Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Kootenai River Topobathymetric Lidar Validation Survey Data Kootenai River Topobathymetric Lidar Validation Survey Data
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...
Water withdrawal and consumption estimates for thermoelectric power plants in the United States, 2015 (ver. 1.2, July 2024) Water withdrawal and consumption estimates for thermoelectric power plants in the United States, 2015 (ver. 1.2, July 2024)
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...
Data from 2018 Experiment on Effects of Temperature on Survival and Growth of Juvenile Lost River Suckers (Deltistes luxatus) naturally exposed to Ichthyobodo spp Data from 2018 Experiment on Effects of Temperature on Survival and Growth of Juvenile Lost River Suckers (Deltistes luxatus) naturally exposed to Ichthyobodo spp
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...
Data release for: An assessment of uncertainties attributed by analysts, array types and processing algorithms for microtremor observations, using the phased 2018 COSMOS Blind Trials Data release for: An assessment of uncertainties attributed by analysts, array types and processing algorithms for microtremor observations, using the phased 2018 COSMOS Blind Trials
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...
Niobium Deposits in the United States Niobium Deposits in the United States
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...
Suspended-sediment and sand concentrations, streamflow, acoustic data, linear regression models, and loads for the Lower Minnesota River, 2012-2019 Suspended-sediment and sand concentrations, streamflow, acoustic data, linear regression models, and loads for the Lower Minnesota River, 2012-2019
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...
PeakFQ software input files and selected output files for selected long-term streamgages near Jefferson County, Missouri, through water year 2019 PeakFQ software input files and selected output files for selected long-term streamgages near Jefferson County, Missouri, through water year 2019
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...
Non-native Asian swamp eel, Monopterus albus/javanensis (Zuiew, 1973/Lacepede, 1800), responses to low temperatures Non-native Asian swamp eel, Monopterus albus/javanensis (Zuiew, 1973/Lacepede, 1800), responses to low temperatures
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...
EverWaders species distribution model development and output in the Greater Everglades from 2000-2009 EverWaders species distribution model development and output in the Greater Everglades from 2000-2009
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...
Discharge records and sand extents along the Colorado River between Glen Canyon Dam and Phantom Ranch, Arizona Discharge records and sand extents along the Colorado River between Glen Canyon Dam and Phantom Ranch, Arizona
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...
Stream classification and gravel bar inventory for Buffalo National River and Ozark National Scenic Riverways, 1982-2014 Stream classification and gravel bar inventory for Buffalo National River and Ozark National Scenic Riverways, 1982-2014
This data release contains numerous shapefiles that describe baseline characterization of the physical attributes of the riverine ecosystems in two national parks - Ozark National Scenic Riverways (ONSR), Missouri, and Buffalo National River (BNR), Arkansas. The individual metadata associated with each shapefile describe in detail the specific process steps, source inputs for the data...
