CD 10 BMP Inventory - Implementation #2
CD 10 is a 16 mile long ditch system located in Wright County and lies within the North Fork Crow River Watershed. CD 10 is one of Wright County's largest public drainage systems with an approximate 16,707 acre watershed. There has been a lack of maintenance on CD 10 since its establishment in 1906. A system wide repair is planned for 2021 (draft repair report is complete and awaiting adoption as of the date of this grant application). The CD 10 drainage system constitutes the headwaters for several impaired waterbodies (Ann, Emma, and Little Waverly Lakes, 12 Mile Creek, and the North Fork Crow River). The goal of this project is to implement 34 alternative side inlet control structures (ASIC's - CPS Code 410) in conjunction with the system wide repair that will reduce downstream sediment and phosphorus loads. Sediment and phosphorus reductions are estimated to be 42.82 tons/year and 73.1 lbs/year respectively. Other eligible practices will be considered depending on site specific information obtained during project development.

(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, that includes projects to improve multipurpose water management under Minnesota Statutes, section 103E.015.
Each ASIC is estimated to reduce 1.26 tons sediment/year and 2.15 lbs TP/year to Lake Ann. Implementation of 34 ASIC's would reduce sediment loads by 42.82 tons/year and TP loads by 73.1 lbs/year to Lake Ann.
As a result of this grant, the project has achieved the following outcomes: 93.7 tons/year soil saved, 77.47 tons/year TSS removed from the system, and 130.52 lbs/year phos reduced. This exceeded the proposed outcomes so the applicant has exceeded their proposed objectives.
