Data

This data release was produced by the U.S. Geological Survey (USGS) in cooperation with the Bureau of Reclamation (Reclamation) to present the results of monitoring efforts on the Yellowstone River fish bypass channel according to the specifications of the Lower Yellowstone Adaptive Management and Monitoring Plan. The fish bypass channel was constructed to provide upstream migrating fish...

The U.S. Geological Survey (USGS), in cooperation with the Wyoming Water Development Office (WWDO), developed streamflow statistics regression equations using basin characteristics and streamflow statistics at streamgages for mean daily discharge data through water year 2021. This data release provides supplementary data to the Scientific Investigation Report (SIR), "Methods for...

This model archive summary (MAS) and associated model calibration dataset documents the suspended-sediment concentration (SSC) model developed to compute 15-minute, near-real-time SSC at U.S. Geological Survey (USGS) streamgage station 06329500, Yellowstone River near Sidney, Montana (MT) for calendar years 2022-2024 and is the model currently in use. This model is specific to USGS site...

This model archive summary (MAS) and associated model calibration dataset documents the suspended-sediment concentration (SSC) model developed to compute 15-minute, near-real-time SSC at U.S. Geological Survey (USGS) streamgage station 06329500, Yellowstone River near Sidney, Montana (MT) for calendar years 2017-2021. This model is specific to USGS site 06329500, Yellowstone River near...

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...
