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.

Upper Klamath Lake and Clear Lake sampling for suckers from 2015 through 2022 Upper Klamath Lake and Clear Lake sampling for suckers from 2015 through 2022
Data in this data set include effort expended to collect suckers for cohort tracking and metrics and observations for each sucker captured from 2015 through 2022. There are two levels of data. All Nets data contains 5102 records and the data file is 609 KB. Captures data contains 3764 records and the data file is 504 KB. The data files can be linked by setID which is a unique identifier...
Geochemical data for water, sediment, and biota in areas affected by historical mining, northwestern Sierra Nevada and Trinity Mountains, California Geochemical data for water, sediment, and biota in areas affected by historical mining, northwestern Sierra Nevada and Trinity Mountains, California
This dataset includes data for water, sediment, and biota samples collected at 250 locations in the northwestern Sierra Nevada and the Trinity Mountains during 1999–2012. The locations were chosen to assess potential effects from historical mining, with a focus primarily on mercury contamination associated with placer gold mines in the Sierra Nevada and the Trinity Mountains, and a hard...
Model Archival Summary for Suspended-Sediment Concentration at U.S. Geological Survey Site 06887000, Big Blue River near Manhattan, Kansas, during July 2018 through August 2023 Model Archival Summary for Suspended-Sediment Concentration at U.S. Geological Survey Site 06887000, Big Blue River near Manhattan, Kansas, during July 2018 through August 2023
Note: this data release has been superseded by version 2.0, available here: https://doi.org/10.5066/P13YQYVQ This model archival summary summarizes the suspended-sediment concentration (SSC; U.S. Geological Survey [USGS] parameter code 80154) model developed to compute 15-minute, hourly, or daily SSC from July 26, 2018, onward. This model is specific to USGS site 06887000, the Big Blue...
Root and Shoot Lengths of Rice and Bermuda Grass Seedlings Inoculated with Endophytic Bacteria from Phragmites australis Root and Shoot Lengths of Rice and Bermuda Grass Seedlings Inoculated with Endophytic Bacteria from Phragmites australis
These data include measurements of root and shoot lengths of Rice (Oryza sativa) and Bermuda grass (Cynodon dactylon) that were inoculated with nine endophytic bacterial isolates. The tabular data represent growth promotion and fungal infection susceptibility information. They also show the infection rate of F. oxysporum on Rice (Oryza sativa), Bermuda grass (Cynodon dactylon) and Annual...
Geochemical data for post-fire surface water, streambed sediment, and soils from areas affected by the 2018 Camp Fire, Butte County, California Geochemical data for post-fire surface water, streambed sediment, and soils from areas affected by the 2018 Camp Fire, Butte County, California
During November 2018, the Camp Fire burned more than 150,000 acres in Butte County, California. The fire was the deadliest and most destructive in California history, destroying more than 18,000 structures and causing at least 85 fatalities. The U.S. Geological Survey sampled surface water in areas affected by the Camp Fire, plus an unburned control site, during two post-fire sampling...
Compilation of total dissolved solids concentrations and specific conductance measurements in the Upper Colorado River Basin, 1894 – 2022 Compilation of total dissolved solids concentrations and specific conductance measurements in the Upper Colorado River Basin, 1894 – 2022
This data release contains total dissolved solids (TDS) concentrations and specific conductance (SC) measurements collected at surface-water monitoring locations and groundwater monitoring wells within the Upper Colorado River Basin (UCRB) between 1894 and 2022. Discrete TDS and SC results were obtained from the Water Quality Portal (WQP). Continuous SC monitoring results were obtained...
