The DNR is working with local communities and an interagency team to define, prioritize, and establish groundwater management areas in Minnesota. Groundwater management areas will have increased data collection and monitoring that allow the state and local communities to understand water supplies, uses, limitations, and threats to natural resources that depend on groundwater. This information will support detailed aquifer protection plans that ensure equitable and sustainable groundwater and drinking water use for the future.
The goal of this project is to apply the Hydrological Simulation Program FORTRAN (HSPF) model to evaluate scenarios to support potential management actions and implementation in the watershed, construct Total Maximum Daily Load (TMDL) studies, and to develop a conceptual site model of the lakes for understanding phosphorus release.
The goal of this project is to construct, calibrate, and validate one fine-scale Hydrological Simulation Program FORTRAN (HSPF) watershed model for the Duluth Watershed Restoration and Protection Strategy (WRAPS) project area for the simulation period 1995–2012. In addition, an existing condition (post-2012 flood) model scenario will be developed for use in WRAPS development. The contractor will produce HSPF models that can readily be used to provide information to support conventional parameter TMDLs.
Minnesota’s use of groundwater has increased over the last two decades. An increasing reliance on groundwater may not be a sustainable path for continued economic growth and development. The DNR is establishing three pilot groundwater management areas (GWMA) to help improve groundwater appropriation decisions and help groundwater users better understand and plan for future groundwater needs associated with economic development.
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 Lake of the Woods (LOW) Total Maximum Daily Load (TMDL) study will: (1) identify water quality goals for the Minnesota portions of the LOW/Rainy River Watershed; (2) recommend nutrient allocations to achieve TMDLs where waters do not meet standards; and (3) provide opportunities for stakeholders to engage in the process of watershed-management planning to adopt protection and restoration strategies. The project will include existing in-lake and watershed model updates, TMDL component development, restoration plan development, and public participation.
The goal of this project is to develop draft Total Maximum Daily Load (TMDL) computations for six impaired lakes and two impaired streams, and to provide TMDL development documentation for selected draft TMDL report sections.
This project supports activities by Minnesota Pollution Control (MPCA) Watershed Division staff that provide technical assistance, project oversight, coordination, outreach and other agency activities associated with assessing, listing and conducting Total Maximum Daily Load (TMDL) studies throughout the State of Minnesota. Project also includes lab analysis, equipment, and fieldwork expenses associated with TMDL work at the MPCA.
The goal of this project is to construct, calibrate, and validate a Hydrologic Simulation Program FORTRAN (HSPF) watershed model for the Otter Tail watershed. The contractor will produce a HSPF watershed model application(s) that can readily be used to provide information to support conventional parameter Total Maximum Daily Loads (TMDLs). The contractor will clearly demonstrate that this model generates predicted output timeseries for hydrology, sediment, nutrients, and dissolved oxygen that are consistent with available sets of observed data.
The goal of this project is to construct, calibrate, and validate a watershed model using the Hydrological Simulation Program FORTRAN (HSPF) model for the Upper/Lower Red Lake Watershed. The contractor will produce an HSPF model that can readily be used to provide information to support conventional parameter Total Maximum Daily Load (TMDL) Studies. The model will generate predicted output for hydrology, sediment, nutrients, and dissolved oxygen that is consistent with observed data.
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 extend the simulation period for the Hydrological Simulation Program - FORTRAN (HSPF) models for the Grand Rapids, Brainerd, Crow Wing, Redeye, Long Prairie, Sartell, Sauk, St. Cloud, and Crow watersheds, and review and comment on the calibration.
This project will extend, calibrate, and validate watershed models using the Hydrological Simulation Program - FORTRAN (HSPF) watershed model for the Mississippi Headwaters, Leech Lake, Pine, and South Fork Crow Watersheds.
The goal of this project is to calibrate, and validate three watershed models using the Hydrological Simulation Program FORTRAN (HSPF) model. The contractor will produce HSPF watershed models that can be further developed to provide information to support conventional parameter TMDLs. The contractor will clearly demonstrate that the models generate predicted output timeseries for hydrology, sediment, nutrients, and dissolved oxygen which are consistent with available sets of observed data.
This project delineates and maps watersheds (drainage areas) of lakes, rivers, streams, and wetlands for the state of Minnesota and provides watershed maps in digital form for use in geographic information systems. These maps become the basis for clean water planning and implementation efforts.
The DNR's Regional Clean Water Specialists and Area Hydrologists work with other state agencies and local partners to help identify the causes of pollution problems and determine the best strategies for fixing them. A statewide coordinator works with the DNR and external partners to ensure funds are spent in the most effective and efficient manner to meet the State's clean water goals.
The DNR provides technical support regarding the causes of and solutions to drainage impacts, actively engaging with other Minnesota modelers and scientists working on issues related to altered hydrology. We use state-of-the-art models to look at cumulative impacts of drainage and land-use practices and determine the benefits of site-specific best management practices. This involves collaboration with multiple partners and at multiple scales.
