Data from 391 boreholes (including coreholes) that penetrated buried pre-Cretaceous basement rocks that lie beneath Atlantic Coastal Plain sedimentary deposits in Georgia and South Carolina were compiled from non-proprietary, mostly published sources in order to support subsurface geologic mapping, geologic interpretation of geophysical data (aeromagnetic, gravity, seismic), topical studies as in geochronology, and applications ranging from mineral, energy, and water resources to earthquake hazards in the Charleston seismic zone. Most of the entries are based on previous literature. In a few cases where noted, drill cores or cuttings were examined for basic geologic observations. Boreholes into bedrock beneath the...

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, and the specific river the data characterize.
The U.S. Geological Survey National Water Information System (NWIS) data archive contains publicly available water-quality data for approximately 20,000 groundwater wells and springs in California. This data release publishes site type information and a generalized use classification for the sites. The generalized use category is derived from, but is not equivalent to, the use of site and use of water fields from the NWIS data archive. The use of site and use of water fields in the NWIS data archive are not publicly available. The 20,000 groundwater wells and springs were categorized as into seven generalized use categories: 1) domestic, 2) irrigation, 3) production, 4) water supply, other, 5) observation, 6) other,...

This data release consists of four network Common Data Form (netCDF) files of bias-corrected daily precipitation at 1-kilometer (km) scale for historical and projected climate of Puerto Rico. The Weather Research and Forecasting (WRF) model was used by Bowden and others (2018) to downscale two general circulation models (GCMs) from the Coupled Model Intercomparison Project phase 5 (CMIP5): (1) the Community Climate System Model (CCSM4 or CESM), and (2) the Centre National de Recherches Meteorologiques-CERFACS (CNRM). The two models were dynamically downscaled using WRF for a historical (1985-2005) time slice and a future time slice (2040–60) under the high greenhouse gas emission scenario known as Representative...

This dataset includes streamflow measurements collected at six sites in Pinnacles National Park during 2018. Data collection occurred at times when the streamflow did not include runoff from precipitation. The wading method was used to measure streamflow (Nolan, K.M. and Shields, R.R., 2000, Measurement of stream discharge by wading, U.S. Geological Survey Water-Resources Investigations Report 2000-4036, 106 p.). By this method, the stream channel cross section is divided into subsections. For each subsection, a tape measure is used to measure the distance from the left stream bank (as facing downstream), a wading rod is used to measure the channel depth, and a velocity meter attached to the wading rod is used to...

U.S. Army Corps of Engineers river stage and discharge data (www.rivergages.com) were used to calculate longitudinal connectivity, which is represented by the number of days each lock and dam is in “open river” conditions. During high water conditions, dam gates are generally lifted out of the water or lowered to the river bottom, removing physical barriers to passage (“open river condition”). Each lock and dam in the Upper Impounded and Lower Impounded Reaches has a specific discharge or stage that when reached, results in open river conditions. For each lock and dam, we calculated the average annual number of days in which daily discharge or stage would have resulted in open river conditions between 1985 and 2015....
This data release contains trend results computed on the basis of modeled and observed daily streamflows at 1,257 gages across the conterminous U.S. from October 1, 1983 through September 30, 2016. Study gages were selected from the GAGES-II dataset of gages classified as non-reference which means streamflows may be affected by human influence. Modeled daily streamflows were computed using the deterministic Precipitation Runoff Modeling System (PRMS), and five statistical techniques: Nearest-Neighbor Drainage Area Ratio (NNDAR), Map-Correlation Drainage Area Ratio (MCDAR), Ordinary Kriging of the logarithms of discharge per unit area (OKDAR), Nearest-Neighbor nonlinear spatial interpolation using flow duration curves...

This data release includes information used to support interpretations of relations between precipitation and soil moisture for a U.S. Geological Survey post-fire monitoring array installed near Malibu, CA following the 2007 Canyon fire. The 3 datasets are: 1) a time series of precipitation from three tipping bucket rain gages in individual files (Schmidt_2020_CANVQRG1.csv, Schmidt_2020_CANVQRG2.csv, and Schmidt_2020_CANTPRG3.csv; where RG in file name is abbreviation for rain gage), 2) a time series of a total of 9 soil moisture probes distributed with three soil moisture probes installed at varying depths from 3 individual soil pits in 3 individual files grouped by pit (Schmidt_2020_CANVQSM1.csv, Schmidt_2020_CANVQSM2.csv,...
This data release consists of Microsoft Excel workbooks, shapefiles, and a figure (png format) related to a cooperative project between the U.S. Geological Survey (USGS) and the South Florida Water Management District (SFWMD) to derive projected future change factors for precipitation depth-duration-frequency (DDF) curves at 174 National Oceanic and Atmospheric Administration (NOAA) Atlas 14 stations in central and south Florida. The change factors were computed as the ratio of projected future (2050-2089) to historical (1966-2005) extreme precipitation depths fitted to extreme precipitation data using a constrained maximum likelihood (CML) approach. The change factors are tabulated by duration (1, 3, and 7 days)...
U.S. Geological Survey (USGS) scientists conducted field work efforts during February 15-23, 2017 and April 10-25, 2019 in the mangrove forests of Pohnpei, Federated States of Micronesia (FSM) with logistical assistance from the Micronesia Conservation Trust (MCT) and field assistance from the Conservation Society of Pohnpei and the Pohnpei Department of Forestry. The field team combined the surveying technologies and techniques of Real-Time Kinematic (RTK) Global Navigation Satellite System (GNSS) surveying, total station surveying, and differential leveling to measure elevations on critical features in the mangrove forests, including the elevations of water level recorders, sediment coring locations, and Surface...

This digital dataset was created as part of a U.S. Geological Survey study, done in cooperation with the Monterey County Water Resource Agency, to conduct a hydrologic resource assessment and develop an integrated numerical hydrologic model of the hydrologic system of Salinas Valley, CA. As part of this larger study, the USGS developed this digital dataset of geologic data and three-dimensional hydrogeologic framework models, referred to here as the Salinas Valley Geological Framework (SVGF), that define the elevation, thickness, extent, and lithology-based texture variations of nine hydrogeologic units in Salinas Valley, CA. The digital dataset includes a geospatial database that contains two main elements as GIS...

This model archive contains 20 Precipitation-Runoff Modeling System (PRMS) models for 20 catchments within the Lake Michigan watershed (Mei and others, 2022). PRMS is a process-based distributed deterministic watershed model designed for the simulation of hydrologic processes including evaporation, transpiration, runoff, infiltration, interflow, and groundwater flow (Markstrom and others, 2015). The PRMS model version 5.2.0 (Markstrom and others, 2015) within the Ground-water and Surface-water FLOW (GSFLOW version 2.2.0) modeling platform (Markstrom and others, 2008) was used to construct the 20 catchment models. Each of the catchment models was calibrated using six different calibration schemes that are either...
This dataset describes streamflow and precipitation event statistics for four watersheds located in Clarksburg, Maryland, USA. Streamflow and precipitation events were identified from fourteen years of sub-daily (5- and 15-minute) monitoring data from October 1, 2004 through September 30, 2018. A 6-hour inter-event window was used to define discrete streamflow and precipitation events. The following streamflow metrics were calculated for each event area normalized peak streamflow, runoff yield, runoff ratio, streamflow duration, time to peak, and rise rate. Precipitation event metrics include total precipitation depth and precipitation event duration.

This data release contains a comma-delimited ascii file of four same-day, discrete discharge measurements made at sites along selected reaches of Wailua Stream, Maui, Hawai'i on July 23, 2019. These discrete discharge measurements form what is commonly referred to as a “seepage run.” The intent of the seepage run is to quantify the spatial distribution of streamflow along the reach during fair-weather, low-flow conditions, generally characterized by negligible direct runoff within the reach. The measurements can be used to characterize the net seepage of water into (water gain) or out of (water loss) the stream channel between measurement sites provided that the measurements were made during stable, nonchanging...
On October 5-6, 2022, a combination of Acoustic Doppler Current Profiler (ADCP) and Global Navigation Satellite System (GNSS) surveying were used to collect bathymetric data of the Lummi Sea Pond near Bellingham, WA. Distributed XYZ points were interpolated to create a continuous bathymetric map of the sea pond. The final product is two-meter raster in NAD88 (2011) UTM 10N coordinates, with elevations referenced to NAVD88 (GEOID18a). Details of the process used to construct the surface are provided in the raster file metadata. Supporting datasets included in the zip file include raw ADCP data, ADCP bathymetry data in CSV format, and GNSS data in CSV format.

High-frequency observations of surface water at fine spatial scales are critical to effectively manage aquatic habitat, flood risk and water quality. We developed inundation algorithms for Sentinel-1 and Sentinel-2 across 12 sites within the conterminous United States (CONUS) covering >536,000 km2 and representing diverse hydrologic and vegetation landscapes. These algorithms were trained on data from 13,412 points spread throughout the 12 sites. Each scene in the 5-year (2017-2021) time series was classified into open water, vegetated water, and non-water at 20 m resolution using variables not only from Sentinel-1 and Sentinel-2, but also variables derived from topographic and weather datasets. The Sentinel-1 model...
The U.S. Geological Survey Dakota Water Science Center, in cooperation with the Federal Highway Administration, analyzed annual peak-flow data to determine if trends are present and provide attribution of trends where possible. Work for the national trend attributions for nonstationary annual peak-flow records was broken into seven regions that are loosely based off of two-digit hydrologic unit watershed boundaries. Each of the regions made attributions for nonstationary annual peak-flow records using both monotonic trends and change point for 50 (1966-2015) and 75 (1941-2015) year trends. Each child page contains four supporting comma separated values (csv) files (50-year monotonic, 75-year monotonic, 50-year change...
