A cooperative study was conducted by the U.S. Geological Survey (USGS), the Metropolitan Council, and the Minnesota Department of Health to assess groundwater and surface-water interactions in lakes in the northeast Twin Cities Metropolitan Area (TCMA), including White Bear Lake. An important product of the study was the creation of a groundwater-flow model focused on the northeast TCMA. The groundwater flow model is available for future use to assess the effects of groundwater withdrawals on lake levels as well as to describe other groundwater and surface-water interactions.
The goals of the program are to evaluate the effectiveness of agricultural conservation practices, identify underlying processes that affect water quality, and develop technologies to target critical areas of the landscape. Funded projects provide current and accurate scientific data on the environmental impacts of agricultural practices and help to develop or revise agricultural practices that reduce environmental impacts while maintaining farm profitability.
USGS will complete the following activities in support of the SCSU project Assessing the Contribution of Microhabitat Differences on Biological Effects in Bluegill Sunfish in Sullivan Lake, MN-Continuation of MN Lakes Study 2010-2011. Geospatial analysis of maps, aerial photography, satellite imagery, GIS data, and field mapping (topography, bathymetry, vegetation, habitat); Bulk characterization of the physical and chemical features of the littoral zone, inflows, and outflows.
This project will evaluate and prioritize approximately 13,000 lineal feet of Lake Koronis shoreline for shoreline erosion and vegetative buffer condition. Those property owners with the most erosion, stormwater and vegetative buffer issues will be targeted to stabilize, infiltrate and buffer their shoreline. This project will also evaluate an additional 300 properties in the subcatchment area and target those properties that are best able to capture and treat stormwater from impervious surfaces.
The Twin Cities metropolitan area has a rich history and connection with its waters. In an effort to keep surface waters clean, a wide variety of stormwater practices have been developed and installed throughout the metro in recent years. Many of these, such as rain gardens and infiltration basins and trenches, are intended to reduce the total runoff volume by infiltrating stormwater. Six to seven aquifers underlie the metro area and provide residents with drinking water.
The goals of Phase I of the Marsh River Watershed (WRW) Watershed Restoration and Protection Strategy (WRAPS) project are to: 1) gather or develop watershed data needed for the development of the WRAPS project; 2) establish project and sub-basin work groups, develop a social outcomes strategy, and develop a civic engagement evaluation strategy to guide the WRAPS project; and 3) begin to identify, create, and organize tools that can be used to determine potential stressors and priority management areas.
The goal of this project is to better target restoration activities in the Cannon River watershed via a paleolimnological study of a selected set of the lakes addressed in the Total Maximum Daily Load (TMDL) for the watershed. The goals are to better constrain lake phosphorus budgets, and determine the magnitude of ecological change experienced by a range of lake types.
The objective of the project is to demonstrate controlled drainage and saturated buffers as flood mitigation practices as well as their water quality and quantity benefits. The project is intended to set a compelling example to increase the acceptance and adoption of drainage water management practices in the Red River Valley.Surface and subsurface runoff will be monitored, and water samples will be collected and analyzed for nitrate-nitrogen. Installations were completed in 2015-2016.
The Metropolitan Council, in conjunction with the University of Minnesota, is evaluating outdoor water use in the Twin Cities metro region - a subject which has come under the spotlight recently due to concerns related to water quality and quantity issues. In the Twin Cities, 20% of all treated drinking water is used outdoors, with a majority of this being used on lawns and landscapes. The goal of this proposal is to reduce water use in the home landscape by conducting assessments, research, and demonstration around the smart use of irrigation.
The Root River Field to Stream Partnership is comprised of farmers, the Minnesota Department of Agriculture, the Minnesota Agricultural Water Resource Center, The Nature Conservancy, Fillmore and Mower County Soil and Water Conservation Districts, the Root River SWCD, Monsanto and academic researchers.Together, project partners are addressing the following key questions:What is the range of sediment, nitrogen and phosphorus losses from agricultural fields on real farms in southeast Minnesota?What are the long-term trends and relationships between specific farming practices and water qualit
The purpose of the project is to collect data to represent the ambient condition of the lakes and streams of the Rum River Watershed within Mille Lacs, Isanti and Sherburne Counties that is needed to determine if thresholds set to protect designeated uses, such as aquatic recreation and aquatic life, are being met .
The goal of this project is to investigate nitrate transport and the sources of nitrate in karst for more effective implementation of best management practices that will reduce nitrate concentrations in ground and surface water.
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 and Inventory 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.
Turbidity and sediment yield from the Le Sueur River watershed to the Minnesota River is a problem. Studies have shown that 200,000 tons/yr come from non-field sources and 25,000 tons/yr come from field sources. With this grant we will develop strategies to reduce sediment yield from the Freeborn County Cobb River Ditch subwatershed.
