Some days are so clear it seems you can touch the mountains! Setting up a new streamgage on the Gros Ventre River above Upper Slide Lake, October 18, 2017.

Many rivers require cableways to measure high flows. Recently our streamgagers learned how to inspect the cableway and ensure that it is safe (Yellowstone River at Billings, Montana, March 9, 2018).

Hydrologic Information and Data for Wyoming and Montana

The U.S. Geological Survey currently operates hundreds of data collection sites in Montana and Wyoming for acquiring information on surface-water, groundwater, water-quality, and precipitation. Many of these 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.
