Hydrologic Information and Data for Colorado

The U.S. Geological Survey currently operates over 200 data collection sites in Colorado for acquiring information on surface-water, groundwater, water-quality, and precipitation. Many of the sites are equipped with satellite telemetry, which provides real-time data via GOES satellites and downlinks, which enables the posting of data to the Web for public dissemination.
