Little Rock Lake experiences severe algae blooms due to excess phosphorus and these blooms are the worst known regionally. The goal of this project is to reduce algae blooms, improve water clarity, and avoid risk of drinking water contamination. The project will result in installing one farmer nutrient management project , four cover crops, two lakeshore buffer strips, six septic systems that also demonstrated an imminent threat to public health, six erosion control projects , one wetland restored, and one feedlot runoff control system.
Little Rock Creek, a cold-water trout stream in central Minnesota, is impaired due to the lack of trout and other cold water fish. The trout are absent because of high water temperatures, low dissolved oxygen and high nitrate levels, stressors caused from a lack of base flow and overuse of groundwater. This project continues a 2011 initiative to assist irrigators in the Little Rock Creek groundwater recharge area with managing the timing and amount of irrigation applied to their crops.
The Little Rock Lake Total Maximum Daily Load study has identified areas in the watershed where phosphorus reduction is needed and what best management practices need to be applied. This is a coordinated implementation effort with Benton and Morrison Soil and Water Conservation Districts and Natural Resources Conservation Service, the Little Rock Lake Association, the livestock industry and other partners to install best management practices at numerous sites to continue cleaning up Little Rock Lake.
The West Central Technical Service Area (WCTSA) serves 12 Soil and Water Conservation Districts (SWCDs) in west central Minnesota and has been experiencing increased workload due to greater requests from member SWCDs. This funding will sustain a limited-term technician and purchase related support equipment to assist landowners in implementing targeted, high priority practices that result in the greatest water quality outcomes.
