This project will accelerate production of County Geologic Atlases (part A). This is a set of geologic maps and associated databases for a county that facilitate informed management of natural resources, especially water and minerals.

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.
On behalf of the Metropolitan Council, Barr Engineering Company developed maps and supporting information to characterize the relationship between surface waters and groundwater, identifying surface waters most likely to be impacted by groundwater withdrawals in the region. This project also provided guidance on effective resource monitoring strategies and costs for each type of surface water feature.
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.
On behalf of the Metropolitan Council, the Minnesota Geological Survey evaluated the vulnerability of glacial aquifers in the Twin Cities metropolitan area. The project improved upon previous vulnerability assessments by incorporating a substantial amount of new aquifer property information and blending methods previously used by the Minnesota Departments of Health and Natural Resources. The result is a consistent vulnerability assessment across the metropolitan area based on the most up-to-date information available.
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.
The Minnesota Department of Natural Resources will coordinate the collection of high-resolution elevation data for northeastern portion of Minnesota using Light Detection and Ranging (LIDAR) systems. The geographic area of the work includes Minnesota counties of Carlton, Cook, Lake, and St. Louis Counties and that portion of Koochiching County that comprises Voyageurs National Park.
This project will support the MPCA’s water quality monitoring and assessment program. Specifically, the MPCA is developing a refined use designation process known as tiered aquatic life uses (TALU) to account for situations in which stream habitat has been compromised through hydrological alteration (e.g. channelization and ditching). An accurate state-wide determination of altered stream segments based upon the current National Hydrography Dataset (NHD) linework will assist in the assignment of the correct beneficial use within this new TALU framework.
This project will develop a surficial geology shapefile (map) for part of the State of Minnesota, by modifying and joining smaller existing, but separate, surficial geology maps. The resulting internally consistent geographic information system (GIS) layer will be used to support the hydrologic parameterization of Minnesota Pollution Control Agency (MPCA) watershed models.
The Watershed Health Assessment Framework 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.
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.
