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...

The U.S. Geological Survey (USGS), in cooperation with the Montana Department of Transportation (MDT), collected longitudinal streambed profile data along the sides of piers at selected bridges in Montana. The streambed profile data extends upstream and downstream of piers so that local pier scour effects might be distinguished from more general geomorphic scour processes. Two or more...

The U.S. Geological Survey (USGS), in cooperation with the Montana Department of Transportation (MDT), collected channel cross-section geometry data on the upstream and downstream sides of selected highway bridges in Montana. The cross-section data typically extend the full width of the streambed at the bridge opening and up the abutments so that local pier scour effects and more general

This data release contains water temperature and specific conductance data from Lake Koocanusa at the international boundary (USGS site number 12300110) from November 2024 to April 2025. Data were collected every 30 minutes at depths of 3 meters (m) and 10 m below the water surface. These data were collected as part of a water-quality monitoring program in Lake Koocanusa to provide data...

The land application of drill fluids is governed by rules established in the Oklahoma Administrative Rules (165:10-7) and permitted by the Oklahoma Corporation Commission (OCC). While data on the volume and location of land application is publicly accessible through the OCC's website, much of the information is in scanned form documents which limits the operability of these data. This...

The USGS Wyoming-Montana Water Science Center (WY–MT WSC) completed a report (Siefken and others, 2025) documenting methods for peak-flow frequency analysis following implementation of the Bulletin 17C guidelines. This data release, published in cooperation with the Wyoming Water Development Office, presents peak-flow frequency analyses for selected streamgages in Wyoming, based on data...
