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.
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.
The goal of the Pomme de Terre River Association (JPB) is to improve the local water resources within the watershed through targeted voluntary efforts and the building of strong relationships with local landowners, producers, and citizens. The Pomme de Terre River is currently not meeting state water quality for sediment. The purpose of this project is to strategically work towards a 53% sediment reduction goal at the mouth of the Pomme de Terre River based on a Watershed Restoration and Protection Strategy document.
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.
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 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 Accelerated Water Quality Project Implementation Program will increase the connection between landowners, local government units and the landscape to accelerate efforts addressing non-point source loading to surface waters throughout the Red River Valley Conservation Service Area.
South Central Technical Service Area (SCTSA) will use this Clean Water Fund grant to provide Soil and Water Conservation Districts and other local organizations in its eleven-county area with a Geographic Information System (GIS) Technician to assist in using available GIS information to target specific locations where Best Management Practices (BMPs) can be installed to help improve water quality.
Funds are to be used to protect, enhance and restore water quality in lakes, rivers and streams and to protect groundwater and drinking water. Activities include structural and vegetative practices to reduce runoff and retain water on the land, feedlot water quality projects, SSTS abatement grants for low income individuals, and stream bank, stream channel and shoreline protection projects. For the fiscal year 2012, BWSR awarded 13 local governments with funds to complete 143 projects. More information is available in the detail reports below.
This project will improve water quality in the nutrient impaired Fairmont Chain of Lakes. These 5 lakes are a surface water drinking water source for a City of over 10,000 people. Phase one of this multi-phase water quality restoration project focuses on installing 12 targeted agricultural best management practices such as bioreactors, saturated buffers and grassed waterways and will reduce nitrogen by over 1,000 pounds per year, sediment by over 130 tons per year, and phosphorus by over 200 pounds per year.
Currently, there are approximately 5,050 feedlots with fewer than 300 animal units that need to come into compliance with State feedlot rules. Clean Water Feedlot Water Quality Management Grant funds are being used to provide financial assistance to landowners with feedlot operations less than 300 animal units in size and located in a riparian area or impaired watershed.
The Hubbard County Community Partners Conservation Program will give community groups the resources necessary to build interest in, and awareness of, the water quality challenges facing their lakes and empower them to make positive improvements in the form of reduced stormwater runoff. Through the design of a collaborative effort, the Hubbard Soil and Water Conservation District and Local Water Plan Task Force will enable Hubbard County residents and lake home owners to work together to address the effects of development with stormwater runoff solutions.
The north-central Minnesota counties of Cass and Hubbard share large portions of the Crow Wing River, Leech and Upper Mississippi Watersheds, all of which play an important role in providing clean drinking water to over one million Minnesota residents. Each county assumes the responsibility of inspecting and evaluating the judicial and county ditch systems that drain directly into these watersheds. The two counties together share two judicial ditch systems and combined have an additional 42 ditches within their borders.
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.
As lake-focused development continues these high quality waters will see increasing amounts of land use change. The State Demographer projects that the targeted lake catchments will see population increases of 25-62% within 20 years. Isolating these contributing areas permits the Lake Protection Analysis project to perform multiple GIS analyses to accurately inform water quality discussions. The final framework will allow local water managers to prioritize across their water bodies, target activities to specific subsheds, and develop measurable goals.
The Lake Ida and Ditch 23 Wetland Feasibility Project will investigate and review the phosphorus loading of Lake Ida and design a project to protect Lake Ida water quality. Lake Ida is a 'high quality, unimpaired lake at the highest risk of becoming impaired' according to MPCA's Lakes of Phosphorus Sensitivity Significance. With the County Ditch 23 inlet identified as a priority area to reduce phosphorous, a professional engineering firm will explore the best solution to reduce phosphorus.
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.
Minnesota statutes and pre-design costs can prevent conservation practices from being explored earlier during the analysis of public improvements to watersheds. With a large increase in the requests for drainage improvements, the Martin County Drainage Authority feels that planning assistance for conservation practices earlier in the process will give these practices a better opportunity for implementation as part of repair and improvement projects.
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 Greater Blue Earth River Basin Alliance (GBERBA) along with Soil and Water Conservation Districts, Counties, landowners, and drainage authorities in the ten member counties will install conservation drainage practices to improve water quality. 103E drainage systems with documented sediment or water quality issues are the focus with the goal of installing 52 practices such as improved side inlets (grade stabilization structures), alternative tile inlets, denitrifying bioreactors, saturated buffers, storage wetlands and others.
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.
The goal of the Pomme de Terre River Association (JPB) is to improve local water resources within the watershed through targeted voluntary efforts and build strong relationships with local landowners, producers, and citizens. Utilizing the State's first Watershed Restoration and Protection Strategy, the JPB has targeted and identified specific areas and activities required for marked water quality improvement.
The Prioritization, Targeting, and Measuring Water Quality Improvement Application (PTMA) connects the general qualitative strategies in a Total Maximum Daily Load (TMDL) and Watershed Restoration and Protection (WRAP) and the identification of implementable on-the-ground Best Management Practices (BMPs). Leveraging geospatial data from the International Water Institute this application will be developed for two pilot areas within the Red River Basin.
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.
This project seeks to inventory twenty registered feedlots identified as having an Unpermitted Liquid Manure Storage Area. Specifically, this inventory would include offering cost-share for soils investigations. These feedlots are located in three townships that have also been identified as having groundwater that is vulnerable to nutrient pollution, necessitating a need for nitrate testing per MN Department of Agriculture. These townships also house the vast majority of remaining unpermitted Liquid Manure Storage Areas in the County.
