USGS: Summer Runoff Does Little to Ease Drought U.S. Geological Survey (USGS) preliminary streamflow data show eight streamflow stations across Wyoming set new record lows for total annual runoff during the past water year. Total annual runoff is the volume of water that flows past the streamflow-gaging station in a years time. "The total runoff for the last year ranged from less than 25 percent of average in the southeastern part of Wyoming to near average in the northwestern part of the state," noted Myron Brooks, USGS Hydrologist. "Five of the stations setting record lows are located along the North Platte River in the southeastern part of the State," noted Brooks, "two are in the Big Horn Basin in central Wyoming, and one in the Green River Basin in southwestern Wyoming." The upper parts of the Yellowstone and Wind River Basins in northwestern Wyoming faired better, where runoff at streamflow-gaging stations in those areas ranged from about 60 percent of average to near average. Recent photographs of streams in Wyoming along with other information about drought conditions in the State are available at the U.S. Geological Survey’s (USGS) Wyoming Drought Watch.

1895, the USGS has collected streamflow data, often
in cooperation with other agencies, at more than 2,000 sites
throughout Wyoming. About 150 streamflow data collection stations
currently are in operation. Additional information, including current
streamflow conditions in Wyoming, can be found by accessing the Water
