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.
These funds are being used to systematically collect data and produce statistically valid estimates of the rate of soil erosion and tracking the adoption of high residue cropping systems in in the 67 counties with greater than 30% land in agricultural row crop production. Designed to establish a long term program in Minnesota to collect data and produce county, watershed, and state wide estimates of soil erosion caused by water and wind along with tracking adoption of conservation measures to address erosion.
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 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.
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.
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.
Through a long standing partnership, this project will continue to implement a process formalized with a 2010 Clean Water Fund Grant to conduct stormwater sub-watershed assessments. The goal of the sub-watershed assessments is to accelerate water quality improvements by focusing efforts in high priority areas. Specifically, subwatershed assessments are a tool used to identify the most effective urban stormwater conservation practice by location.
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 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.
Through this project, the North Cannon River Watershed Management Organization (NCRWMO) works cooperatively with the Dakota Soil and Water Conservation District (DSWCD) and landowners to establish best management practices (BMPs) that reduce runoff and decrease the movement of sediment, nutrients, and pollutants into the Cannon River and its tributaries including, Trout Brook, Chub Creek, and Pine Creek.
In 2002, Farquar and Long Lakes were placed on the impaired waters list due to high phosphorus levels that caused algal blooms and reduced water clarity. The City of Apple Valley is proposing a combination of two enhancements to achieve a 61 pound reduction in phosphorus.
Water from an area in and near the interchange of US Highway 52 and MN Highway 55 spills onto a steep bluff face at the head of a ravine. This has accelerated the amount of sediment eroding from the ravine into the Mississippi River. In partnership with Dakota County, Dakota Soil and Water Conservation District, the City of Rosemount, Minnesota Department of Transportation, Flint Hills Resources, the Vermillion River Watershed Joint Powers Organization has been working for several years to identify a solution to this severe erosion problem.
Schwanz Lake is an 11.5-acre shallow lake in southeast Eagan that was found to be impaired in 2006 due to excessive levels of phosphorus. The land area draining to the lake is 762 acres, but a small a 28-acre residential neighborhood was found to disproportionately contribute 24 percent (roughly 14 lbs/yr) of the phosphorus, according to a 2010 study of phosphorus sources. The neighborhood was developed before Eagan established water quality requirements for stormwater retention ponds and the neighborhood drains runoff directly to the lake through a single pipe.
Over the past two years, Dakota County has learned that many properties within the city do not have septic system records identifying the presence or condition of their septic system, and anecdotal evidence that some are failing. The County will use CWF Accelerated Implementation Grant dollars to inventory and inspect all septic systems within the City of Randolph. As part of the inspection, a well inventory will also be conducted. Based on a preliminary assessment, there are 105 properties that will require inspection.
The lack of sewage treatment in many small communities in Southeast Minnesota is causing surface water and groundwater pollution. Ten of these small communities will be the target of the technical assistance provided by this project. These communities have community or individual straight pipes which are discharging raw sewage directly into the environment, surfacing sewage, or have sewage contaminating groundwater.

Fourteen of these small communities will receive technical assistance provided by this project. These communities have community or individual straight pipes which are discharging raw sewage directly to the environment, surfacing sewage, or have sewage contaminating groundwater.
Through the Stormwater Retrofit Partnership, the Dakota Soil and Water Conservation District (DSWCD) provides the funding and technical assistance to prioritize and install Best Management Practices (BMPs) at existing public facilities. This project is needed because, like other urban properties that developed before stormwater regulations, most government owned facilities were designed and constructed without optimal water quality features.
This project will continues the successful 2010 Stormwater Retrofit Partnership. This resulted in the retrofit of 18 sites including eleven bioretention cells and seven snowmelt management areas. These retrofits provided treatment for 28 acres of urban drainage area - reducing total suspended solids, total phosphorus and stormwater volumes.
Thompson Lake is a shallow lake located in the City of West St. Paul, within the Lower Mississippi River Watershed Management Organization (LMRWMO). The 7-acre lake receives runoff from a 175-acre urban watershed that was developed in the 1950's and currently provides very little stormwater treatment. The eastern shoreline is within Thompson County Park, which features a fishing pier, event center, and miles of regionally connected trails. The west shoreline of the lake abuts the St. Croix Lutheran School.
