Beaver dams can help streams connect to their floodplains. These floodplain connections can expand the range of available aquatic habitats and aid in the restoration of stream and floodplain processes. North American beavers (Castor canadensis) occupy a wide variety of aquatic habitats; however, their ability to build dams, the agent of stream and floodplain change, is constrained in...

Stream-like habitats in abandoned mine areas of New River Gorge National Park and Preserve were surveyed for stream salamanders in fall 2024. Methods included visual encounter surveys of transects up to 25m within stream-like mine water discharges in the Nuttallburg, Fayette Station, Hawks Nest Connector, and New River Gorge Bridge areas of the park. All stream salamander species...

This Data Release provides stream temperature data (13 sites) and fish community data (3 sites) in Big Hunting Creek, Maryland. Data were collected during summer baseflow conditions in 2023. This product supports brook trout conservation and restoration research needs identified by Maryland Department of Natural Resources. We collected temperature data with Onset ProV2 water temperature...

Warming climates, declining winter snowpacks, and increased periods of drought have contributed to warming stream temperatures and declining stream flows, impacting habitat availability for cold water species. Particularly in the northern Great Basin region available habitat may be restricted to headwaters, where cooler temperatures and reliable stream flows allow cold water species...

Stream Temperature, Intermittency, and Conductivity (STIC) loggers were deployed in tributaries of the Colorado River, TX to monitor for water presence. These loggers were deployed in a riffle and pool mesohabitat at 19 sites and recorded a measurement every six hours from June 2022 to March 2024. The loggers record temperature and relative conductivity. We calculated drying metrics...

Groundwater is often supersaturated in greenhouse gases (GHGs; i.e. CO2, CH4, N2O) and delivers these gasses to stream channels where they are either emitted, consumed, or transported downstream. However, areas of relatively spatially-focused (‘preferential’) groundwater discharge may also be located above the waterline and be immediate sources of GHGs to the atmosphere before moving...

This data release contains streambed sediment data, suspended sediment data, and stream stage data from tributary streams in Western Montana. These datasets were created to assess the linkages between unpaved roads and instream sediment distributions. Surveys were collected in tributaries and rivers within the Clearwater River and Swan River basins in Montana. Site locations were...

In cooperation with the West Virginia Division of Transportation, Department of Highways (WVDOH), precipitation and streamflow were measured at four streamgages in West Virginia to compute time of concentration (Tc) and compare it to Tc estimates made using accepted methods. Precipitation and streamflow data were collected during 2017-2020. Storms were identified and classified through...

Stream temperature data and streamflow data from headwater streams in the upper Snake River basin, Wyoming and upper Yellowstone River basin and Flathead River basin in Montana. These datasets were assembled to assess how stream temperature and streamflow in headwater streams deviates from downstream gages in order to better understand tools to estimate streamflow at a variety of...

This data release presents streamflow recession analyses and supporting statistics for 164 U.S. Geological Survey (USGS) streamgages located in or near the watersheds of Mobile and Perdido Bays in the south-central United States (see Tatum and others, 2024). Streamgages were selected based on a minimum of two complete decades of daily streamflow data since January 1, 1950, with the...

The U.S. Geological Survey (USGS), in cooperation with the Nez Perce Tribe, used streamflow measurements at 12 ungaged, partial-record sites and developed relationships with nearby USGS real-time streamgages (index sites) to provide daily mean streamflow values at partial-record sites in the Clearwater River basin. Daily mean streamflow was estimated by developing a regression...

The U.S. Geological Survey (USGS), in cooperation with the Wyoming Water Development Office, developed streamflow statistics for active (through September 30, 2021) and discontinued USGS streamgages in and near Wyoming with 10 or more years of daily mean streamflow record. Streamflow at each streamgage was assessed for degree of human alteration owing to dams and diversions before...
