The State Fiscal Year 2014-2015 Clean Water Fund appropriation identified the northeast metro as an area where potential solutions are needed to address emerging water supply issues. The Metropolitan Council, in conjunction with S.E.H. consultants, evaluated water supply approaches to serve the northeastern part of the Twin Cities metropolitan area. A subregional study areas was selected based on the indication of potential problems with the long-term sustainability of current water supplies, as well as expressed interest by community stakeholders.
The State Fiscal Year 2014-2015 Clean Water Fund appropriation identified the northeast metro as an area where potential solutions are needed to address emerging water supply issues. Three projects are underway to identify the advantages and disadvantages of combining water supply systems, using new water supply sources such as treated water from Saint Paul Regional Water Services or raw water from the Mississippi or St. Croix rivers, and optimizing groundwater pumping to protect water levels in White Bear Lake and other lakes across the northeast metro.
This project will finalize HSPF watershed model construction and complete the calibration/validation process. The consultant will add representation of point source discharges to the model. The consultant will compile flow data for the purposes of calibration and validation. An initial hydrologic calibration will be performed and submitted for approval.
The goal of this project is to construct, calibrate, and validate three HSPF watershed models. The project will result in HSPF models that can readily be used to provide information to support conventional parameter TMDLs. The models are expected to 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 supplement and refine the Deer Creek Watershed TMDL Report and Implementation Plan project with detailed determinations of critical source areas and prioritization of the associated management practices, facilitated by additional meetings with local resource managers and validated with a field survey.
