In Dakota County, groundwater supplies more than 90 percent of the drinking water. In order to protect Dakota County's primary drinking water source, this project proposes to support the County well seal grant cost-share program. The project will provide 50 percent cost-share funding to reimburse landowners for the sealing of unused wells. The goal is to permanently seal between 80-100 unused/abandoned wells throughout the county.
This project will improve surface and groundwater quality in the rural sections of the Vermillion and North Cannon River Watersheds located in Dakota County through the installation of targeted structural and vegetative conservation practices. This project will leverage local and federal funds to provide technical and financial assistance to landowners that install agricultural water quality practices.
A direct appropriation of $400,000 in FY 2010 for the Anoka Conservation District (ACD) is for the metropolitan landscape restoration program for water quality and improvement projects in the seven-county metro area (the law also provides $600,000 for this purpose in FY2011).

Prevention of groundwater contamination from unused, unsealed wells is identified as a priority in the 2020-2030 Dakota County Groundwater Plan. Dakota County plans to prevent groundwater contamination, especially in drinking water supply management areas, by completing a well inventory in the Black Dog Watershed area to identify suspected abandoned wells, and provide 50% cost-share grants to seal approximately 13 unused, unsealed wells in the watershed.
Seminary Fen, a 600-acre complex in Carver County, supports one of only 500 calcareous fens in the world and is one of the highest quality calcareous fens in southern Minnesota. The Fen feeds Assumption Creek; one of the metro area's last known trout streams that supports naturally reproducing native brook trout. Assumption Creek then discharges to the nearby Minnesota River. The Fen's unique hydrology, soils, plants, and habitats are highly sensitive to water quality and sedimentation stress.
This project will continue and build on the momentum developed through the successful Stormwater Retrofit Partnership (Partnership) from FY2010 and 2012 CWF. This project retrofits stormwater practices on public land to assist partnering Local Government Units (LGUs) in achieving water quality goals identified in local stormwater plans by providing technical assistance and cost share funding.
This project will provide cost share funding to organizations and associations to construct medium-sized water quality conservation projects in Dakota County. This project will continue the successful FY2012 Dakota County Community Partners in Conservation. The Community Initiative program will use the 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, and bioswales.
This project will provide cost share funding to community organizations and associations to construct medium-sized water quality conservation practices in Dakota County.
The karst topography of southeast Minnesota increases the possibility of drinking water supplies becoming contaminated with high concentrations of nitrates. To address this risk in the region, there needs to be an increase in the use of nitrogen best management practices and agronomic rates of nitrogen need to be fine-tuned to balance production with environmental degradation. In addition, potential point sources of nutrient contamination in groundwater need to be addressed wherever possible. This project will have three components that will address these needs.
Long Lake is impaired for nutrients and is a high priority in the City's Surface Water Management Plan and the Vermillion River Watershed Management Plan. As part of a pond feasibility study funded by 2021 WBIF dollars, the City identified pond EVR-P11 as a high quality project to help reduce nutrients in the watershed. The city is requesting $115,331 for a project that will include the excavation of existing pond, reconstruction of the pond outlet, and the installation of infiltration bench. The project will provide approximately 2.21 lbs of Total Phosphorous removal.
The VRWJPO and partners will be completing two activities under this grant. These activities include 1) a stream restoration project at Middle Creek in the City of Lakeville, and 2) an alum treatment feasibility study for Alimagnet Lake in the Cities of Apple Valley and Burnsville. The outcome for the Middle Creek restoration project is an estimated removal of 10.75 tons/year of TSS and 64.5 lbs/year of TP. The outcome for the alum treatment feasibility study is one completed lake alum treatment feasibility study.
The VRWJPO, and its partner, the City of Lakeville, propose the installation of a fish barrier to prevent migration of rough fish between East Lake in Lakeville, MN and the North Creek tributary of the Vermillion River (North Creek). The partners also propose rough fish removals from East Lake. East Lake is a nutrient-impaired water body. Rough fish, specifically common carp and goldfish are both invasive species that have been found to be exacerbating internal nutrient load issues within East Lake.
The project involves installation of a number of stormwater best management practices in the road right-of-way and on adjacent public property during reconstruction of Johnny Cake Ridge Road and installation of the Dakota County North Creek Greenway. Practices implemented will include boulevard raingardens, tree trenches, and underground sediment collection practices.
In 2010, the Minnesota Pollution Control Agency listed Keller Lake as impaired for excess nutrients. An in-lake alum application was identified as the primary phosphorus load reduction option for controlling internal phosphorus load in Keller Lake. A recently completed in-lake management feasibility study report indicates that the in-lake alum application is the most cost-effective implementation project that remains for Keller Lake.
The City of Apple Valley will conduct a subwatershed assessment on the sections of Apple Valley draining to Keller Lake to target potential projects. The goal is to identify potential cost effective retrofit projects and operations improvements capable of fulfilling needed phosphorus reductions ahead of a number of planned infrastructure projects tentatively scheduled for 2018-2022.
The Keller Lake Water Quality Improvement Project achieves the goals of the City of Burnsville, Black Dog Watershed Management Organization, and the Keller Lake TMDL by:-Achieving the City of Burnsville phosphorus removal requirement outlined in the Keller Lake TMDL by removing 78 lbs/yr-Utilizing remaining available land to construct a high performance, regional stormwater BMP-Providing a high profile water resource/stormwater educational opportunity in the frequently visited Crystal Beach Park-Retaining valuable open space in popular Crystal Beach Park by constructing the BMP undergroundK
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.
Dakota County is partnering with the Dakota Soil and Water Conservation District to preserve and enhance the chain of shallow lakes in Lebanon Hills Regional Park which is owned and operated by Dakota County and located within the City of Eagan. Dakota County proposes to construct two regional iron-enhanced sand filtration practices to achieve the load reduction goals set forth in the LHRP Subwatershed Assessment Report to protect Jensen and Schulze lakes and prevent them from being listed on the 303(d) Impaired Waters List. The project will reduce 26 pound of phosphorus annually.
Lake Augusta and Sunfish Lake are deep lakes located in the Lower Mississippi River Watershed Management Organization. Both lakes are approximately 40 acres in size and surrounded by watersheds with moderate to low imperviousness. Both lakes are included on the MPCA's 303(d) list as impaired for aquatic recreation due to excessive nutrients. Lake Augusta and Sunfish Lake were included in a watershed restoration and protection strategies (WRAPS) study and total maximum daily load (TMDL) performed from 2012 to 2014.
