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.
The City of Inver Grove Heights will remove PAH contaminated sediment from the 79th Street Pond. Approximately 2,300 cubic yards of sediment will be dredged and disposed of at the Pine Bend Landfill located in the City of Inver Grove Heights.
This project will consist of identifying the candidate causes of biological stress and to develop and implement a public and stakeholder participation process that encourages local ownership of water quality problems and solutions. The Stressor ID process will be done using existing data, identifying data gaps, gathering new data, developing load duration curves, and refinement of the candidate causes. The civic engagement work will include compiling and reviewing existing data on community capacity and assessing that information.
This project will build network and the skill set of local resource professionals to do effective civic engagement work for water restoration and protection in Southeast Minnesota. The cohort will be administered through the Southeast Minnesota Water Resources Board (SE MN WRB) which is an area wide Joint Powers Board (JPB) established to help improve and protect the water resources of the area through coordinating local water planning efforts. This JPB has successfully administered water quality grants in the past that have positively impacted the water resources of this region.
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.
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.
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 VRWJPO is pursuing a Watershed Restoration and Protection Strategy (WRAPS) project in cooperation with the MPCA in order to better identify the sources of stress and impairment to the river, tributaries, and lakes and evaluate the feasibility of reaching water quality goals, and properly allocating pollution reduction goals to those areas identified as likely pollution sources. Successful restoration and protection outcomes are dependent on successful community building and ownership of both the problems and solutions identified in the WRAPS.
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.
