This project will develop and execute three point source related scenarios for the Chippewa River watershed using an existing HSPF watershed model. This project will also support the review of the HSPF Modeling Guidance Document.
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 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.
The goal of this project is to extend the existing HSPF models through 2012 in the Chippewa Watershed (07020005) and Hawk-Yellow Medicine Watershed (07020004) to incorporate recent monitoring data to support current MPCA business needs and sediment source investigations.
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 goal of this project is to continue and finalize Hydrological Simulation Program FORTRAN (HSPF) watershed model construction and complete the calibration/validation process for the Minnesota River–Headwaters and Lac qui Parle watersheds that can readily be used to provide information to support conventional parameter Total Maximum Daily Load (TMDL) reports.
The Minnesota River Basin Hydrological Simulation Program FORTRAN (HSPF) models simulate sediment erosion and transport, however these models periodically need to be adjusted to be consistent with the most recent sources of information regarding sediment distribution and loading rates. The goal of this project is to refine the sediment source partitioning and simulation in the Minnesota River basin using all relevant available sources of information.
The Minnesota River Basin Hydrological Simulation Program FORTRAN (HSPF) models, which simulate flow and pollutant transport, need to be refined to be consistent with the most recent external sources of land use, hydrologic response, and surface flow attributions. The primary goal of this work is to refine the hydrologic calibration in the Minnesota River basin.
The goal of this project is to establish load reduction requirements for impaired waters and to develop restoration strategies to improve water quality for impaired waters and protection strategies to maintain the quality of water for water bodies meeting standards.
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 extend existing Hydrologic Simulation Program FORTRAN (HSPF) models through 2017 for the following major watersheds: Redwood, Cottonwood, Watonwan, Blue Earth, Le Sueur, Pomme de Terre, Minnesota River-Headwaters, and Lac Qui Parle watersheds.
The goal of this project is to refine the nutrient and algae simulation in the Minnesota River basin using all relevant available sources of information. The outcome of this work order is a revised Hydrological Simulation Program – FORTRAN (HSPF) watershed model application for the Minnesota River basin that correctly represents nutrient sources and algae.
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.
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.
