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.

Datasets from the focus group series of stakeholder engagement efforts to inform integrated water availability assessment data delivery Datasets from the focus group series of stakeholder engagement efforts to inform integrated water availability assessment data delivery
The U. S. Geological Survey- Water Resources Mission Area is currently developing Integrated Water Availability Assessments (IWAAs) - multi-extent (regional and national), stakeholder driven, near real-time water availability census and prediction for human and ecological uses. To provide appropriate user accessibility to data delivery systems developed for IWAAs, a user-centered design...
Surface-water transfers and removals in the Pacific drainages of the United States Surface-water transfers and removals in the Pacific drainages of the United States
This data release contains a comprehensive, spatially referenced database of surface-water transfer and removal events in the Pacific drainages of the United States, which include the Columbia River basin, the Puget Sound basin, the coastal drainages of Washington, Oregon, and California, and the Central Valley of California. The database also includes mean annual estimates of the water...
STEPS: Slip Time Earthquake Path Simulations applied to the San Andreas and Toe Jam Hill faults to redefine geologic slip rate uncertainty (Matlab code) STEPS: Slip Time Earthquake Path Simulations applied to the San Andreas and Toe Jam Hill faults to redefine geologic slip rate uncertainty (Matlab code)
Geologic slip rates are a time-averaged measurement of fault displacement calculated over 100s- to 1,000,000-year time scales and are a primary input for probabilistic seismic hazard analyses (PSHA), which forecast expected ground shaking in future earthquakes. Despite their utility for seismic hazard calculations, longer-term geologic slip rates represent a time-averaged measure of the...

Age, Trace Metal, Stable Isotope, and Fatty Acid Data Collected from Sturgeon Captured in the Mississippi and St. Croix Rivers, Minnesota and Wisconsin, 2015-2016. Age, Trace Metal, Stable Isotope, and Fatty Acid Data Collected from Sturgeon Captured in the Mississippi and St. Croix Rivers, Minnesota and Wisconsin, 2015-2016.
Proposed invasive carp barriers may threaten populations of migratory fishes in the St. Croix National Scenic Riverway and the Mississippi National River and Recreation Area by preventing movements between rivers needed to fulfill life history requirements. Moreover, reproducing populations of invasive carp could alter aquatic food webs and negatively affect mussels and migratory fishes...
Data Release for PGV Data for the 2018 National Seismic Hazard Model for the Conterminous United States Data Release for PGV Data for the 2018 National Seismic Hazard Model for the Conterminous United States
Peak ground velocity (PGV) gridded probabilistic seismic hazard data for the updated 2018 National Seismic Hazard Model (NSHM) for the Conterminous United States (CONUS). PGV hazard curves and ground motions have been calculated on a 0.05 by 0.05 degree grid using the NSHM CONUS 2018 earthquake source model. PGV support has been incorporated into the NSHM using a newly developed PGV...
