This monitoring work expands on previously established routine water quality and flow sampling to include extensive fish and aquatic invertebrate surveys. Subsequent steps include assessment of the monitoring data to determine impairments, identification of stressors that are causing impairments, development of Total Maximum Daily Load (TMDL) studies using identification of pollutant sources using computer modeling and other techniques, civic engagement, and public education as approaches in progress towards water quality goals.
This project will apply science to identify viable and priority wetland restorations and rehabilitations that will deliver sustainable water quality benefit, along with flood storage and habitat benefits. Decision tools will be developed to assist with selection of restoration projects.
Whaletail Lake (MDNR 27-018400) is located within the jurisdictional boundaries of Pioneer-Sarah Creek Watershed Management Commission (PSCWMC). The lake is considered having two distinct basins relative to the Minnesota water quality nutrient standards with the South basin (MDNR 27-018402) classified as a deep lake (156 acres; max depth 23 feet; & 66% littoral) and the North basin (MDNR 27-0180401) classified as a shallow lake (370 acres; max depth 10 feet; & 100% littoral).
This project will support the operation and maintenance of a stream gage that records stage, index-velocity and water temperature at Wheeler's Point on the Rainy River. The USGS will visit the stream gage approximately every six (6) weeks to perform maintenance and, as needed, to define the range of flows that occur.
The Whiskey Creek project involves a coordinated and comprehensive approach to watershed management. This project consists of installing conservation practices that reduce sediment loading to Whiskey Creek while also providing flood reduction benefits to downstream landowners.
The Wilkin Soil and Water Conservation District will partner with the Buffalo Red River Watershed District, the Natural Resources Conservation Service, and landowners to install 59 side inlets to stabilize high priority gullies that are contributing sediment to Whiskey Creek. When these 59 gullies are stabilized, sediment loading to Whiskey Creek will be reduced by an estimated 1,006 tons per year and total phosphorus reduced by 794 pounds per year.
The Whiskey Creek Watershed is the largest subwatershed in the Upper Red River of the North drainage, encompassing 165.63 square miles in Otter Tail and Wilkin Counties. This watershed contains the headwaters of the Red River of the North, which begins in far west central Wilkin County, an area of mixed residential and agricultural land use. The cities of Breckenridge, Minnesota and Wahpeton, North Dakota, as well as the small town of Kent are within the watershed.
The DNR is directed by Minnesota Law 2016, Chapter 172, Article 2, Section 12 to request proposals for a potential design-build project to augment White Bear Lake with water from East Vadnais Lake.
Within Whitewater River Watershed, groundwater is the primary drinking water source for both private and community wells. These drinking water aquifers often lack adequate protective layers making them vulnerable to contamination. Unused wells can deteriorate and pose a serious risk to groundwater quality by providing a pathway for contaminants from the surface to easily travel into groundwater. This project will use cost-share funds to incentivize sealing twelve abandoned wells that are contamination risks to vulnerable aquifers.
Project outcomes include results from hydroponics experiments, which will likely consist of information on the response of wild rice growth to a range of concentrations of sulfate, sulfide, and various cations. Results from these experiments will be used to help determine what additional research is needed in 2013. The MPCA will use this data to evaluate the current sulfate standard and the need, if any, for modifications to it.
Project outcomes include data that will ultimately allow the MPCA to quantitatively compare the environmental conditions (surface water and sedimentary geochemistry) at sites that successfully support wild rice growth to sites that do not support wild rice. These data, in particular the analysis of the porewater samples obtained under this project, will be compared to the results from a separate project that will assess the growth of wild rice using hydroponic methods.
The MPCA is currently collecting additional information needed to evaluate the 10 mg/liter wild-rice-based sulfate standard and has received funding through legislation passed during the 2011 Special Session to implement a wild rice research plan and contract with scientific experts to further understand the effects of sulfate on the growth of wild rice. The goal of this project is to determine responses of wild rice to sulfate and the products of geochemical transformations of sulfate.
This project makes an additional plant growth chamber available to increase efficiency for the MPCA Wild Rice Standards Study, which is gathering information about the effects of sulfate on the growth of wild rice.
The goal of this project is to collect and analyze samples from lake, stream, wild rice paddy, and experimental field sites across a spectrum of sulfate concentrations and wild rice plant abundance. The scientific information developed will be part of the evidence used by the MPCA in its decision as to whether or not a change to the existing sulfate standard is necessary, and if so, what the revised standard should be.
The MPCA is undertaking a study to investigate the potential effects of elevated sulfate on the growth of wild rice. One high-priority hypothesis is that the conversion of sulfate to sulfide in anoxic subsurface sediment may harm the roots of wild rice, either directly, or indirectly. The goal of this project is To observe and develop an understanding of exposure of wild rice roots to changes in concentration of sulfide and related chemicals over time and space (depth of sediment and distance from roots).
This project will provide lab analyses and interpretation required for 2012 wild rice field survey. The 2012 lab analyses will be merged with the 2011 field survey data and determine what additional work, if any, is needed during the 2013 field season.
The MDH Environmental Laboratory provides essential analyses of water for the MPCA Wild Rice Standards Study, which is gathering information about the effects of sulfate on the growth of wild rice. For this study, the lab developed a ultra-sensitive test for hydrogen sulfide, which greatly facilitated the research. For this large study, the lab staff analyzed several thousand water and sediment samples from lakes, wetlands, rivers, rice paddies, experimental mesocosms, and hydroponic experiments.
This project builds on the successful implementation of previous work, installing 29 water and sediment control basins and 25 acres of vegetative filter strips within the priority Marsh Creek watershed to reduce sediment loading into the Wild Rice River, which is currently not meeting water quality standards for sediment.
Phase 2 of the Wild Rice River Watershed Restoration and Protection Strategy (WRAPS) project includes: continued civic engagement; production of the Total Maximum Daily Load (TMDL) study, which allocates pollutant load reductions for impaired waters; and production of the WRAPS report, which identifies implementation strategies that will maintain or improve water quality in many lakes and streams throughout the watershed.
Assesss current data sources and preliminary information about the conditions in the watershed and present the information through bibliographies, abstracts and memos.
A total of 62 grade stabilization structures and 13.5 miles of continuous berms will be constructed and become a permanent part of County Ditches 9 and 10. An additional 100 acres of buffers will be seeded beyond those required by law. Together these practices will reduce peak flows into the county ditches, provide better erosion control, reduce sediment, improve water quality and reduce future drainage system maintenance costs. The project will reduce 595 tons of sediment per year from the CD 9 & 10 watersheds to the Rabbit River. This is 18 percent of the Rabbit River TMDL goal.
This grant will fund about 45 projects in High Groundwater Priority areas, High Surface Water Priority area, and/or in sub-watershed with stressed/impaired streams for the four WinLaC planning regions. These practices will reduce overland total nitrogen loading and loading to groundwater; reduce overland total phosphorous and sediment; and increase headwater storage and/or reduce peak flow rates and sediment loading.
The WinLaC Prioritization and Public Participation Project will identify priority water quality issues and concerns for the watershed approach in the Mississippi River - Winona and La Crescent watersheds. Information obtained from this project will help develop the Watershed Restoration and Protection Strategy (WRAPS) Update report as well the WinLaC Comprehensive Watershed Management Plan.
This project will continue the development of a Pre-Watershed Restoration and Protection Strategy (WRAPS) assessment, evaluation, community outreach and involvement, and development project that will provide for a comprehensive and more successful watershed restoration approach.
This project will produce a final Total Maximum Daily Load (TMDL) report and Watershed Restoration and Projection Strategy (WRAPS) reports for the Winnebago and Mississippi River – La Crescent watersheds including the drafting of public notice versions of the reports, responding to comments during the public notice period and producing the final TMDL and WRAPS reports.
The Winona County Well Sealing Costshare Program will utilize Clean Water Funds to speed water well sealing in a continuing effort to protect the groundwater aquifers used for drinking water in Southeast Minnesota. Since 1990, 1303 unused water supply wells have been sealed in Winona County with costs ranging from $500-$10,000+ per well.
This project will produce a Winter Maintenance Assessment tool prototype that allows users to create a customized approach to modify their existing winter maintenance program that will reduce their road salt use. The tool will allow users to take inventory of their current practices and evaluate how they are doing today and where they have the most potential to reduce salt usage.
The goal of this project is to maintain and make enhancements to the Winter Maintenance Assessment tool (WMAt), which is a necessary technical resource and planning tool for stakeholders and permittees to implement the chloride reduction strategies described in the Chloride Management Plan. The WMAt is critical for assisting stakeholders in meeting the water quality goals of the Chloride Management Plan without compromising public safety, and allowing for consideration of the varying resources and conditions for each individual winter maintenance program.
