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.

Hydrogeologic Data from the Cahuilla Valley and Terwilliger Valley Groundwater Basins, Riverside County, California, 2022 (ver. 2.0, August 2025) Hydrogeologic Data from the Cahuilla Valley and Terwilliger Valley Groundwater Basins, Riverside County, California, 2022 (ver. 2.0, August 2025)
The U.S. Geological Survey (USGS) entered into a cooperative study with the California Department of Water Resources and the Ramona Band of Cahuilla to characterize the hydrogeology of the Cahuilla Valley and Terwilliger Valley groundwater basins and surrounding water-bearing units, with the ultimate goal of developing a calibrated integrated hydrologic model to manage the groundwater...
Occurrence of plants in plots along the Gunnison River, Colorado, 1990-2017 Occurrence of plants in plots along the Gunnison River, Colorado, 1990-2017
In 1990 the US Geological Survey Fort Collins Science Center and National Park Service Water Resources Division established 133 permanent 1meter (m) X 2 m plots along the Gunnison River near Warner Point in Black Canyon of the Gunnison National Park. A one-dimensional hydraulic model was calibrated to determine the inundation necessary to inundate each plot, and this can be combined with...
Chemistry data for assessment of the containment pond at Pinyon Plain Mine, 2021 Chemistry data for assessment of the containment pond at Pinyon Plain Mine, 2021
These data are comprised of measurements of elements (e.g., uranium, cobalt, nickel, copper, zinc, cadmium, lead, etc.), major anions (chloride, nitrite+nitrate as nitrogen, sulfate, etc.), organic carbon, and general water quality characteristics in Pinyon Plain Mine containment pond water, invertebrate, vegetation and sediment samples, collected in calendar year 2021.
Brook trout imagery data for individual recognition with deep learning Brook trout imagery data for individual recognition with deep learning
This Data Release provides imagery data for the development of deep-learning models to recognize individual brook trout (n=435). Images were collected at the Paint Bank State Fish Hatchery (Paint Bank, VA) on August 9, 2021 using a GoPro Hero 9 camera mounted approximately 50 cm above a fish board. The Paint Bank State Fish Hatchery is operated by the Virginia Department of Wildlife...
Hawaiian Islands bioclimatic variables for baseline and future climate scenarios Hawaiian Islands bioclimatic variables for baseline and future climate scenarios
We integrated recent climate model projections developed for the State of Hawai’i with current climatological datasets to generate updated regionally defined bioclimatic variables. We derived updated bioclimatic variables from new projections of baseline and future monthly minimum, mean, and maximum temperature (Tmin, Tmean, Tmax) and mean precipitation (Pmean) data at 250 m resolution...
Central Valley Hydrologic Model version 2 (CVHM2): Land Use Properties (ver. 3.0, October 2023) Central Valley Hydrologic Model version 2 (CVHM2): Land Use Properties (ver. 3.0, October 2023)
This digital dataset contains three types of information about the land use properties used in the updated Central Valley Hydrologic Model (CVHM2): land use shapefile showing primary land use type for a model cell through time, soil data using the curve number for each region and zone, and farm process parameter values including crop coefficients and rooting depths.
