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.

Physical and hydraulic monitoring on the Yellowstone River fish bypass channel, Montana Physical and hydraulic monitoring on the Yellowstone River fish bypass channel, Montana
This data release was produced by the U.S. Geological Survey (USGS) in cooperation with the Bureau of Reclamation (Reclamation) to present the results of monitoring efforts on the Yellowstone River fish bypass channel according to the specifications of the Lower Yellowstone Adaptive Management and Monitoring Plan. The fish bypass channel was constructed to provide upstream migrating fish...
Whole rock geochemical data for ore and host rock for select iron oxide-apatite and iron oxide-copper-gold deposits found in the Basin and Range province of California, Nevada, and Utah collected 2023-2024 Whole rock geochemical data for ore and host rock for select iron oxide-apatite and iron oxide-copper-gold deposits found in the Basin and Range province of California, Nevada, and Utah collected 2023-2024
This data release encompasses whole rock geochemical data determined on iron ore and host rock samples collected in California, Nevada, and Utah from March 2023 through June 2024. Whole rock geochemistry was conducted on 269 samples. Major element oxides were determined by borate fusion and wavelength dispersion X-ray fluorescence; 61 elements were determined by sodium peroxide fusion...
Mechanisms of Devils Lake’s Responses to Recent Climatic Wetting: Insights from a Physically Based Hydrologic Model Mechanisms of Devils Lake’s Responses to Recent Climatic Wetting: Insights from a Physically Based Hydrologic Model
These data cover Devils Lake Basin of Northern Great Plains (NGP) region, North Dakota. We aimed to understand the mechanism of the Devils Lake responses and basin-wide hydrologic change under a wet-climatic regime using a process-based and cold region hydrologic model. The data include areal measurements (km2) of each of the Hydrological Response Units (HRUs) that were modeled.
Data for Analysis of Decadal Trends in the Quality of Groundwater Used for Public Drinking-Water Supply in California, 2004-2023, California GAMA Priority Basin Project Data for Analysis of Decadal Trends in the Quality of Groundwater Used for Public Drinking-Water Supply in California, 2004-2023, California GAMA Priority Basin Project
This data release documents datasets supporting analysis of decadal trends in the quality of groundwater resources used for public drinking-water supply across California. The analysis primarily utilizes samples collected by the U.S. Geological Survey's Groundwater Ambient Monitoring and Assessment Priority Basin Project (GAMA-PBP) during 2004-2023 as part of a cooperative research...
Regional invasive annual grass simulation models and invaded cover across the sagebrush biome (2022-2042) Regional invasive annual grass simulation models and invaded cover across the sagebrush biome (2022-2042)
This data release contains spatially explicit state-and-transition simulation model (STSM) packages, simulation results, and projected invaded cover layers of Invasive annual grasses (IAG). IAGs continue to spread within the sagebrush biome of the western United States, and managers need ways to scope IAG management strategy effectiveness for long-term strategic planning. We developed a...
Data from petrological and geochemical analyses of fast pyrolysis bio-oil distillation residues and naturally formed solid fossil fuels Data from petrological and geochemical analyses of fast pyrolysis bio-oil distillation residues and naturally formed solid fossil fuels
Distillation of fast pyrolysis bio-oils leaves solid residues analogous to those from distillation of fossil fuels or from natural subsurface petroleum formation (i.e., solid bitumen) or other natural carbon concentration processes (e.g., coal formation). Much like petroleum-based residues, bio-oil residues vary in terms of quality, yield, and versatility for downstream applications. For...
