This project targets nutrient reductions within the Mayhew and Big Elk Lake watersheds. The Benton Soil and Water Conservation District will work with farmers in implementing a variety of conservation practices including, but not limited to cropland erosion control projects, riparian pasture management, and nutrient management and feedlot pollution control systems. These strategies were identified through Total Daily Maximum Load Studies.
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.
A completed Total Maximum Daily Load (TMDL) study has identified mid to late summer phosphorus loading as a significant stressor to lakes and streams within the Big Elk Lake watershed. While this comprehensive study serves its role as the unifying document that identifies pollutants and sources, further work is required in order to develop site-specific Best Management Practices, design these practices, and oversee their implementation in order to reach clean water goals.
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.
The funds requested will provide Big Lake Township with the technical and financial assistance necessary to retrofit up to six locations for stormwater treatment practices within the direct drainage area of Birch Lake, an impaired water body which is very close to meeting state standards. The projects have been identified as high priority in several water quality plans including a TMDL, a subwatershed assessment, the County Water Plan and the Mississippi River (St. Cloud) WRAPS.
The Briggs Lake Chain Association (BLCA) is one of Sherburne County's most proactive lake associations. This sub-grant will provide for approximately 20-30 stormwater reduction best management practices on strategically targeted parcels previously identified as contributing to degraded water quality through Total Maximum Daily Loads, aerial lakeshore analysis and site-reviews conducted by the BLCA.
This project targets an older residential area that does not have permanent water quality practices. Storm water presently runs directly to the Mississippi River using out of date and under-sized infrastructure. Expanding upon a very successful pilot program for retro-fitting storm water treatment practices in residential neighborhoods, rain gardens will be strategically placed to maximize water quality benefits for each dollar spent. Each rain garden will have a pre-treatment device to help achieve the cost-effective long-term water quality goals of the City.
The Elk River Watershed Association Joint Powers Board, via the Sherburne Soil and Water Conservation District, will utilize project funds to implement a pasture and manure management program which will provide technical and financial assistance to large animal/hobby farm owners. Staff will work with identified landowners to implement bacteria reduction best practices such as pasture renovation/management, riparian buffer strips, clean water diversions, vegetated buffer strips, and manure management including composting structures.
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.
It is critical to train new staff, create modeling protocols for new BMPs, refine and calibrate models, and test ever-advancing modeling applications. The Metro Conservation District?s (MCD) Sub-Watershed Analysis (SWA) program provides these capacity-building services and unites efforts across 11 SWCDs. MCD proposes to analyze an additional 15 subwatersheds. The analyses will identify the location and estimated cost/benefit relationship for BMPs, evolve with new technology, and share discoveries metro-wide.
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.
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.
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.

The goal of the project is the reduction of nitrates in the groundwater by promoting and implementing best management practices and alternative management tools in the priority areas of Sherburne County. Practices included in the application are: Cover crops, irrigation water management , and nutrient management. Additional incentives included are for the Conservation Reserve Program. District Staff will also plant at least one acre of demonstration plots which will be highlighted at an annual field day.
