standards for agricultural uses in shoreland. Agricultural uses are permitted in shoreland areas if steep slopes and shore and bluff impact zones are maintained in permanent vegetation.
Ravine, stream bank and bluff erosion contribute significant amounts of sediment to rivers and streams. The MPCA report, Identifying sediment sources in the Minnesota River Basin, found the Blue Earth and Le Sueur watersheds contribute as such as half of the sediment to the Minnesota River, even though they account for only one-fifth of its drainage area. These watersheds contain the majority of the bluffs in the basin as well as many large
The East Branch Blue Earth River is currently negatively impacted and has been shown to contribute disproportionately high sediment loads to the Minnesota River. With limited funds available for implementing conservation practices, targeting tools to pinpoint locations where conservation practices have the highest effectiveness are increasingly important. Innovative use of technology can help streamline these targeting procedures.
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.
