This project combines the use of automated soil moisture probes for irrigation scheduling with diverse cover crop planting to reduce or eliminate leaching of nitrogen and other nutrients on cropland with an early season harvested crop in the rotation. The more efficient use of irrigation waters provides a secondary benefit: less withdrawal from the aquifers that provide recharge for the Mt. Simon-Hinckley aquifer.
This project will focus on Watershed Restoration and Protetion Strategy (WRAPS) and Total Maximum Daily Load (TMDL) report development for the Rum River Watershed, which includes Mille Lacs Lake (the second largest lake in Minnesota) and the Rum River of which Mille Lacs Lake is the headwaters. The project will produce a plan that partners and citizens will be able to implement, a framework for citizen engagement, and a set of watershed management activities that will achieve water quality standards for all impairments within the watershed.
At almost 4,000 acres, Trout Brook is the largest subwatershed in the Capitol Region Watershed District and the City of Saint Paul. The restored stream is part of the 42 acre Trout Brook Nature Sanctuary project, whose goal is to return the area back to some resemblance of its pre-industrialized valley of stream floodplain and wetlands. Monitoring results within the corridor show that phosphorus, sediments, bacteria, lead and copper are the pollutants of most concern.
