Additional Resources
RecommendedRealtime, recent, and forecasted hydrologic data with tools and forecasts for the Colorado River Basin.
A diverse set of climate viewing tools available though one portal, the climate toolbox offers many ways to analyze and view past data and future projections
Provisional natural flow of the Colorado River at Lees Ferry, AZ.
A web-based clearinghouse for scientific and technical information relevant to the Colorado River Basin and the management of its water resources and related natural resources. The Clearinghouse is intended to be useful to managers and other decision-makers, to researchers, to the media, and to the broader public.
Interactive map viewer showing daily snow coverage across the Western United States that allows users to explore variables like total snow cover, snow water equivalent (SWE), albedo, and radiative forcing. Summary data can be produced for States, Regions, and HUC basins. Check out the snow-viewer guide here: Snow viewer guide.
Dashboard showing the status of surface water and surface water storage in the upper Colorado River Basin.
NRCS Interactive Map customized to show the adjusted streamflow for the current water-year-to-date, as a % of the period-of-record average. Click on a gage of interest to bring up a popup, click on the popup to expand it, and then click on Data Reports and either Water Year Table or Water Year Chart for the current year’s monthly flows. For historical flows at that gage, open the Water Year Table, click on the Create/Modify Report tab in the upper left. When the tab opens, click the first checkbox for ‘stream volume, adjusted’ then below that, change Time Period to “Period of Record”, then click on the View Report tab at upper left.
Interactive map viewer of all the hydrological monitoring sites run by the U.S. Geological Survey in the Colorado River Basin.
OpenET uses the best available science to provide easily accessible satellite-based estimates of evapotranspiration (ET) for improved water management across the western United States.
A guided exploration of the Colorado River providing context about many of the most pressing land and water issues in the basin.
