Data Releases

The swath laser was tested at the large-scale experimental USGS debris flow flume facility as a potential tool for mass movement detection. The tests were conducted during gate release experiments, where a large volume of sediment was released from a hopper; and during natural release experiments, where a sediment prism was watered until wide-spread Coulomb failure occurred. During the...

A three-dimensional unsaturated-zone flow model was developed using Hydrus-3D (PC-Progress, Inc.) to simulate managed aquifer recharge at the Southeast Houghton Artificial Recharge Project (SHARP) in Tucson, AZ. Recharge, up to about 4,000 acre-feet per year, takes place at three surface basins. The model simulates variable-saturated flow in the unsaturated zone and groundwater mounding...

This GIS dataset presents contours and maps from previously published interpretations of hydrogeologic units of the northern Great Plains by Downey (1986). The original source publication was completed as a component of the United States Geological Survey’s (USGS) Regional Aquifer System Analysis (RASA) professional paper series. Isopach contour maps in this study delineate the upper...

This dataset includes water-quality data collected at 16 sites in the Clear Lake Drainage Basin, Lake County, California, between November 2018 and March 2025. Sampling targeted high-flow events following rainfall and baseline conditions during the wet season (typically December through April) across multiple water years (WYs), with expanded coverage in WYs 2022–2024 and new data added...

This dataset provides groundwater age estimates for 175 wells used as domestic supply in four selected areas of California. Groundwater ages were estimated by calibration of environmental tracers (tritium, tritiogenic helium-3, sulfur hexafluoride, carbon-14 and radiogenic helium-4) to lumped parameter models (LPMs). Calibrated lumped parameter models provide the optimal mean age and...

This data release includes text files of well data and shapefiles of potentiometric contours of the Fort Union, Hell Creek, and Fox Hills aquifers within the Standing Rock Reservation. The data accompanies a USGS scientific investigations map from Anderson and Lundgren (2024). The Standing Rock Sioux Tribe (the Tribe) of North and South Dakota and the U.S. Geological Survey (USGS)...

This data release contains peak-flow frequency analyses for selected streamgages in Lincoln County, Montana, along with information documenting the input data and specifications for the analyses. The analyses were performed using the methods described by Siefken and others (2025).

These datasets support the conclusions in the journal article entitled "Population vulnerability of residents, employees, and cruise-ship passengers to tsunami hazards in complex seismic regions: a case study of the U.S. Virgin Islands" as described in the abstract below: Reducing the potential for loss of life from tsunamis is challenging on islands located in complex seismic regions...

This data set describes the genomic bacterial analysis of swabs and tissues collected from whooping cranes in Louisiana. The data includes targeted analysis from quantitative PCR for bacterial pathogens.

Caves preserve useful archives of fluvial sediments, especially in mountainous landscapes that hinder the preservation of thick, dateable terrace deposits. We used cosmogenic ²⁶Al and ¹⁰Be to date the burial of sediments in four caves along tributaries of the New River: Windy Mouth Cave along the Greenbrier River in West Virginia, Haynes Cave along Second Creek in West Virginia, Bone...
