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.

Longitudinal profiles of water temperature in Mill Creek, Mason County, Washington, measured using fiber-optic distributed temperature sensing (FO-DTS) Longitudinal profiles of water temperature in Mill Creek, Mason County, Washington, measured using fiber-optic distributed temperature sensing (FO-DTS)
This data release contains fiber-optic distributed temperature sensor (FO-DTS) data for three reaches of Mill Creek collected during two deployments between August 20, 2020, and September 4, 2020. Spatially continuous profiles of water temperature were collected with a Sensornet® Oryx DTS FO-DTS. At each of the three reaches, water temperature was spatially averaged over 1.015-meter...
Elemental concentrations for bulk and size-fractionated mine waste from the Tar Creek Superfund Site, Tri-State Mining District, Oklahoma, U.S.A. Elemental concentrations for bulk and size-fractionated mine waste from the Tar Creek Superfund Site, Tri-State Mining District, Oklahoma, U.S.A.
Elemental concentrations for bulk and size-fractionated mine waste from sampled historical waste piles from the Tar Creek Superfund Site, Oklahoma, U.S. were determined after dissolution via acid digests or a sodium peroxide fusion. Elemental concentrations were determined for the leachate from a simulated rainwater leach of mine wastes. Data and methods reported are part of a research...
Electron microprobe analyses of sphalerite and hemimorphite from mine wastes from the Tar Creek Superfund Site, Tri-State Mining District, Oklahoma, U.S.A. Electron microprobe analyses of sphalerite and hemimorphite from mine wastes from the Tar Creek Superfund Site, Tri-State Mining District, Oklahoma, U.S.A.
Electron microprobe analyses of sphalerite (ZnS) and hemimorphite (Zn4Si2O7(OH)2·H2O) from sampled historical waste piles were conducted with a specific focus on germanium (Ge). In mine wastes at the Tar Creek Superfund Site, Oklahoma, USA, Ge is associated with ZnS (sphalerite) as expected, but weathering in the waste piles has led to a significant amount of Ge being incorporated into a...
Dissolved arsenic, copper, and lead concentrations in surface water within the Klamath Basin (ver. 3.0, October 2022) Dissolved arsenic, copper, and lead concentrations in surface water within the Klamath Basin (ver. 3.0, October 2022)
Arsenic (As) toxicity is a global environmental and health problem. There are both natural (eg volcanic activity) and anthropogenic sources of As (eg lead arsenate and copper arsenate were commonly used pesticides in the 1900's). Aqueous levels of arsenic in the Klamath Basin (CA, OR), which has a volcanic origin, can exceed at some locations both the Oregon Department of Environmental...
Quinault River water temperature and salmon bioenergetics model data Quinault River water temperature and salmon bioenergetics model data
This data release contains the complete set of modeling input and output files for a Heat Source water temperature model and fish bioenergetics model on the lower Quinault River in Washington state. A detailed description of the modeling process, results, and interpretation can be found in the associated primary publication.
Sediment chemistry and characteristics of samples collected in 2019 from the Similkameen River above Enloe Dam, Okanogan County, Washington (ver. 3.0, March 2022) Sediment chemistry and characteristics of samples collected in 2019 from the Similkameen River above Enloe Dam, Okanogan County, Washington (ver. 3.0, March 2022)
This data release provides information on the chemistry and character of bed sediments accumulated in the 1.6-mile long impoundment behind Enloe Dam on the Similkameen River in Okanogan County, WA. Sediment samples were collected during four weeks in October – December 2019. The sampling locations were distributed among 10 transects that ranged from 0.1-0.2 miles apart along the length...
