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.

National Hydrologic Model v1.0 water budget components aggregated to 10 and 12-digit Hydrologic Unit Code boundaries National Hydrologic Model v1.0 water budget components aggregated to 10 and 12-digit Hydrologic Unit Code boundaries
This data release contains the output of the National Hydrologic Hydrologic Model (NHM) version 1.0 aggregated to twelve-digit and ten-digit Hydrologic Unit Code (HUC) boundaries contained in the NHDPlus v2.1 dataset. The data are intended to provide "local" water budgets for each HUC boundary as total aggregated streamflow across HUC boundaries is not included. The HUC boundaries are...
MODFLOW-NWT and MT3D-USGS models for appraising parameter sensitivity and other controlling factors in a synthetic watershed accounting for variably-saturated flow processes MODFLOW-NWT and MT3D-USGS models for appraising parameter sensitivity and other controlling factors in a synthetic watershed accounting for variably-saturated flow processes
A 3-dimensional (3D) synthetic model, using MODFLOW-NWT and MT3D-USGS, explores the new unsaturated zone heat transport capabilities in MT3D-USGS. Model simulations were used to explore various parameter sensitivities and unsaturated zone thicknesses and their impact on heat transport as water enters the subsurface as infiltration, flows through the unsaturated zone to the water table...
MODFLOW-NWT and MT3D-USGS models for evaluating heat flows, lags and dampening under high emission climate forcing for unsaturated/saturated transport in a synthetic watershed MODFLOW-NWT and MT3D-USGS models for evaluating heat flows, lags and dampening under high emission climate forcing for unsaturated/saturated transport in a synthetic watershed
A 3-dimensional (3D) synthetic model, built for running with MODFLOW-NWT and MT3D-USGS, explores the new unsaturated zone heat transport capabilities in MT3D-USGS. Model simulations explore potential responses to within a watershed to climate warming along system pathways. The response analysis uses output from a 30-year warming period on a synthetic watershed patterned after a humid...
MODFLOW-NWT, MT3D-USGS, and VS2DH models of 6 hypothetical 1-dimensional variably saturated systems to demonstrate the accuracy of new heat transport capabilities in MT3D-USGS MODFLOW-NWT, MT3D-USGS, and VS2DH models of 6 hypothetical 1-dimensional variably saturated systems to demonstrate the accuracy of new heat transport capabilities in MT3D-USGS
Six hypothetical 1-dimensional models are used to verify and demonstrate new unsaturated-zone heat transport functionality added to MT3D-USGS (version 1.1.0). Because the governing equations describing groundwater solute transport and heat transport have a similar form, MT3D-USGS may be applied to heat transport problems. Published examples of MT3DMS, from which MT3D-USGS is derived, as...
Stem and Needle Growth for Whitebark Pine in the Sierra Nevada Stem and Needle Growth for Whitebark Pine in the Sierra Nevada
These data represent stem growth, needle length growth, and carbon stable isotope ratios from whitebark pine at 27 sites in the Sierra Nevada of California. Values for stem growth were derived from increment cores, processed following standard methods. Needle characteristics were captured for individual trees across all years needles were present on the internodes. Needle length was...
Drilling, construction, geophysical, water quality, and aquifer test data for well SEP 16, Butte County, Idaho Drilling, construction, geophysical, water quality, and aquifer test data for well SEP 16, Butte County, Idaho
In 2021 and 2022, the U.S. Geological Survey (USGS), in cooperation with the Idaho Department of Water Resources (IDWR), drilled and constructed well SEP 16 (431900112593601) approximately 6 miles south-southeast of Big Southern Butte in Butte County, Idaho. The purpose of the well installation was to collect geologic, geophysical, and hydrologic data. On July 13, 2022, the USGS Idaho...
