This project will complete a pollutant source identification and subwatershed information report and support the development of a Draft Restoration and Protection Plan (RAPP). It will also support the devlopment of a Implementation Plan that will identify target areas for BMP implementation for bacteria reductions.
The goal of this project is to develop a phosphorus TMDL for the six impaired lakes in the southwest portion of the Rice Creek Watershed District; Island Lake, Little Lake Johanna, Long Lake, East Moore Lake, Pike Lake and Lake Valentine.
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.
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.
The goal of this project is to construct, calibrate, and validate five Hydrologic Simulation Program FORTRAN (HSPF) watershed models. The outcome will be HSPF models that can readily be used to provide information to support conventional parameter TMDLs. These models will generate predicted output timeseries for hydrology, sediment, nutrients, and dissolved oxygen which are consistent with available sets of observed data.
This project will support construction of three watershed framework models built using the Hydrologic Simulation Program FORTRAN (HSPF). These executable models will simulate hydrology at the subbasin scale. An HSPF model will be built for each of three major watersheds: the Crow River/North Fork Crow River, the South Fork Crow River, and the Sauk River.
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.
The goal of this project is to refine the segmentation, extend the simulation period, and recalibrate an existing Hydrologic Simulation Program FORTRAN (HSPF) watershed model for the Rum River Watershed.
The consultant LimnoTech will support response to Total Maximum Daily Load (TMDL) comments the peer review process, United States Environmental Protection Agency and public notice. They will then revise the TMDL document as needed and attend internal and external project meetings.
The goal of this project is to finalize the Lake Pepin Watershed phosphorus total maximum daily load (TMDL) report by using the existing information and documentation prepared under previous contracts to prepare one TMDL report that addresses the impairments on the mainstem of the Mississippi River. Information developed to date for draft TMDLs on the Minnesota River mainstem will be documented for later use by the Minnesota Pollution Control Agency.
This project is for a contract with Emmons & Olivier Resources Inc to develop Total Maximum Daily Loads (TMDLs; a federal clean Water Act requirement) and a Watershed Restoration and Protection Strategy (WRAPS) report for the for Mississippi River - LaCrescent and Winnebago River watersheds.
The Metropolitan Council, in conjunction with HDR Engineering, Inc. consultants, will evaluate a variety of approaches to develop sustainable water supplies across the metro area. Subregional study areas are being selected where multiple communities face potential problems with the long-term sustainability of current water supplies, and where community stakeholders have expressed interest in learning more about sustainable water supply options.
As the Metropolitan Council updated the Twin Cities Metropolitan Area Master Water Supply Plan, stakeholders asked the Council to consider the sustainable limits of the region’s water sources. The Council’s most important analytical tool is a regional groundwater flow model (Metro Model 3), which can be used to quantify the long-term regional impacts caused by hundreds of independent groundwater appropriations.
The goal of this project is to complete the construction, calibration, and validation of an Hydrological Simulation Program FORTRAN (HSPF) watershed model for the Minnesota portions of three watersheds: Root River, Upper Iowa, and Mississippi River-Reno.
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 goal of this project is the continued development of an overall strategy for reduction of turbidity/TSS, with sets of sediment reduction initiatives and actions for various sources, to address the Minnesota River Turbidity TMDL and the South Metro Mississippi River TSS TMDL. The overall strategy will be used to help establish a path towards achieving the required reductions of turbidity/TSS.
