2022 Wright County WASCOBs on Joint Ditch #15
The Wright County Drainage Authority in partnership with the Wright Soil and Water Conservation District (SWCD) is looking to utilize MDM funding to prevent significant erosion and provide peak flow reductions in the area surrounding Joint Ditch #15. Joint Ditch #15 drains into numerous impaired waters such as Sucker Creek, Cokato Lake, and eventually the North Fork Crow River which is our top priority for water quality improvement practices. This proposed project would include the installation of 24 WASCOBS (NRCS code 638) and one grade stabilization structure (NRCS Code 410).
Anticipated Project Cost: $390,000
Total Requested: $210,000

(j) $850,000 the first year and $850,000 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, and including projects to improve multipurpose water management under Minnesota Statutes, section 103E.015.
The HydroCAD modeling of this project shows a projected reduction of 157lbs of phosphorus and 98.87 tons of sediment per year. The outflow hydrograph also shows a significant reduction in peak flows of 91% from the field during a 10-year rain event.
Wright County exceeded their estimated measurable outcomes for all project pollutants. In some cases this was by an order of magnitude such as the soil savings (1120 tons/acre) which was almost 10X the estimated reduction on the grant application. The phos (320 lbs/acre) and sediment (206 lbs/acre were both double the predicted amounts.
