Data

This data release contains output from a numerical snow simulation for a 166 kilometer (km) × 160 km model domain in the Qashqadaryo region of Uzbekistan. The simulation encompasses key watersheds within the region and uses SnowModel (Liston and Elder, 2006; Liston and others, 2020; Liston, 2020) to estimate the snow water resources and meteorology across the simulation domain. The...

Water was sampled in streams from Butte to near Missoula, Montana, as part of a long-term monitoring program in the upper Clark Fork Basin. The sampling program was completed by the U.S. Geological Survey (USGS), in cooperation with the U.S. Environmental Protection Agency, to characterize aquatic resources in the upper Clark Fork Basin and monitor trace elements associated with...

This data release contains historical and future climate SnowModel (Liston and Elder, 2006; Liston and others, 2020; Liston, 2020) simulation outputs on a 100-meter (m) geospatial grid for a 392-kilometer (km) x 469-km model domain in the Upper Colorado River Basin. The historical simulation (control, CTL) was run from 1979-09-01 to 2022-08-31 using the CONUS404 meteorology dataset...

Water, bed sediment, and invertebrate tissue were sampled in streams from Butte to near Missoula, Montana, as part of a long-term monitoring program in the upper Clark Fork Basin. The sampling program was completed by the U.S. Geological Survey (USGS), in cooperation with the U.S. Environmental Protection Agency, to characterize aquatic resources in the upper Clark Fork Basin and monitor...

The Wyoming-Montana Water Science Center, in cooperation with the Wyoming Department of Environmental Quality, digitized layers to determine the backwater extent behind Willwood Dam on the Shoshone River near Cody, Wyoming from 2012, 2015, 2017, 2019, and 2022 National Agriculture Imagery Program (NAIP) imagery. Digitizing layers of water extents behind Willwood Dam through time allows...

We applied machine learning (ML) models to forecast streamflow drought from 1 to 13 weeks into the future at more than 3,000 streamgage locations across the Conterminous United States. We applied two machine learning methods (long short-term memory [LSTM] neural network; light gradient boosting [LightGBM] machine) and two benchmark model approaches (persistence; autoregressive integrated...

The U.S. Geological Survey (USGS), in cooperation with the Wyoming Water Development Office, delineated watersheds for 800 active and discontinued USGS streamgages in and near Wyoming. This data release includes shapefiles of streamgage location points and polygons of their delineated watersheds. Streamgage locations were snapped to the USGS High Resolution National Hydrography Dataset...

The Wyoming-Montana Water Science Center collected continuous gage height data at 30-second intervals at Yellowstone River at Yellowstone Lake Outlet, Yellowstone National Park (YNP), U.S. Geological Survey (USGS) streamgage 06186500, from 2011–2023 in a partnership with the USGS Volcanic Science Center. River gage height data can indicate changes in seismic activity at this location...

The U.S. Geological Survey (USGS) Wyoming-Montana Water Science Center (WY-MT WSC), in collaboration with the USGS Northern Rocky Mountain Science Center (NOROCK), measured streamflow in three headwaters basins in Wyoming and Montana to better quantify streamflow, particularly during lower flows in the late summer and fall. The WY-MT WSC installed two streamgages in each of the three...

The Central Asia Equal Area Projection and Model Grid (CAEAP-MG) dataset includes raster and vector representations of 1-km cells defining a uniform equal-area grid encompassing the Republics of Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan. The grid is extended south into Afghanistan for purposes of encompassing the northward drainages into Central Asia including the...

The U.S. Geological Survey (USGS), in cooperation with the Montana Department of Transportation (MDT), collected water-surface profile data at selected highway bridges in Montana. The water-surface profile data characterizes the water-surface elevation and slope upstream and downstream of a bridge. Water-surface profile data were typically obtained for one side of the stream by surveying...

The U.S. Geological Survey (USGS), in cooperation with the Montana Department of Transportation (MDT), collected various data at selected bridges in Montana. The data collected in the field included streambed cross-section data, longitudinal streambed profile data, and water-surface profile data. Efforts included overlaying pier structure geometry on the plots to demonstrate the position...
