The DNR is working with local communities and an interagency team to define, prioritize, and establish groundwater management areas in Minnesota. Groundwater management areas will have increased data collection and monitoring that allow the state and local communities to understand water supplies, uses, limitations, and threats to natural resources that depend on groundwater. This information will support detailed aquifer protection plans that ensure equitable and sustainable groundwater and drinking water use for the future.
This project is studying the response of certain aquifers to groundwater pumping. Research involves an aquifer test, which is an experiment where a well is pumped at a known, constant, pumping rate; changes in groundwater levels and stream flows in the areas around the aquifer test site are observed while the well is being pumped. These tests help us understand how groundwater flows between aquifers, which are underground rock and sand layers that hold water.
Governor Mark Dayton's landmark buffer initiative was signed into law in 2015. The law establishes new perennial vegetation buffers of up to 50 feet along rivers, streams, and ditches that will help filter out phosphorus, nitrogen, and sediment. The new law provides flexibility and financial support for landowners to install and maintain buffers. The DNR's role in Minnesota's new buffer law is to produce a statewide map of public waters and public ditches that require permanent vegetation buffers. The DNR is scheduled to produce these maps by July 2016.
The DNR works with the Minnesota Geological Survey (MGS) to convey valuable geologic and groundwater information and interpretations to government units at all levels, but particularly to local governments, private organizations and citizens. The MGS focuses on geology (Part A reports) and DNR focuses on groundwater (Part B reports). These provide useful information for projects completed by community planners, industry, agriculture, citizens and state agencies related to groundwater.
This is a legislatively mandated project. In order to receive $1,075,000 in water recreation account appropriations for enhancing public water access facilities in FY 2014 and FY 2015 respectively, the commissioner must develop design standards and best management practices specifically for improving water quality by avoiding shoreline erosion and runoff for water accesses.
The DNR works with the Minnesota Pollution Control Agency and the Minnesota Department of Health to determine the level of contamination from mercury and other harmful chemicals in fish from Minnesota's lakes and rivers and to track the success of efforts to reduce mercury pollution. Clean Water Legacy funding is being used to significantly increase (more than double) the number of lakes and rivers that are assessed for mercury contamination on an annual basis. Fish are collected during DNR fishery surveys, processed for laboratory testing, and analyzed for contaminants.
The Minnesota DNR and the Minnesota Forest Resources Council work with forest landowners, managers and loggers to implement a set of voluntary sustainable forest management guidelines that include water quality best management practices (BMPs) to ensure sustainable habitat, clean water, and productive forest soils, all contributing to healthy watersheds. This project will monitor the implementation of these forest management guidelines and BMPs on forested watersheds in MN.
Minnesota’s use of groundwater has increased over the last two decades. An increasing reliance on groundwater may not be a sustainable path for continued economic growth and development. The DNR is establishing three pilot groundwater management areas (GWMA) to help improve groundwater appropriation decisions and help groundwater users better understand and plan for future groundwater needs associated with economic development.
The Index of Biological Integrity (IBI) is a tool that can identify water pollution problems based on the type and abundance of selected plants or animals. The Minnesota Pollution Control Agency (MPCA) uses IBIs for fish and macroinvertebrates (stream-dwelling insects and other critters) in streams to help determine whether these waterways are impacted by water pollution. The DNR has developed a similar tool for fish in lakes and uses a tool for aquatic plants as supporting information on lake biological health.
This project will establish a groundwater monitoring network in the 11 county metropolitan area. The network will provide information about aquifer characteristics and natural water trends by monitoring healthy aquifers (non-stressed systems). The project will also develop an automated system that captures groundwater level and water use data. This system will enhance evaluation of changes in aquifers that are stressed by pumping from existing wells.
This project will create a high accuracy elevation dataset - critical for effectively planning and implementing water quality projects - for the state of Minnesota using LiDAR (Light Detection and Ranging) and geospatial mapping technologies. Although some areas of the state have been mapped previously, many counties remain unmapped or have insufficient or inadequate data. This multi-year project, to be completed in 2012, is a collaborative effort of Minnesota's Digital Elevation Committee and partners with county surveyors to ensure accuracy with ground-truthing.
The DNR has been charged by the legislature to develop rules that protect and manage the Mississippi River Corridor Critical Area (MRCCA) for natural resource, economic development, transportation, historic preservation, and other values. This project engages stakeholder groups in a public process to balance regulatory protections with local flexibility and control.
This project is part of a long-term, collaborative effort that will lead to cleaner water through targeted implementation projects and programs. It will accelerate the adoption of alternative culvert designs that improve biological connectivity and channel stability, reduce the flood stage and lower long-term infrastructure maintenance costs.
The DNR will use its expertise to hatch and grow native freshwater mussels and to restore populations in Minnesota rivers. This project is part of a long-term, collaborative effort that will lead to cleaner water through targeted restoration of native mussel populations. The foundation of the effort is comprehensive assessments of water pollution within the state’s 80 major surface watersheds and prioritized to address these problems.
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.
This project will establish a web-based permitting system to capture essential water appropriation information. The system will include an online permit application process for water use and other permits. The online system will streamline the permitting process for applicants and significantly reduce staff time correcting and managing permit applications and water use reports that are incomplete or have incorrectly calculated permit fees. The use of technology in the application and reporting process will also eliminate staff time needed to enter data and scan and route documents.
The Minnesota Department of Natural Resources (DNR) and Minnesota Pollution Control Agency (MPCA) each collect similar information on streams in Minnesota such as water quality, fish species presence, or the quality of fish habitat. For example, the DNR might sample stream fish to assess whether the agency’s management activities such as fishing regulations or stocking are creating good angling opportunities for the public, while MPCA might sample fish to assess whether a stream meets regulatory standards for a healthy fish community.
Stream flow information is essential for understanding the state of Minnesota's waters. Clean water funding has allowed the DNR to expand a network of stream gages that support planning and implementation for clean water protection and restoration. These gages are also used as part of the interagency Flood Forecasting/Warning System. This expanded stream gaging network has also significantly increased the real time data available to recreational water enthusiasts via the internet.
This initiative is for the design and implementation of projects in Wildlife Management Areas (WMAs), or other state administered lands that increase water storage while also stabilizing streambanks in impaired watersheds where watershed restoration and protection strategies or comprehensive watershed management plans developed under the One Watershed, One Plan program have identified the need for water storage and water quality improvements.
DNR regional clean water specialists and area hydrologists work with regional staff from other state agencies and with local partners to help identify the causes of pollution problems and determine the best strategies for fixing them. We collect and analyze stream channel stability and streambank erosion data to help identify root causes of certain water quality impairments in streams.
The Watershed Health Assessment Framework (WHAF) is a web-based tool for resource managers and others interested in the ecological health of Minnesota's watersheds. The framework uses five ecological components to organize and deliver information about watershed health conditions in Minnesota. The five components are hydrology, connectivity, biology, geomorphology, and water quality. Statewide GIS data from DNR and partner agencies are used to calculate health scores that reveal similarities and differences between watersheds.
The DNR provides technical support related to the causes of altered hydrology and watershed management solutions. We use state-of-the-art models and statistical methods to look at cumulative impacts of drainage and land-use practices and determine the benefits of best management practices. This involves collaboration with multiple partners at multiple scales.
This project delineates and maps watersheds (drainage areas) of lakes, rivers, streams, and wetlands for the state of Minnesota and provides watershed maps in digital form for use in geographic information systems. These maps become the basis for clean water planning and implementation efforts.
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.
