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.
This project will promulgate a nitrate water quality standard to address aquatic life toxicity, and gather information needed to support the development of total nitrogen (N) loading reduction strategies for Minnesota’s waters and also address Minnesota’s contribution to marine water hypoxia. Project will also develop a framework for a watershed nitrogen planning aid that can be used to optimize selection of Best Management Practice (BMP) systems for reducing nitrogen.
This project will construct three watershed framework models built using the Hydrologic Simulation Program FORTRAN. These executable models will simulate hydrology at the 12-digit HUC subbasin scale. An HSPF model will be built for each of the following 8-HUC watersheds: Red Lake River (09020303) and the Clearwater River (09020305).
This project will finalize HSPF watershed model construction by incorporating internal phosphorus loading in modeled lakes, run a suite of implementation scenarios and generate a GenScn project containing model output. The consultant will produce HSPF watershed models that can readily be used to provide information to support conventional parameter TMDLs. The consultant will deliver all modeling files for baseline and implementation scenarios and provide a GenScn project containing model output.
The goal of this project is to enhance the current version of the Enhanced Expert System for Calibration of HSPF (HSPEXP+) so that it can more easily and quickly be used for hydrology calibration, water quality calibration, generate reports and graphs.
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 develop the guidance needed for water quality parameter evaluation and calibration for Hydrological Simulation Program – FORTRAN (HSPF) applications that utilize the general water quality constituent routines on the land surface to generate loadings of nutrients and organic material for input to water bodies to support dissolved oxygen (DO), nutrient, and algal simulation.
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 a guidance document for the construction of Hydrologic Simulation Program FORTRAN (HSPF) watershed models which are intended to support MPCA Watershed programmatic activities. It will also customize and populate a national HSPF parameter database with values from Minnesota HSPF model applications. This enhanced database will expedite the future construction of HSPF models as well as increase the consistency among HSPF model applications in Minnesota.
This project supports activities by MPCA Watershed Division staff that provide technical assistance, project oversight, coordination, outreach and other agency activities associated with assessing, listing and conducting TMDL studies throughout the State of Minnesota. Project also includes lab analysis, equipment, and fieldwork expenses associated with TMDL work at the MPCA.
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.
This project will provide an interpretive assessment of nitrogen concentrations in Minnesota rivers and streams, including spatial and temporal trends based on historical data sets. The trends analyses will provide information useful for evaluating nitrogen reduction efforts in the past couple of decades.
The goal of this project is to complete the construction, calibration, and validation of a Hydrological Simulation Program FORTRAN (HSPF) watershed model for the Otter Tail River 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.
The goal of this project is to extend, calibrate, and validate the existing Hydrological Simulation Program – FORTRAN (HSPF) watershed models in the Red Lake River, Thief River, Clearwater River and Red Lake watersheds.
The contractor will collect and process the necessary files needed to develop a Processing Application Tool for HSPF (PATH) and Scenario Application Manager (SAM) project for 30 HUC 8 watersheds in Minnesota. SAM provides a graphical interface to the Hydrological Simulation Program FORTRAN (HSPF) model applications and expands the state’s investment in HSPF to a broader audience in support of the development of Total Maximum Daily Load (TMDL) studies and Watershed Restoration and Protection Strategy (WRAPS) reports.
The goal of this project is to develop forestry related best management practice (BMP) pollutant reduction/management efficiencies, costs, and management information applicable to Minnesota forests and incorporate these BMPs into the Hydrological Simulation Program FORTRAN (HSPF) model Scenario Application Manager (SAM) tool. By incorporating forestry BMPs into the existing SAM tool, forestry related management scenarios can be evaluated for potential impacts on surface waters and can inform the development of watershed restoration and protection strategies.
The goal of this work order is to collect and process the watershed specific files needed to create the Scenario Application Manager (SAM) project files to apply the SAM software in selected major watersheds in Minnesota where an Hydrological Simulation Program – FORTRAN (HSPF) model has been developed. This work order will also involve technical support for the SAM users who are applying the SAM projects.
The primary goal of this project is to examine the calibration and validation of recently extended Hydrological Simulation Program – FORTRAN (HSPF) watershed models for the Mississippi River-Headwaters, Mississippi River-Grand Rapids, Mississippi River-Brainerd, Mississippi River-Sartell, Mississippi River-St. Cloud, Leech Lake, Pine River, Crow Wing River, Long Prairie River, and Redeye River watersheds and revise the calibration.
The goal of this project is to develop guidance for water quality parameter evaluation and calibration for Hydrological Simulation Program FORTRAN (HSPF) applications focused on dissolved oxygen (D.O.), nutrient, and algal simulation, along with a demonstration of the guidance by step-by-step application to D.O.-impaired Minnesota watersheds.
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.
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.
