Judicial Ditch 15 BMPs
In October 2018, a petition for improvement of Lyon-Redwood Joint Judicial Ditch No. 15 (JD15) was accepted by the Lyon-Redwood Joint Drainage Authority. To control gully erosion and improve water quality, four water and sediment control basins are being proposed in the JD15 Final Engineer's Report. The basins will temporarily store overland runoff from within the watershed, allowing sediment and nutrients to settle out during dewatering. Clear Creek headwaters reach 07020006-567 is listed on MPCA's 2022 impaired waters list for impairments due to total suspended solids. The proposed BMP's aim to reduce TSS by 64.0 tons/year, soil by 294.8 tons/year, and phosphorus by 73.6 lbs/year. Flow reduction of 0.7CFS (-1%) during 2-year events, 130.9 CFS (-53%) for the 10-year events and 28.7 CFS (-8%) for the 100-year event at the improved subsurface drain outlet of JD15 into the main open ditch. Discharge depth decreases of 2.7 feet during the 10-year storm event were also modeled.

(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.
Estimated reductions of 64.0 T/year TSS, 294.8 T/year soil, and 73.6 lbs/yr phosphorus. Flow reduction of 130.9 CFS for the 10-year event and 28.7 CFS for the 100-year event at the improved subsurface drain outlet of JD15 into the main open ditch.
