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 Metropolitan Council was awarded $1,250,000 from Minnesota Clean Water, Land and Legacy Amendment funds for a Water Efficiency Grant Program during the Minnesota Legislature's 2021 First Special Session. The Metropolitan Council (Council) implemented a water efficiency grant program effective July 1, 2022 to June 30, 2024. Grants were awarded on a competitive basis to municipalities that are served by a municipal water system. The Council provides 80% of the program cost; the municipality must provide the remaining 20%.
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.
This program supports communities as they plan and implement projects that address emerging drinking water supply threats. It supports the exploration cost-effective regional and sub-regional solutions, leverages inter-jurisdictional coordination, and prevents overuse and degradation of groundwater resources.
The Watershed Health Assessment Framework (WHAF) is a web-based tool for resource managers and others interested in the ecological health of Minnesota's watersheds. The framework uses five ecological components to organize and deliver information about watershed health conditions in Minnesota. The five components are hydrology, connectivity, biology, geomorphology, and water quality. Statewide GIS data from DNR and partner agencies are used to calculate health scores that reveal similarities and differences between watersheds.
The DNR provides technical support related to the causes of altered hydrology and watershed management solutions. We use state-of-the-art models and statistical methods to look at cumulative impacts of drainage and land-use practices and determine the benefits of best management practices. This involves collaboration with multiple partners 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.
DNR regional clean water specialists and area hydrologists work with regional staff from other state agencies and with local partners to help identify the causes of pollution problems and determine the best strategies for fixing them. We collect and analyze stream channel stability and streambank erosion data to help identify root causes of certain water quality impairments in streams.
The goal of this project is to maintain and make enhancements to the Winter Maintenance Assessment tool (WMAt), which is a necessary technical resource and planning tool for stakeholders and permittees to implement the chloride reduction strategies described in the Chloride Management Plan. The WMAt is critical for assisting stakeholders in meeting the water quality goals of the Chloride Management Plan without compromising public safety, and allowing for consideration of the varying resources and conditions for each individual winter maintenance program.
