Data Releases

The 3DEP U.S. Geological Survey (USGS) Inland Bathymetric and Topobathymetric Survey Inventory for the conterminous US is a database for digital, geospatial three-dimensional bathymetric and topobathymetric datasets created as a resource for public and private science and engineering analyses and modeling. Initiated in 2018, the database includes all published USGS inland to coastal survey reports

Green Peter Dam on the Middle Santiam River and the downstream Foster Dam on the South Santiam River in Oregon have altered natural seasonal temperature patterns in those rivers. In response, the U.S. Army Corps of Engineers is leading efforts to improve conditions for Chinook salmon upstream and downstream of these dams by considering structural alterations and by exploring changes to the way the

U.S. Geological Survey (USGS) scientists conducted field data collection efforts during the week of September 25 - 29, 2017, using a combination of conventional surveying technologies, for a large stretch of the Kootenai River near Bonners Ferry, Idaho. The work was initiated as an effort to validate commercially acquired topobathymetric light detection and ranging (lidar) data. The goal was to co

The U.S. Geological Survey (USGS) developed models to estimate plant-level thermoelectric water use based on linked heat-and-water budgets to provide a consistent method for water-use estimation across the fleet of U.S. thermoelectric plants. In addition to calculating a thermodynamic “best” estimate for each powerplant, the models also calculate plausible ranges of minimum and maximum withdrawal

Data included in this data set are for an experiment conducted in 2018. Data were collected on survival, growth, food consumption, and Ichthyobodo copy numbers of Lost River suckers exposed to five different temperature groups. There are five levels of data. Temperature data contains 1,178 records and the data file is 35 KB, survival data contains 150 records and the data file is 3 KB, food consum

The Consortium of Organizations for Strong Motion Observation Systems (COSMOS) supported blind trials using passive microtremor array data for shear-wave velocity site characterization. The trials included data from four sites in order to consider limitations imposed by differing geologies, differing sparse array geometries, and differing interpretation methodologies. The trials used a four-phase

This U.S. Geological Survey (USGS) data release provides the descriptions of 11 U.S. sites that include mineral regions, mines, and mineral occurrences that contain enrichments of niobium (Nb). To be included in this data release, a site must have a contained resource and (or) past production of Nb metal greater than 10,000 metric tons, which was the approximate consumption of Nb in the U.S. in 20

A series of linear regression models were developed and calibrated for two Lower Minnesota River sites. The linear regression models were either calibrated using acoustic or streamflow data to estimate suspended-sediment or sand concentration data. Data were collected during calendar years 2012 through 2019. The estimates of suspended-sediment and concentrations from the linear regression were use

Contents include U.S. Geological Survey (USGS) flood-frequency analysis software PeakFQ input files (.psf specification file and peak-flow data file) and output files (.prt file of flood-frequency results) for selected streamgaging stations near Jefferson County, Missouri. Ten stations are included with flood-frequency results updated from Southard and Veilleux (2014) and peak-flow record through

Asian swamp eel, Monopterus albus/javanensis [Zuiew, 1973/Lacepede, 1800], has been established in the southeastern USA since at least 1994, yet little is known about its ability to survive low winter temperatures. We use standard thermal methodologies to quantify low-temperature responses and provide a detailed description of swamp eel reactions to cold temperatures. When exposed to chronic tempe

Restoration of the Florida Everglades, a substantial wetland ecosystem within the United States, is one of the largest ongoing restoration projects in the world. Decision-makers and managers within the Everglades ecosystem rely on ecological models forecasting indicator wildlife response to changes in the management of water flows within the system. One such indicator of ecosystem health, the pres

The data contained in these tables detail the areal extent of exposed sand, in square meters, along the Colorado River between Glen Canyon Dam, Arizona, and Bright Angel Creek, Arizona, within Glen Canyon National Recreation Area and Grand Canyon National Park. Sand exposure areas are provided as a function of Colorado River discharge, as measured at Lees Ferry, Arizona, in increments of 1000 cubi
