On behalf of the Metropolitan Council, Environmental Financial Group Inc. generated a matrix of water conservation programs with detailed information about the costs and benefits of the programs. Tools were also developed to allow users to calculate potential water savings, estimate program implementation costs, and test the effects of various water conservation programs and rate structures.
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 collected information and conducted an assessment of the hydraulic properties and chemistry of selected aquifers in the metro area. This project greatly improves the accessibility of existing data, which were previously available only in scattered paper reports. A robust database of groundwater age, aquifer hydraulic conductivity and groundwater chemistry data was developed to make the information easily accessible to water resource managers.
In 2005, Metropolitan Council was directed to carry out regional water supply planning activities under Minnesota Statutes, section 473.1565. Working closely with the region's many water supply stakeholders and under the guidance of a metropolitan area water supply advisory committee, Metropolitan Council developed and adopted a metropolitan area master water supply plan (master plan) in 2010. The plan provides a framework for water supply planning and identifies actions needed to achieve the goal of ensuring sustainable water supplies across the region.
Phase 4 of the Lake Winona Total Maximum Daily Load (TMDL) project will finalize the draft Lake Winona TMDL, dated November 2009, by completing additional data analysis, lake quality modeling, updating the TMDL report, and supporting the public involvement process.
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.
