2018 Marshall County Multipurpose Drainage Management Grant
$750,000 the first year and $750,000 the second year are for technical assistance and grants for the conservation drainage program in consultation with the Drainage Work Group, coordinated under Minnesota Statutes, section 103B.101, subdivision 13, that includes projects to improve multipurpose water management under Minnesota Statutes, section 103E.015.
Marshall SWCD will continue to work cooperatively with the Middle-Snake-Tamarac Rivers Watershed District Ditch Authority and the
landowners involved to reduce erosion and sedimentation, reduce peak flows and flooding, improve water
quality and protect drainage system efficiency for priority Chapter 103E drainage systems by installing ten sites for grade stabilizations implementation. The priority Chapter 103E drainage system is State Ditch 3. The ten priority State Ditch 3 locations were targeted from the Middle-Snake-Tamarac Rivers Watershed District staff. These ten sites have either significant erosion issues on the outlets of the existing Side Water Inlets (SWIs) and/or the existing culverts have snapped in two and are no longer effective. The estimated annual reduction in sediment being delivered to Snake River which outlets directly into the Red River of the North is 240 tons per year for the entire project.
Marshall SWCD has already been proactive in selecting locations where multipurpose drainage
management practices are needed to reduce soil loss, eliminate sediment deposition in the impaired ditch
systems, improve water quality, and reduce maintenance costs with the installation of close to 100 NRCS Conservation
Practice Code 410 practices over the past five years.
LOCAL LEVERAGED FUNDS
State Ditch 3 outlets into the Snake River, which outlets directly into the Red River of the North which is on the TMDL Impaired Waters List for Turbidity. Marshall Soil and Water Conservation Ditch is targeting sediment using 10 grade stabilization Structures and side inlets.
