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.
