These fully functioning calibrated validated executable models will simulate hydrology, sediment (sand, silt, and clay), temperature, phosphorus, nitrogen, dissolved oxygen, biochemical oxygen demand, and algae at the 12-digit HUC subbasin scale (or finer).
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.
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 these major watersheds: Crow Wing River, Redeye River, and Long Prairie River.
This project will continue HSPF watershed model construction beyond the initial framework development. The consultant will add representation of point source discharges to the model. The consultant will also compile flow data for the purposes of calibration and validation. Finally, an initial hydrologic calibration will be performed and submitted for approval.
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.
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.
This project will complete the final Implementation Plan, semi-annual and final reports and hold project meetings. The Implementation Plan will identify target areas and priorities for implementation strategies to improve water quality for Bluff Creek. This project will build the groundwork so Bluff Creek will meet water quality standards for aquatic life in the future.
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.
The Metropolitan Council and City of Saint Paul cooperated on a rainwater harvesting and reuse system in downtown Saint Paul. Rainwater from the northern half (2 acres) of the roof at the new Metro Transit Green Line Operations and Maintenance Facility (OMF) is captured using a modified version of the existing OMF rainwater collection system. The existing collection system was re-designed to convey rainwater to the new Lowertown Ballpark, home of the Saint Paul Saints, where uses include ball field irrigation and toilet flushing.
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 provide the MPCA and all local partners in the Twin Cities Metropolitan Area (TCMA) the information and tools necessary to improve and/or maintain water quality with respect to chloride for the 7-county metropolitan area during the winter maintenace period.
This project will provide modeling services to support the completion of the Typo Lake and Martin Lake Excess Nutrients TMDL report. A Total Maximum Daily Load (TMDL) report quantifies pollutant levels, identifies sources of pollution, and proposes ways to bring water quality back to an acceptable level.
State law charges the Metropolitan Council (Council) with developing and maintaining a base of technical information needed for sound water supply decisions (Minnesota Statutes 473.1565). The Council’s primary tool to provide this information is the Metro Model 2, a regional groundwater model capable of predicting the impacts of planned water demand on aquifers and connected lakes and streams. The Metro Model 2 is a modern and comprehensive groundwater model of the Twin Cities area, but it is currently out-of-date.
Regional recharge modeling with the Twin Cities daily soil water balance (SWB) model has been a fundamental part of the Metropolitan Council’s groundwater flow modeling effort and supports the Metropolitan Area Master Water Supply Plan. The SWB model is used to evaluate the impact of planned and potential land use and climate on recharge in the eleven-county metropolitan area, and supports the ongoing update of the regional groundwater flow model.
Project goal is to develop Total Maximum Daily Loads (TMDLs) and Watershed Restoration and Protection Strategies (WRAPS) that will protect and improve water quality for the Minnesota portion of the Mississippi River–Reno and Upper Iowa River watersheds. This information paired with other tools (e.g. Hydrologic Simulation Program FORTRAN (HSPF) models and best management practice spreadsheets) and will support restoration and protection strategy development and prioritization efforts in the 1W1P area.
