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.
The purpose of this program is to engage community groups for the installation of community accessible rain gardens and other water quality best management practices in Ramsey County. The goal is to install 6-12 storm water best management projects that will help protect and improve water quality of surrounding lakes. The installed practices will reduce an estimated 10 acre-feet of storm water runoff, 9 pounds of phosphorous, and 3 tons of sediment annually. Significant measurable outputs, with development of long-term partnerships, are primary objectives for this program.
The Benton County Water Plan advisory committee has the goal of protecting groundwater resources in Benton County. One of the methods identified is to seal unused wells. In 2013, Benton Soil and Water Conservation District completed an aggressive campaign to identify unused wells. We used several sources to locate potential wells, completed site visits for many wells and collected site information to assisting in prioritizing limited cost share resources.
This grant will fund the creation of a new Coordinator position with a primary focus on the Mille Lacs Lake subwatershed. Although not currently impaired, the Lake faces increasing development and land use pressure. Implementation of protection strategies is essential to the Lake's long-term health but current staffing does not allow sufficient time to be spent on project development and outreach to identify interested landowners.
Little Lake Johanna is not meeting state water quality standards due to excessive phosphorus. The Rice Creek Watershed District, in partnership with the City of Roseville, will improve the water quality of stormwater runoff into Little Lake Johanna through installation of an iron-enhanced sand filter. The Oasis Pond Iron-Enhanced Sand Filter Project will annually remove approximately 34 pounds of phosphorus from runoff to Little Lake Johanna annually. This is equal to nearly 20% of the needed load reduction as established by the Southwest Urban Lakes Total Maximum Daily Load Study.
Golden Lake does not meet state water quality standards due to high phosphorus levels. The proposed iron enhanced sand filter basin was identified in the Golden Lake Subwatershed Stormwater Retrofit Analysis to be one of the most cost effective remaining practices for reducing external phosphorus loads to Golden Lake. This project, paired with two previously installed upstream Best Management Practices, will achieve on average, 84% of the phosphorus reduction goal for the watershed.
Ramsey County, the most densely populated county in Minnesota, generates high levels of contaminated runoff from its impervious surfaces, which can have damaging effects on both surface water and groundwater. Concerns arise when these contaminants drain into abandoned and unused wells, threatening the quality of groundwater, especially in drinking water supply areas, wellhead protection areas, or groundwater recharge zones.
Under the CREP partnership with USDA, 71 easements were recorded on a total of 4,365 acres to restore previously drained wetlands and adjacent uplands. The easements were accomplished with local implementation done by SWCD, NRCS and FSA staff within the 54 county CREP area and leveraged federal funds for both landowner payments and cost share for conservation practice installation.
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 with the assistance of the Board of Water and Soil Resources protects both public health and groundwater by assuring the proper sealing of unused wells.” Clean Water funds are being provided to home owners as a 50% cost-share assistance for sealing unused private drinking water wells.
Investigate unlocated or undocumented wells within the DWSMA; Notify owners of large storage tanks located with the DWSMA; Update the City's septic system inventory.
The Ramsey Conservation District is partnering with the Vadnais Lake Area Water Management Organization, St. Paul Regional Water Service, and Ramsey County Parks and Recreation to restore and stabilize approximately 550 linear feet of streambank along the Sucker Lake Channel in northeastern Ramsey County with a cost effective critical area planting, replacing the existing mix of turf grass and asphalt streambank with a native vegetation planting.
The Mississippi River is currently listed as impaired for turbidity. Eroding riverbanks are one of the causes of this impairment. An inventory was completed in 2016 of riverbank condition along 5.8-miles of the Mississippi River that is within the City of Ramsey. In this inventory, ten severe to very severe eroding stretches spanning 27 private properties and 6,550 linear feet were identified. Cumulatively, these sites contribute 5,148 tons of sediment per year to the river.
