School Lake Agricultural Practices

Project Description & Outcomes

This project will implement cover crops and livestock waste management practices on a farm/feedlot in southern Chisago County. Practices include: cover crops, roof runoff management, clean water diversion, waste management system, and vegetated treatment area. The proposed project is estimated to reduce approximately 61 lb/yr of watershed phosphorus loading to School Lake, which discharges through a stream to Little Comfort Lake. The Comfort Lake-Forest Lake Watershed District (CLFLWD) performed diagnostic monitoring to target this phosphorus loading hotspot which includes a cattle feedlot at the headwaters of this tributary. This project is estimated to achieve 29% of the 211 lb/yr watershed phosphorus load reduction goal for School Lake.
