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.
This project will support the collection and analysis of sediment core samples, from each of the five bays ( Little Traverse, Big Traverse, Muskeg, Sabaskong and 4-Mile Bays), to ensure adequate characterization of the P fluxes from deposited sediment and equilibrium P fluxes from re-suspended sediment.
This project Phase will collect data, background information, and watershed characteristics within the Red Lake River watershed. This information will be documented within the framework of early draft TMDL Reports (with background information, but no load calculations) for impaired reaches within this watershed and early draft protection plans for the areas in the watershed that are not currently impaired.
This first phase of project will define the existing watershed conditions; identify gaps in existing data; design and implement a plan to address data gaps; incorporate gap data into watershed description; guide development of the HSPF model; establish citizen advisory, technical advisory and locally-based focus groups; research and design an education and outreach strategy; and design and deploy the tools and methods to employ the strategy.
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.
This project will finalize HSPF watershed model construction and complete the calibration/validation process for the following three watersheds: North Fork Crow River, South Fork Crow River, and Sauk River.
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.
This project will determine pre- and post-settlement nutrient trends from sediment chronology, fossil diatom assemblages, and from sediment profiles representing human history in the region (i.e., at least 150 years). Project activities include sample collection; sample preparation; diatom analysis; database creation and management; and data interpretation. Sample cores will be taken on the Lake of the Woods in five major bays (i.e., Four-mile, Muskeg, Sabaskong, Little Traverse, and Big Traverse) in the southern basin.
This project will support the collection of water-quality samples and gauge streamflow near the mouths of the Rainy and Warroad Rivers; collect water-quality samples at 10 sites in LOW; and measure streamflow velocities and cross-sectional areas of 5 channel constrictions in LOW.
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 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).
