- Interactive Dashboard
This Interactive Dashboard provides access to visualizations for a variety of geographic information system datasets. By visualizing this data, both researchers and the public may analyze and collaborate on a variety water management issues (and their solutions), which affect the Western United States.
The American West faces serious water challenges. Widespread drought, increasing populations, aging infrastructure, and environmental requirements, which collectively, strain existing water and hydropower resources.
Adequate and safe water supplies are fundamental to the health, economy, and security of the country. Through WaterSMART (Sustain and Manage America’s Resources for Tomorrow), Reclamation continues to work cooperatively with states, tribes, and local entities as they plan for and implement actions to increase water supply through investments to modernize existing infrastructure and attention to local water conflicts.
Reclamation published an updated SECURE Water Act Report to Congress. The report highlights findings from basin-specific collaborative planning studies that provide a West-wide perspective on anticipated impacts to water resources due to climate change and corresponding adaptation strategies.
Reclamation collaborated with the Desert Research Institute and the University of Idaho in the development of a state-of-the-science computerized evapotranspiration (ET) model (ET Demands) that is being used to estimate historical and future agricultural irrigation water demands for the Western United States.
Reclamation published an Irrigation Demand and Reservoir Evaporation Projections report as a Baseline Water Assessment activity under the WaterSMART Basin Study Program in 2015. The technical memorandum report provides an analysis of future changes in irrigation water demand across Reclamation’s major river basins (Colorado, Columbia, Klamath, Missouri, Rio Grande, Sacramento/San Joaquin and Truckee/Carson). The technical assessment report provides an analysis of future changes in irrigation water demand across Reclamation’s major river basins (Colorado, Columbia, Klamath, Missouri, Rio Grande, Sacramento/San Joaquin and Truckee/Carson).
Streamflow projections are being made available to provide immediate access for the convenience of interested persons. Data files for monthly and daily projected streamflows can be downloaded from the web application Climate-Adjusted Streamflow Projections for Western US.
The U.S. Department of Interior's Bureau of Reclamation, the University of Washington's Climate Impacts Group (CIG), and the National Oceanic and Atmospheric Administration (NOAA) National Weather Service (NWS) Colorado Basin River Forecast Center, (ie, Archive Collaborators) believe the information to be correct representations of potential high-resolution climate/hydrologic variations and changes subject to the limitations of the CMIP3 global climate simulations, and the downscaling methods and their limitations, as described at the Bias Corrected and Downscaled Climate and Hydrology Projections website.
Every five years, Reclamation submits a report to Congress under the SECURE Water Act analyzing projected risks to water supplies in the West using the best available science and highlighting collaborative efforts to mitigate those risks. The Water Reliability in the West – 2021 SECURE Water Act Report (2021 Report) provides a West-wide assessment of changes to water supplies, uses, and demands and highlights progress and describes actions taken to increase water supply reliability since the 2016 Report. The 2021 Report summarizes the more detailed information in the West-Wide Climate and Hydrology Assessment (2021 Assessment) and the SECURE Water Act Basin Reports and factsheets in conjunction with the SECURE Report.
