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.
The goal of this project is to construct, calibrate, and validate two Hydrologic Simulation Program FORTRAN (HSPF) watershed models: Lake Superior North and Lake Superior -South. The contractor will produce HSPF models that can readily be used to provide information to support conventional parameter Total Maximum Daily Loads (TMDLs). The contractor will clearly demonstrate that these models generate predicted output timeseries for hydrology, sediment, nutrients, and dissolved oxygen which are consistent with available sets of observed data.
The goal of this project is to continue and finalize Hydrological Simulation Program FORTRAN (HSPF) watershed model construction and complete the calibration/validation process. The consultants will produce HSPF watershed model applications for the Lake Superior North and Lake Superior South watersheds that can readily be used to provide information to support conventional parameter Total Maximum Daily Load (TMDL) projects.
Concern for Deer Yard and Poplar lakes centers on their current trends of decreasing water transparencies often associated with phosphorus or sediment increases. Although both lakes still meet nutrient goals, trends in Secchi depth may presage emerging issues with the state of the lakes. This has further led to questions whether the productivity of the lakes have changed over time, what the natural or historical condition of the lakes were, what the current trajectory of each lake is, and how to best set management goals.
This project will complete the Total Maximum Daily Load (TMDL) study and Watershed Restoration and Protection Strategies (WRAPS) for the Lake Superior North watershed. Two segments of the Flute Reed River are impaired for aquatic life due to elevated turbidity and total suspended solids. The lower Poplar River is also listed as impaired but significant progress has occurred in the last 10 years. A TMDL and implementation plan have been completed for the lower Poplar River impairment. All other waters meet water quality standards and will be considered for protection measures.
Approximately 70 percent of all Minnesotans rely on groundwater as their primary source of drinking water. Wells used for drinking water must be properly sealed when removed from service to protect both public health and Minnesota’s invaluable groundwater resources. The Minnesota Department of Health protects both public health and groundwater by assuring the proper sealing of unused wells.
Clean Water funds are being provided to well owners as a 50% cost-share assistance for sealing unused public water-supply wells.
The Metropolitan Council, in conjunction with CDM Smith and HKGi consultants, reorganized and expanded the water conservation tools on the water supply planning pages of the Metropolitan Council’s website. The revised toolbox was organized into an online, web-based guide format. These tools are supplemented with fact sheets and case studies that serve to educate and provide useful information to support water conservation programs and activities.
