This project will develop a Final TMDL report and Implementation Plan for the Bluff Creek Watershed. The main outcomes of this project are the development of a Final TMDL Report approved by MPCA and EPA and a Final Implementation Plan approved by MPCA.
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.
This project will complete spatial and temporal revisions of 6 Hydrologic Simulation Program FORTRAN (HSPF) models, the recalibration and validation of 7 watershed HSPF models, and the revision of the drainage network and point source representation of the Pomme de Terre HSPF model.
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.
Having current and accurate data on historic and archaeological sites is important to understanding our past and to preserving Minnesota’s history for future generations. In 2010-2011, the Minnesota Historical Society awarded contracts for these survey projects:
This project will complete a chloride management plan which will lay out a strategy for addressing chloride impacts to our surface waters for the 7-county metropolitan area. This chloride management plan will satisfy EPA requirements for impaired waters, address waters not yet listed, and develop a strategy to protect waters that are currently meeting the water quality standards.
This project will develop a watershed restoration plan that provides quantitative pollutant load reduction estimates and a set of pollutant reduction and watershed management strategies to achieve water quality standards for all impairments within the watershed. It will also an important framework for civic and citizen engagement and communication, which will contribute to long-term public participation in surface water protection and restoration activities throughout the watershed.
This project will support the monitoring of reaches where there are data gaps, incorporate new data and relevant data, continue identification of pollutant sources, complete load duration curves, coordinate and encourage participation in stakeholder meetings. The information gathered during Phase IIB will be utilized towards the development of a Draft Restoration (TMDL) and Protection Plan (Plan).
