In 2016, the U.S. Geological Survey (USGS) in partnership with IDWR embarked on a five-year project to construct a numerical groundwater-flow model of the Treasure Valley and surrounding area. Resource managers will use the model for water-supply planning and management. As part of model construction, the hydrogeologic understanding of the aquifer system will be updated with information collected during the last two decades as well as new data collected for the study. Funding for the project is being provided by the USGS and by the Idaho Water Resource Board through a special appropriation from the Idaho Legislature for statewide aquifer stabilization and sustainability studies (see Senate Concurrent Resolution 137). A technical advisory committee provides for transparency in model development and facilitates stakeholder input. Additional information describing the collaborative USGS-IDWR Treasure Valley groundwater-flow model development project is provided in the project summary.
TVGWFM Data Release The USGS has published the Treasure Valley Groundwater Flow Model in a January 2023 data release. You can access the completed model files on the USGS's website.
