The Minnesota County Geologic Atlas program is an ongoing effort begun in 1982 that is being conducted jointly by the University of Minnesota's Minnesota Geological Survey and the Minnesota Department of Natural Resources (DNR). The program collects information on the geology of Minnesota to create maps and reports depicting the characteristics and pollution sensitivity of Minnesota's ground-water resources.
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.
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.
Project Outcome and Results
The Metro Conservation Corridors (MeCC) Partnership completed its fifth phase of work to accelerate protection and restoration of remaining high-quality natural lands in the greater Twin Cities metropolitan area. Work was accomplished by strategically coordinating and focusing conservation efforts within a connected network of critical lands that stretches from the area's urban core to its rural perimeter, including portions of 16 counties.
The Minnesota Land Trust provides coordination, mapping, and data management for the Metropolitan Conservation Corridors partnership. Funds are being used to coordinate the partnership, guide strategic outreach and implementation efforts, manage project data, and provide reporting and mapping of accomplishments.
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 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.
