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.
These funds will be utilized in cost-share for landowners to install Agricultural Best Management Practices following Little Rock Lake TMDL Implementation Plan. Example of projects include Feedlot Improvements, Waste Storage Facilities, Erosion Control BMPs, Filter Strips and Streambank Stabilizations. An estimated 830 pounds per year of phosphorus and 800 tons of sediment will be reduced annually.
This site has been monitored for several years due to past storm events causing flood waters that impacted State Highway 371 and Belle Prairie housing developments. This site is contributing large amounts of sediment and is one of the worst erosion sites identified along the Mississippi River in Morrison County.
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 Morrison County Board has stepped up their efforts to examine septic compliance for any septic not inspected within five years. They assigned the Local Water Plan task force to develop a pilot plan to show how it would work and whether further enforcement action is appropriate.
Approximately 70 percent of all Minnesotans rely on groundwater as their primary source of drinking water. Wells used for drinking water must be properly sealed when removed from service to protect both public health and Minnesota’s invaluable groundwater resources. The Minnesota Department of Health protects both public health and groundwater by assuring the proper sealing of unused wells.
Clean Water funds are being provided to well owners as a 50% cost-share assistance for sealing unused public water-supply wells.
Grants to counties to implement SSTS programs including inventories, enforcement, development of databases, and systems to insure SSTS maintenance and of reporting program results to BWSR and MPCA and base grants.
A new GIS technician will help prioritize and target conservation activities and protection strategies in nine north-central Minnesota counties. The GIS technician will create GIS products, assessments, and watershed analysis to identify the high priority areas in each County or watershed in need of protection or restoration using all available data, including LiDAR, soils, land use, completed WRAPS and other datasets. These areas will then be targeted for future resource management efforts, Clean Water Fund projects, and additional conservation activities.
