Data

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...

These data are a compilation of example index velocity ratings used at USGS streamgaging stations. Each directory contains seven comma-delimited files consisting of a read me, the hydrographer developed rating, a table of discharge measurements used to develop the velocity rating, a mixture model analysis, statistically recommended rating, and the variance covariance matrix for both the

This data release presents a national cross-section (XS) database (NXSDB) of bathymetric cross-sections collected during water year (WY) 2022 (October 1, 2021, to September 30, 2022). The WY 2022 NXSDB has been approved by the U.S. Geological Survey (USGS) for publication and supersedes the provisional versions. The data were collected by hydrographers during routine site visits to...

This data release presents a national cross-section (XS) database (NXSDB) of bathymetric cross-sections collected during water year (WY) 2023 (October 1, 2022, to September 30, 2023). The WY 2023 NXSDB has been approved by the U.S. Geological Survey (USGS) for publication and supersedes the provisional version. The data were collected by hydrographers during routine site visits to...

The Fraser River, located in the Colorado Rocky Mountains, is a headwater tributary to the Upper Colorado River. This investigation by the U.S. Geological Survey (USGS) Water Mission Area, Water Quality Processes Program Proxies Project was conducted from September 2021 through August 2023 and consisted of eight sampling events incorporating 17 sites (15 stream sites and two wastewater...

This study evaluated the use of stacked machine learning for wood species identification based on Laser Induced Breakdown Spectroscopy data. The approach combined three types of Support Vector Machine classifiers (linear, polynomial, and radial kernels) using a One-vs-All strategy. The outputs were combined through a Partial Least Squares Discriminant Analysis meta-learner. Variable...

A synthetic one-dimensional groundwater flow model was developed using MODFLOW 6 as a test application of the prior-based model discrimination method described in the associated publication (https://doi.org/10.1029/2025WR040323). The model represents a steady-state unconfined aquifer where water flows horizontally between two constant head boundaries (a lake at the lefthand side and...

Stakeholder engagement is essential to successful development and implementation of products and services supporting emergency management. Governmental agencies often have a unique challenge of ensuring equitable stakeholder representation across large geographic, administrative, and topical areas. This project used stakeholder engagement to understand end-users needs concerning water...

Paleogeologic information directly above (supracrop) and below (subcrop) geologic periods from U.S. Geological Survey (USGS) reports was digitized from scanned plates. Geologic periods maps include the Jurassic (McKee and Others, 1956), Triassic (McKee and Others, 1959), Permian (McKee and McKee, 1967), Pennsylvanian (McKee and Crosby, 1975), and Mississippian (Craig and Connor, 1979)...

Clear Lake, located in Lake County, California, is impacted by mercury contamination associated with the historic Sulfur Bank mercury mine, which is adjacent to the lake’s eastern shore / Oaks Arm region. As part of a larger study designed to better understand the biogeochemical cycling of mercury in Clear Lake, shallow sediment (top 0-2 cm or 0-4 cm) was sampled from the three major...

Dynamic Surface Water Extent (DSWE) annual proportions of total surface water processed to the continental US Analysis Ready Data (ARD) tile scheme (https://landsat.usgs.gov/ard_tile) in Sarbanes and Jones 2025 are here resampled to the 20 m Sentinel-2 satellite grid using bilinear interpolation with a 3 by 3 pixel moving window. The resulting 973 tiles, with values ranging from 0 to 100...

During August 2023, transient electromagnetic (TEM) surveys were carried out at select locations in Lake County near Leadville, Colorado upgradient from the Dinero tunnel bulkhead. TEM data were collected using an ABEM WalkTEM2 advanced instrument running acquisition software version 1.3.7.4 and using a single-turn transmitter loop (Tx) and a center-loop receiver (Rx). Tx loop dimensions...
