This project targets retrofit stormwater Best Management Practices (BMPs) on public land to assist partnering Local Government Units (LGUs) achieve water quality goals identified in local stormwater plans. The Dakota County Soil and Water Conservation District (SWCD) provides technical assistance and distributes Clean Water Funding (CWF) to leverage local funding through its time-proven Stormwater Retrofit Partnership (Partnership) cost share program.
This project is a continuation of the Dakota County Community Initiative, which has received Clean Water Funds in 2012 and 2013. It will provide cost share funding to organizations and associations who voluntarily construct medium sized water quality best management practices (BMPs) in Dakota County.
This project will use the Dakota County Soil and Water Conservation District's existing Conservation Initiative Funding program to provide technical assistance and monetary incentives for targeted, medium-sized projects such as raingardens, bioinfiltration, biofiltration, bioswales, shoreline stabilizations, and other best management practices (BMPs). Project proposals will be solicited from faith based organizations, homeowner associations, school organizations, lake associations, and others that own or manage large areas of land.
The Vermillion River Watershed Joint Powers Organization, in partnership with the City of Burnsville, is planning an overall improvement in the Alimagnet Lake subwatershed that consists retrofit two existing stormwater ponds that drain to Alimagnet Lake, a nutrient impaired water, with iron-enhanced sand filter benches. It is estimated that a significant amount of phosphorus reduction will be achieved by implementing this project, bringing Alimagnet Lake closer to state water quality standards.
As part of the Dakota County Transportation Department's highway 78 road reconstruction project, the Vermillion River Watershed Joint Powers Organization is partnering with Dakota County to install a nitrate treatment practice on a tributary to the South Branch Vermillion River adjacent to the road. The South Branch Vermillion River subwatershed is the highest nitrate loading subwatershed in the Vermillion River Watershed and is a significant contributor to contaminated drinking water in the eastern portion of the watershed.
South Creek is a tributary to the Vermillion River and a DNR-designated trout stream. Currently, the creek is not meeting state water quality standards for sediment, temperature and dissolved oxygen The Vermillion River Watershed Joint Powers Organization and the City of Lakeville propose to retrofit an existing stormwater pipe with a hydrodynamic separator to reduce the sediment load reaching South Creek and the Vermillion River. One hydrodynamic separator will be installed and is estimated to reduce sediment loads to South Creek and the Vermillion River by 4 tons per year.
The Vermillion River Watershed JPO is partnering with Dakota County and the City of Lakeville to enhance stormwater management along County Road 50. A treatment train approach with an iron-enhanced sand filter at the tail end to remove dissolved phosphorus will be implemented to treat a drainage area including a portion of the upstream neighborhoods that currently receive little to no stormwater treatment. The practice is anticipated to reduce 20 pounds of phosphorus annually from reaching Lake Marion, a water resource with high recreational value targeted for protection.
South Creek, a tributary to the Vermillion River and a DNR-designated trout stream. Currently, the creek is not meeting state water quality standards for sediment, temperature and dissolved oxygen and it flows through a large stormwater basin in the City of Lakeville. The Vermillion River Watershed Joint Powers Organization, in partnership with the city, propose to create a new channel for the creek in order to separate it from the pond. The result would be significantly cooler temperatures, increased dissolved oxygen, and less sediment-laden water in South Creek.
This project will identify and prioritize opportunities to implement a multipurpose drainage management plan that will provide adequate drainage capacity, reduce peak flows and flooding and reduce erosion and sediment loading, improving water quality to the West Branch Rum River.
King Park, a city-owned park in Lakeville, consists of baseball fields, a park building, and a parking lot. A portion of Dodd Blvd, a driveway, and the parking lot drain to a stormwater pond at the north end of the park where water is retained, treated, and reused to irrigate two ball fields. This stormwater reuse project was constructed by the Vermillion River Watershed Joint Powers Organization (VRWJPO) and the City of Lakeville in 2010 to meet VRWJPO and city goals.
Lake George is the premier recreational lake in Anoka County with above average water quality, a vibrant fishery, and a large regional park and beach that is among the most utilized in the county. Located in northwestern Anoka County within the Upper Rum River Watershed Management Organization (URRWMO), the Lake George Improvement District (LGID) was formed to tend to the lake's diminishing water quality and problematic invasive species.
The Cannon River Watershed includes approximately 941,000 acres of primarily agricultural landscape. Because of its large size, four subwatershed lobes are often referenced: Straight River Watershed, Upper Cannon River Watershed, Middle Cannon River Watershed, and the Lower Cannon River Watershed. Rice County is proposing utilizing LiDAR topographic data to determine areas of highest importance for Best Management Practice (BMP) Implementation for sediment within the Middle and Lower Cannon subwatersheds.
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.
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 purpose of this project is to complete subwatershed analysis for Cannon River and Vermillion River sub-watersheds to prioritize and target Best Management Practices based on cost-effectiveness with regard to pollutant reduction. This process is intended to proactively assist local water management and partner agencies in maximizing the value of each dollar spent to improve water quality in the respective rivers.
