The Faribault Soil and Water Conservation District will provide mini-grants to conservation-conscious community organizations who voluntarily construct best management practices that provide storage and treatment of stormwater runoff at its source.
With limited funds and limited staff time available for targeting critical service areas and implementing Best Management Practices (BMPs), Geographic Information System (GIS)-based tools that pinpoint locations where BMPs will have the highest effectiveness are increasingly important. The Blue Earth County/SWCD Watershed Implementation Targeting project will utilize LiDAR topographic data to determine areas of high importance for BMP implementation. The county is located in the Blue Earth, LeSueur, Watonwan and Middle Minnesota watersheds where there is a high density of impaired waters.
This project will conduct Inventory and Inspection of four drainage ditches in Blue Earth County: JD116, CD5, CD86 and CD56. The inventory of these drainage ditches is important in order to identify where erosion, sediment and/or nutrients contribute substantially to water quality degradation. The project will also prioritize sites for future side inlet control, buffer strip implementation, and/or storage and treatment implementation.
The Faribault County Soil and Water Conservation District Drainage Engineer will inventory public drainage ditches to identify priority systems and areas where erosion, sediment, and nutrients contribute to water quality degradation. Sites identified for potential side inlet control, buffer strip need, or water storage will be prioritized for landowner contact and follow through by seeking external funding opportunities.
Working with a consultant, a current online database to manage public drainage systems will be enhanced and a corresponding mobile inspection app will be developed to facilitate drainage compliance and improve inspection planning. With these improvements, a long-term, comprehensive, GIS-compatible database will be in place to help plan, collect, document, summarize, and analyze system condition, repair needs, and violations with the overall goal of protecting and improving water quality.
The Greater Blue Earth River Basin Alliance is a Joint Powers Organization consisting of nine member Counties and Soil and Water Conservation Districts encompassing the Blue Earth, Le Sueur and Watonwan River Watersheds. This project will enable the Alliance to continue to provide staff and add capacity in the areas of technical assistance, education and outreach.
Faribault County Soil and Water Conservation District will develop two watershed plans using charettes, an intensive planning process used to engage citizens, conservation agencies, and others to collaborate on a vision for the development of a drainage watershed scale plan. The process allows landowners, producers, businesses, townships, cities and the county to partake in a comprehensive plan directly relating back to concerns and solutions related to surface water and nonpoint source pollution.
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.
To be able to manage resources in the Blue Earth and Le Sueur Watersheds into the future and have a positive effect on water quality, resource managers need high quality accurate data to support decision making of best management practice (BMP) implementation. Digital elevation data is a valuable resource for modeling water flow, however in its current state it cannot represent water conveyance through features such as roadways. These flow barriers limit the accurate use of data for recently developed targeting tools identifying BMP suitability and effectiveness down to the field scale.
