In the moist, coniferous forests of Oregon and Washington, a dense network of headwater streams supports high levels of amphibian species endemism and diversity, including the torrent salamanders (Rhyacotriton spp.). The Columbia and Cascade torrent salamanders (R. kezeri and R. cascadae, respectively) are species of greatest conservation need, but current information is insufficient for...

This data release contains frequency domain electromagnetic (FDEM) and passive seismic horizontal to vertical spectral ratio (HVSR) geophysical data collected over and in the vicinity of the Dolores River in Paradox Valley, Colorado. The data collection area is comprised of an approximate 7-kilometer reach of the river and surrounding 100-meter buffer zone on both banks. Water depth and...

We conducted an infection experiment to evaluate how little brown bats from two distinct hibernacula in Michigan responded to a standardized exposure to the causative agent of white-nose syndrome. The dataset includes individual bat survival, body weight measurements, infection load assessments, and histological analyses. Additionally, we collected in situ infection load data from bats...

This dataset includes sediment temperature data collected from seven sites on the mainstem of the Quillayute River in the summer of 2024. Sediment temperatures were collected at up to four depths (1, 4, 7, and 11 centimeters) at each location using a temperature rod that was installed into the streambed. See "quillayute.sites.2024.csv" for field IDs, sediment thermal properties, and...

This data release contains the concentration and quality assurance results for 30 streams, sampled twice. In 2023, the typology sampled was Pennsylvania and Maryland Piedmont mixed agriculture. Each dataset consisted of 30 sampling sites. Samples were analyzed for the following constituent classes (count of constituents); field and water-quality parameters (9), nutrients/anions (13)...

This data release contains spatially and temporally aggregated data from a particular application of the Weather Research and Forecasting hydrological model (WRF-Hydro; Gochis and others, 2025) from water year 1980 through 2022 for the conterminous United States (Rafieeinasab and others, 2026). This modeling application is climatologically forced with a modified version of the CONUS404...

The U.S. Geological Survey, in cooperation with the City of Summerset, South Dakota, performed electrical resistivity tomography (ERT) surveys between July 28 and August 5, 2025. ERT data were collected using an Advanced Geosciences Incorporated SuperSting with 2 passive cables with 14 electrodes per cable. In total, ERT data were collected along 13 transects using 2 passive cables and...

This data release contains predictions of stream biological condition as defined by the Chesapeake basin-wide index of biotic integrity for stream macroinvertebrates (Chessie BIBI) as well as prediction of the percentage of the benthic macroinvertebrate assemblage as 1) Ephemeroptera, Plecoptera, Trichoptera less Hydropsychidae, 2) Ephemeroptera, and 3) Clingers using Random Forest...

Reservoir outflows and downstream water temperatures in the Willamette River Basin, Oregon, are influenced by the operation of 13 U.S. Army Corps of Engineer (USACE) dams that comprise the Willamette Valley System (WVS). CE-QUAL-W2 models have been developed to simulate water release temperatures from a subset of WVS dams, and thermal effects to downstream reaches that may result from...

This dataset contains results of weighted least-squares (WLS) regression for 42 streamflow gaging stations (streamgages) operated by the U.S. Geological Survey (USGS) on urban streams in Alabama and Mississippi. WLS regression was used to relate drainage area and the percentages of the drainage basins of the streamgages in developed land use (the sum of classes 21-24 from the 2011...

In the western United States, there has been a long history of planting fish into historically fishless mountain lakes for the purpose of recreational fishing. This practice can have detrimental effects to lake ecosystems, particularly amphibian populations. We compiled records of fish plantings into lakes on the Olympic Peninsula in western Washington State dating back to 1930. Our...

In 2001, the Alaska Division of Geological & Geophysical Surveys (DGGS) published a database compiling geotechnical borehole and well-log records in Anchorage, Alaska (Combellick and others, 2001). This data release builds on that database, adding some additional cone penetration test (CPT) and well log records in broader areas across the state (Alaska Department of Natural Resources...
