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.
Lower Prior Lake was the target of a 2011-2013 diagnostic and feasibility study that identified projects and ranked subwatershed by phosphorus loading to the lake. This project is in a high loading subwatershed and includes three elements designed to reduce phosphorus loading and control rates and volumes of stormwater runoff: 1) retrofitting an existing ditch section with in-line iron-sand filters; 2) expanding storage capacity and creating wetland upstream of the ditch; and 3) installing a new control structure in an existing berm.
Arctic Lake, while not listed as an impaired water on the statewide 303(d) list, both regularly exceeds the statewide phosphorus standard for shallow lakes and drains directly to Upper Prior Lake, which is impaired for nutrients Reducing Phosphorus to Arctic Lake will help reverse the current declining water quality while also reducing the loading entering Upper Prior Lake.
The Pope County Water Plan has identified surface water quality and erosion control as top priority resource concerns. These two priorities account for 33% of the phosphorus loading to Lake Emily. The Lake Emily Watershed Best Management Practices (BMP) Prioritization Project will provide GIS-based water quality analysis to assist the Pope Soil and Water Conservation District in determining effective locations for BMP implementation and will prioritize the areas from high to low for phosphorus, nitrogen, and sediment delivery from contributing runoff during rainfall events.
Pope Soil and Water Conservation District, partnered with Natural Resources Conservation Service staff and landowners, will install 22 targeted water and sediment control structures in two priority subwatersheds (Trappers Run and Minnewaska). These structures have the potential to reduce sediment load by 514 tons per year, and phosphorus by 440 pounds per year.
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 Pomme de Terre River Association has targeted and identified specific areas and activities required for marked water quality improvement. This project will implement of 16 Water and Sediment Control Basins (WASCOBs), 28 Rain Gardens, 2 Shoreline/ Stream bank stabilization, 10 Waste Pit Closures, 1 Terrace Project, and the enrollment of 1900 acres into conservation practices. These practices in total will directly result in site-specific and watershed-dependent reductions of 17,801 tons of sediment and 17,784 pounds of phosphorous from entering surface waters yearly in the watershed.
The City of Glenwood Water Quality Assessment & Best Management Practice Prioritization Project will include an assessment and analysis of approximately 1,796 acres affecting water quality and contributing runoff to Lake Minnewaska. By implementing this water quality analysis and assessment of the City of Glenwood and sub watersheds, a reducing pollutants by 1,287 pounds per year of phosphorus and 203 tons per year of sediment.
The Lake Emily Watershed BMP Targeted Implementation Project will provide funding for 48 water and sediment control projects and potential shoreline and riparian restoration. This work would address surface water quality sources identified in the water plan (Section 2-pg 11) including direct drainage from the Lake Emily sub-watersheds (070200050304, 070200050303, 070200050203, 070200050201, 070200050202) the Little Chippewa, and from upstream discharge between Lake Emily and Lake Minnewaska.
Pope SWCD has 9 motivated landowners with 21 WASCOBs, 1 lined waterway, and 1 shoreline restoration in two priority sub watersheds (Trappers Run and Minnewaska). Based on averages calculated from recently constructed WASCOBs in the West Central Area II these projects have the potential to reduce TSS by 518 T/year, and 446 lbs./year of TP. This project will provide a secondary benefit to improve downstream water quality to Lake Emily. The project will result in meeting 99% of the Lake Emily TP lbs/yr.
This project proposes significant improvements to the City of Bloomington's Anti-Icing/Brine making capabilities. The use of anti-icing technology reduces the amount of salt needed to clear snow and ice from city street. The improvements work to address the chloride impairment in Nine Mile Creek and the metro area by reducing the amount of salt applied to the streets and thereby reducing the amount of chlorides entering our surface water systems.
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.
Lake Emily is a high priority recreational lake in Pope County and is currently not meeting state water quality standards due to high phosphorus levels. This project will provide funding for 26 water and sediment control projects with potential shoreline and riparian restoration projects. This work will address surface water quality sources including both direct drainage and upstream discharge. Collectively, these projects have the potential to annually reduce sediment and phosphorus leaving the field which will directly address 15% of Lake Emily's phosphorus reduction goal.
This project builds on the momentum and success of previous Clean Water Fund grants in making significant non-point source pollution reductions that address state-identified turbidity, excess nutrient and dissolved oxygen impairments of the Lower Minnesota River and points downstream. These water quality improvements will be achieved by constructing high-value, cost-effective conservation best management practices in Scott County directly tributary to the Minnesota River.
The Lower Shakopee Creek has proportionally higher pollutant contributions than any other tributary in the Chippewa River Watershed, and lower than average implementation of conservation practices. Establishing relationships with agricultural landowners is critical for overcoming barriers to participation. In order to make measurable pollutant reductions, Chippewa River Watershed Project staff will increase one-to-one landowner contacts, program promotion, and Best Management Practice site identification.
Recent efforts by Carver County Water Management Organization Staff have centered on removing point sources of bacteria in both Bevens and Carver Creeks. These efforts have shown improvement in water quality; however the creeks are still above the state standard for E. coli. Early results from field surveys have pinpointed areas where livestock have uncontrolled access to streams. Five sites over a twenty mile stretch of Bevens Creek have shown evidence of livestock access to streams and associated damage to streambanks.
This project will provide administrative support to the Clean Water Partnership (CWP) loan program. By initiating the CWP loan program in Sibley County it will provide low interest loans to bring 21 non-complaint or failing existing systems into compliance by replacing them with new single sewage treatment systems.
In 2002 and 2004, the Minnesota Pollution Control Agency listed Bluff Creek for turbidity and biological integrity. A Total Maximum Daily Load report and implementation plan were finalized and approved in 2013. This project was identified as a high priority site for culvert restoration and bank repairs.
The Burandt Lake Stormwater Reuse System (BLSRS) project will install a water reuse system to capture untreated storm water and reduce pollutants entering Burandt Lake. This collaborative project with Carver County, Carver County Soil and Water Conservation District (SWCD), City of Waconia and Independent School District 110 will retain and reuse an estimated 48% of the annual storm water runoff (1.25 million gallons) currently generated from eight acres of adjacent residential neighborhoods.
Once thought to have an essentially inexhaustible groundwater supply, Minnesotans are now realizing our rates of use are regionally unsustainable. Recent advanced modeling by the MN DNR and Metropolitan Council of aquifer supplies, in conjunction with predicted demand, indicate the major metropolitan area aquifers are currently subject to extraction rates that exceed recharge. Simply stated, we are mining our groundwater.
This project will increase the ability of the Carver County Water Management Organization (CCWMO) to approach local community partners and fund projects that treat stormwater runoff at the source instead of treating stormwater downstream at a regional pond or through other large scale best management practices (BMPs).
The Carver County Planning and Water Management Department (PWM) has an active well sealing cost share program. Following the adoption of the updated County Groundwater Plan in February of 2016, the Carver County Board of Commissioners moved to accelerate the program to encourage landowners to seal abandoned wells. Carver County is looking to supplement existing funds, as demand is expected to increase. With this additional funding, it is the goal of Carver County PWM to seal an additional 15 wells county wide.
The City of Minnetonka and its residents highly value the water resources within the community, which include approximately ten lakes, four streams, and hundreds of wetlands. The City has been progressive in protecting these resources through policies and management strategies, and now wants to increase their on-the-ground efforts in protecting and improving water quality. The City hopes to conduct targeted watershed assessments for fourteen selected priority water bodies to identify and optimize the type and locations of Best Management Practices (BMPs) to be installed.
The purpose of this project is to install prioritized and targeted best management practices on the Carver County Ditch #6 drainage system that drains directly into Bevens Creek. Bevens Creek does not meet state water quality standards for sediment. The goal of the project is to install 6 grade stabilization structures, 5 grassed waterways, and 2 water and sediment control basins that have been identified through GIS LIDAR applications and field verified along with landowner support.
Carver County has identified water quality improvement of Carver, Bevens and Silver Creek as a water management priority. This project will identify storage or wetland restoration sites that are highly effective at reducing pollutant loading to downstream impaired waters using high-resolution Light Detection and Ranging (LiDAR) data and Geographic Information System (GIS) processes. The watershed landscape has been highly modified for agricultural production land development; less than 50 percent of pre-settlement wetland acres remain in Carver County.
The downtown Chanhassen stormwater best management practice (BMP) retrofit assessment project will reduce watershed phosphorus loads to Rice Marsh Lake and improve the water quality in downstream Lake Riley, impaired for excess nutrients. This project will identify innovative BMP retrofit opportunities that target soluble phosphorus and promote infiltration and groundwater recharge within this highly-developed area. The downtown Chanhassen BMP retrofit assessment project will be performed in partnership with the City of Chanhassen.
The Drinking Water Contaminants of Emerging Concern (CEC) program identifies environmental contaminants for which current health-based standards currently do not exist or need to be updated, investigate the potential for human exposure to these chemicals, and develop guidance values for drinking water. Contaminants evaluated by CEC staff include contaminants that have been released or detected in Minnesota waters (surface water and groundwater) or that have the potential to migrate to or be detected in Minnesota waters.
The purpose of this project is to identify effective irrigation and nutrient management best management practices and technologies and the barriers that prevent irrigators, producers, and other agricultural partners from adopting them in Otter Tail County. The primary goal is to reduce nitrate in areas where groundwater is susceptible to contamination as mapped by The Minnesota Department of Health by identifying effective BMPs and addressing the barriers to their adoption.
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
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.
This is a joint grant application from the Riley-Purgatory-Bluff Creek Watershed District (RPBCWD) and the City of Chanhassen. In 2010, the Minnesota Pollution Control Agency listed Lake Susan as a shallow lake impaired for excess nutrients. A 2013 report recommended a project located at the park pond immediately northwest of Lake Susan as the most cost-effective watershed implementation project. The project calls for an outlet control structure at a higher elevation that will provide increased dead pool storage and the installation of a Minnesota Filter to treat dissolved phosphorus.
A Level III Feedlot Inventory in the West Fork Des Moines River Watershed identified the need for a new manure storage basin. The Heron Lake Watershed District will be partnering with Murray County, Murray Soil and Water Conservation District, and Southwest Prairie Technical Service Area to construct the basin to ensure that manure and milk house wastewater will be properly stored. In addition, the project will decrease the size and usage of open lots using buffer strip and pasture to significantly reduce nutrient loading.
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.
This project will reduce sediment and nutrient loading to the main stem and local tributaries of the Lower Minnesota River (LMR) by providing cost share for practices that treat ravine headcut and channel erosion, streambank/shoreline erosion, ephemeral gully erosion, and direct-discharging open inlet drainage systems. Targeted Best Management Practices (BMPs) will include but not be limited to grade control structures, grassed/lined waterways, water & sediment control basins, shoreline/streambank stabilization and alternative tile inlets.
This project builds on the momentum of previous Clean Water Fund grants in making significant and quantifiable sediment, nutrient and runoff volume reductions to address the turbidity, dissolved oxygen and other impairments of the Lower Minnesota River (LMR). These water quality improvements will be achieved by constructing on-the-ground conservation best management practices (BMPs) in the targeted watersheds -including specifically Sand and Roberts Creek - and near channel sources.
McLeod County will create an inspection database for 103E ditches under their drainage authority. The County will acquire a database software solution to conduct field inspections and to track ditch maintenance projects. This software will be used to facilitate statutory compliance including developing a process for completing the annual inspection and reporting requirements. The project will lead to improving the County's data management capabilities and better identification of drainage system needs that could lead to helping improve water courses that are impaired for turbidity.
Ensuring natural resource practitioners are applying state-of-the-art approaches is the best way to achieve optimum Best Management Practice (BMP) selection, design, and placement in the landscape, thereby maximizing Clean Water Fund (CWF) benefits. To that end, it is critical to train new staff, create modeling protocols for new BMPs, refine and calibrate models, and test ever-advancing modeling applications.
