This project will consist of retrofitting a dry storm water basin, constructing a new pre-treatment cell, creating new wetland, and reconfiguring the existing inlets and the outlet for better water quality treatment. This project is specifically identified in the Twin-Ryan Lakes TMDL.
The Nine Mile Creek watershed is a highly developed, urbanized watershed located in southern Hennepin County. The natural infiltration capacity of soils in the watershed has been diminished by significant coverage with hard surfaces such as streets, parking lots, and buildings. This leads to more rainfall making its way more quickly to Nine Mile Creek. As a result, Nine Mile Creek has experienced stream bank erosion and instream habitat loss due to increases in storm water runoff resulting in the creek to be listed on the State of Minnesota impaired waters list for biotic integrity.
DNR regional clean water specialists and area hydrologists work with local partners to provide technical assistance on implementation projects and related outreach, resulting in cleaner water through healthier watersheds, shorelands and floodplains. We help partners identify, develop, target, design and/or implement on-the-ground projects that improve water quality, enhance habitat and protect infrastructure. We help design restorations that provide lasting benefits by mimicking features of healthy ecosystems.
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.
The Rum River is designated as a 'Wild and Scenic River' and is the major watershed in Mille Lacs County. Maintaining and protecting its water quality is a significant concern. The Clean Water Fund grant will result in the timely and successful implementation of ten nutrient management plans resulting in land management changes with an estimated average reduction of 30 pounds of Phosphorus and 40 pounds of Nitrogen per year on almost 2,000 acres.
The purpose of the Minnesota Department of Agriculture's monitoring activities is to determine the presence and concentration of pesticides in Minnesota's groundwater and surface water. Monitoring information is used to characterize and assess the extent of pesticide impacts to Minnesota's water resources.
Mille Lacs Lake is recognized as one of the premier walleye producing lakes in the world. The current water quality of the lake is good, however recent monitoring of the lake and its watershed indicates the potential to develop problems. Since 1997, the Mille Lacs Lake Watershed Management Group has worked to preserve the water quality of Mille Lacs Lake. Five priority projects were identified by the Group partners in an effort to preserve water quality. Support for these projects was provided by a grant from the Clean Water Fund.
The SWCD initiated Project Recharge to create and apply a protection strategy to address declining water quality trend reported in a 2008 large lakes analysis. The report contained watershed and trend analysis for lakes over 1,000 acres in size and led to targeting of lands located within lakesheds containing the highest ratio of impervious to pervious surfaces. These included the Cities of Breezy Point, Crosslake, and Fifty Lakes.
This project will develop an effective transferable model to engage and educate watershed residents, stakeholders and others to better understand and protect watershed ecostystems through environmental monitoring, training, and formal and informal education programs in their local watershed. The project will build on the foundation of the existing Red River Basin River Watch program by strengthening three main activity areas: 1) curriculum integration and teacher training, 2) youth leadership and civic engagement, and 3) applied research collaboration and watershed science skills building.
This project will monitor nine locations in the major watersheds (8-digit Hydrologic Unit Codes) of the Lower Red River Basin. The stream outlet monitoring will provide the water chemistry data needed to calculate annual pollutant loads. Staff from the Red River Watershed Management Board (RRWMB) will conduct the sampling, initially manage the data and provide the data to the Minnesota Pollution Control Agency (MPCA) for load calculations and import into the STORET data system.
Stormwater runoff from the City of Kimball drains untreated into Willow Creek, a trout stream. Willow Creek is tributary to Lake Betsy, which is impaired by excess nutrients. This project targets phosphorus removal for Lake Betsy as identified in the Upper Watershed TMDL Studies for the Clearwater River Watershed and protection to Willow Creek trout habitat by infiltrating the 1.5-inch storm event off 428 acres in and around the City of Kimball.
The USGS and the MPCA will determine the relative contributions of endocrine active chemicals (EACs) and pharmaceuticals from WWTP effluent to aquatic ecosystems. The primary objective is to measure the concentrations of EACs and pharmaceuticals in water samples collected from the effluents from 20 WWTPs and at sites upstream and downstream of WWTP effluent discharge in Minnesota during 2009-2011.
This project will provide analysis of geographic patterns, temporal trends of lake clarity and relationships of water clarity to other lake properties, land cover and demographic factors by use of satellite remote sensing. Data for all lakes and years are available in the LakeBrowser, a web-based mapping tool that enables searches and display of results for individual lakes. This project will extend and add to the database, analyze current and new data, and enhance the capability for resource managers to access and use the data.
The Rice Lake Wetland Nutrient Reduction Project will provide nutrient reductions to downstream recreational water bodies by restoring the Rice Lake Wetland from its current area of 434 acres to pre-ditched water levels of approximately 896 acres.
Numerous studies have shown that stream bank erosion can be a significant contributor to the decline of water quality in the Rock River. The Clean Water dollars provided for this project assisted in three stream bank projects that address the turbidity (muddiness) impairment of the Rock River and bring the river closer to the level of water quality required for the EPA Clean Water Act.The $25,000.00 of Clean Water dollars were successful in leveraging $30,000 of US Fish and Wildlife funding as well as $20,000 of landowner and SWCD investment.
This project aims to mitigate flow and nitrate impacts from agricultural drainage to the Root River through the installation of a suite of multi-purpose drainage management practices.
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.
The purpose of this project is to install a sediment pond along County Ditch #4A to trap sediment and associated pollutants before entering into Bevens Creek which drains into the Minnesota River. Carver County Ditch #4A recently went through a redetermination of benefits process and state law now requires a buffer strip one rod (16.5 feet) wide to be maintained along the top of the ditch bank. The sediment pond, in combination with the buffer strip, will reduce the amount of sediments and pollutants that reach Bevens Creek.
Sherburne County's Local Water Management Plan identifies eutrophication of lakes (heavy algae blooms) caused by excess phosphorus, loss of aquatic vegation, and loss of riparian vegetation. Removal of natural vegetation near the waters edge in developed and agricultural areas has caused loss of fish and wildlife habitat, increased runoff, and allowed bank erosion. The District will address sources of phosphorus and sediment for three important surface waters in the County. In all, phosphorus will be reduced by 355 pounds and sediment will be reduced by 400 tons per year.
Shingle Creek in suburban Hennepin County has experienced significant changes since its days as a narrow, meandering prairie stream. Nearly 100 years ago much of the stream was straightened and dredged to provide better drainage for agriculture. As agriculture gave way to urban and suburban development, Shingle Creek was widened and dredged again to more efficiently convey stormwater to the Mississippi River. Urbanization has resulted in high levels of chloride in the stream from road salt and not enough dissolved oxygen to sustain aquatic life.
The Greater Blue Earth River Basin is a large area within the Watonwan, Le Sueur, and Blue Earth River watersheds. Recent research by University of Minnesota, the National Center for Earth Dynamics, and others has found this basin to be the largest contributor of sediment to Lake Pepin.
The purpose of the project is to reduce sediment and nutrient deposition in surface waters within priority areas of the watershed. A five percent reduction goal has been established in the County Local Water Management Plan and Impaired Waters project in progress. Eleven Best Management Practice (BMP) installations are planned for this project in cooperation with local landowners, Cities, Townships and Lake Associations.
Minnesota Department of Health has been collaborating with cities and other community water suppliers since 1993 to develop and implement source water protection plans. Support from the Clean Water Legacy expands and accelerates the number of water suppliers that can be assisted each year in undertaking protection planning and implementation activities.
Imminent Health Threat (IHT) systems are those that are discharging improperly treated human waste onto the ground surface or into surface waters. In addition to the potential water quality impacts, untreated sewage has the potential to introduce bacteria and viruses into the environment. When IHT systems are identified, county or city staff assist the homeowners through the process required to bring their systems into compliance with the septic ordinance.
Successful long-term treatment of sewage depends on a system capable of providing adequate treatment and effective on-going operation and maintenance. Clean Water Fund Subsurface Sewage Treatment System (SSTS) Program Enhancement funds are used by counties to strengthen programs dedicated to SSTS ordinance management and enforcement. These funds are used for a variety of tasks required to successfully implement a local SSTS program including inventories, enforcement, and databases to insure SSTS maintenance reporting programs.

Clean Water Fund Subsurface Sewage Treatment System (SSTS) Program Enhancement and Inventory funds are to be used by counties to augment available funding dedicated to SSTS ordinance
Nitrate-nitrogen (nitrate) is one of the contaminants of greatest concern for groundwater in Minnesota. This funding is being used for activities that help identify the severity and magnitude of nitrate contamination and implement practices at the local level to reduce nitrate in groundwater. The Minnesota Department of Agriculture (MDA) is working with many local partners and passing funding through to local government units (counties, cities, soil and water conservation districts) to address this concern.
The MDA's technical assistance helps ensure that current and accurate scientific information is made available and used to address water quality concerns in agricultural areas of Minnesota. This funding has been used to evaluate the effectiveness of conservation practices, share information from research and demonstration sites and enhance outreach and education to the agricultural community and local government partners.
