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.

Model-Estimated, Spatially Distributed Monthly Water Balance of the Upper Colorado River Basin, Water Years 1913-2017 Model-Estimated, Spatially Distributed Monthly Water Balance of the Upper Colorado River Basin, Water Years 1913-2017
Dataset was generated by performing water-balance computations for the Upper Colorado River Basin for the months October 1913 through September 2017. The basin area was first divided into 17,626 4-kim grid cells, and these were then grouped by sub-basin and annual precipitation into 960 subareas; the dataset includes a lookup table for this grouping. For each of the 960 subareas, the...
Native and Non-Native Fish Species in the Willamette River Basin, Oregon Native and Non-Native Fish Species in the Willamette River Basin, Oregon
The Willamette River Basin, Oregon, supports native fish species and non-native fish species introduced for sport fisheries or accidentally from aquarium releases and other sources. Based on fish surveys completed from 1998 to 2018 by Oregon State University and records from the Oregon State University Ichthyology Collection, the Willamette River Basin has 34 native fish species found...
Stillwater Complex, Montana: Logs of core drilled by Chrome Corporation of America in the Mountain View area, 1988 to 1990 Stillwater Complex, Montana: Logs of core drilled by Chrome Corporation of America in the Mountain View area, 1988 to 1990
This dataset includes TIFF (Tagged Image File Format) images of graphic drill core logs showing associated drill core information, a TIFF image of the explanation for the lithology and structure sections of the logs, an Esri shapefile of the locations of the drill holes, and 17 individual .csv files of tabular data that were compiled from handwritten drill core logs. The drill core is...
Structural measurements and their calculated surface traces, South Kawishiwi area, Duluth Complex, Minnesota Structural measurements and their calculated surface traces, South Kawishiwi area, Duluth Complex, Minnesota
This dataset includes a point shapefile representing structural measurements taken from a study area near the South Kawishiwi Intrusion in the Duluth Complex, Minnesota and a line shapefile representing the surface traces of the structural measurements. The structural measurements point file consists of a compilation of data from multiple published and unpublished sources. The surface...
Electrical resistivity tomography (ERT) and horizontal-to-vertical spectral ratio (HVSR) data collected East and Southeast of Ellsworth Air Force Base, South Dakota, in 2021 Electrical resistivity tomography (ERT) and horizontal-to-vertical spectral ratio (HVSR) data collected East and Southeast of Ellsworth Air Force Base, South Dakota, in 2021
This data release contains electrical resistivity tomography (ERT) and passive seismic data collected east of Ellsworth Air Force Base, South Dakota, from April to September 2021. The data accompanies a USGS scientific investigations map from Medler (2022). The U.S. Geological Survey, in cooperation with the U.S. Air Force Civil Engineer Center, used surface geophysical methods to...
