This data release contains analytical results of organohalogenated compounds and mercury in lamprey and sediment that were collected from rivers in Oregon and along the Pacific northwest coast from 2017 to 2021. In 2017, 20 lamprey were collected off the Washington and Oregon coasts by the National Oceanic and Atmospheric Administration. These ocean-caught juvenile lamprey were parasitizing targeted fish and were bycatch. In 2019, larval lamprey were collected by the Confederated Tribes of Warm Springs of Oregon from 8 sites on the Warm Springs Reservation. Larval lamprey were collected by electroshocking depositional sediment areas. Collocated depositional sediment samples also were collected along with the larval...

These datasets are one component of the multistressor studies conducted in Midwest streams in 2013 (MSQA) and in Southeast streams in 2014 (SESQA) by the U.S. Geological Survey National Water Quality Assessment Project. High-frequency small-volume autosamplers were deployed at 7 sites each in MSQA and SESQA that collected daily and weekly composite water samples, which were analyzed for 225 pesticides and pesticide degradates. Five of the MSQA autosampler sites were in agricultural watersheds and two in urban watersheds, whereas all seven SESQA autosampler sites were in urban watersheds. The daily and weekly composite samples were compared with results from traditional discrete water samples collected weekly at...

Temperature loggers were placed on the ground (n=4) and hung in the air (n=2) near the upstream connection point of four Willamette River off-channel features (side channels and alcoves) to assess timing and discharge conditions when these four off-channel features were inundated at the upstream end with flow from the main channel. Temperature readings indicate that the upstream end of an off-channel feature is inundated when the ground temperature sensor does not match nearby air temperature readings, indicating the ground sensor is submerged by river water. Temperature loggers were installed from late May through mid-November, 2016, when discharge of the Willamette River was between approximately 5,500 and 45,000...

Bees were collected in 24 fields across eastern Iowa in summer 2019. This data collection was part of a pesticide study funded by the USGS Ecosystems Mission Area- Environmental Health Program. Bees were collected using the sweep net method and then were immediately placed on dry ice in the field. Bees were kept frozen to prevent degradation. In the lab, each wild bee was photographed from one or more angles using an AmScope microscope fitted with an MU1400 digital camera at 20x magnification. Bees were then morphologically identified based on the images. All images were checked for quality control before they were archived on this site. This data release includes 1) a text file with bee identifications and image...

Bathymetric data were collected over all boatable areas of Upper Klamath and Agency Lakes, located in South-Central Oregon, in May and June of 1996. Areas that were too shallow (less than 1.2m) and/or covered with aquatic vegetation were not mapped. A 21ft tunnel-hull boat was fitted with an adjustable transducer mount on the stern. The transducer was mounted on the starboard side of the prop to minimize prop noise interference. A global positioning system (GPS) "rover" receiver's antennae mast was mounted directly above the transducer and connected to a Trimble 4000 GPS receiver. Differential correction updates were provided to the Trimble receiver at 1 second intervals from an OmniStar (John Chance Co., Houston,...

A three-dimensional groundwater flow model, MODFLOW 6, was developed to provide a better understanding of the hydrogeology of the Harney Basin, southeastern Oregon. The model was used to investigate the historical groundwater-level decline and storage loss associated with anthropogenic groundwater demands. The model was calibrated to 1930 through 2018 conditions. This USGS data release contains all of the input and output files for the simulation described in the associated model documentation report (https://doi.org/10.3133/sir20241518)
The U.S. Geological Survey (USGS) is developing SPARROW models (SPAtially Related Regressions On Watershed Attributes) to assess the transport of contaminants (e.g., nutrients) through the Pacific drainages of the United States (the Columbia River basin; the coastal drainages of Washington, Oregon, and California; the Klamath River basin; the Central Valley of California, and the west slopes of the Sierra Nevada Mountains). SPARROW relates instream water quality measurements to spatially referenced characteristics of watersheds, including contaminant sources and the factors influencing terrestrial and aquatic transport. Cattle manure applied to grazing land is a potential source of nutrients delivered to streams....

Dissolved pesticides were measured in weekly water samples from 85 wadeable streams in Central Coastal California over a variable six-week period during March–May, 2017, as part of the California Stream Quality Assessment (CSQA) study conducted by the U.S. Geological Survey's (USGS) Regional Stream-Quality Assessment (RSQA) Project. The 85 streams consisted of 40 urban sites (5–100% urban land in the lower basin), 9 agricultural sites, 24 mixed land-use sites, and 12 undeveloped sites. Water samples were filtered (0.7 micrometers) and analyzed for 253 pesticide compounds by direct-injection liquid chromatography with tandem mass-spectrometry (LC-MS/MS). Two similar LC-MS/MS methods were used: a broad-spectrum (223...

Water-quality data and plankton samples were collected at multiple locations within the Fernhill Natural Treatment wetland and along the Tualatin River, located to the west of Portland, Oregon, during the summers of 2018, 2019 and 2020. Water quality parameters collected include water temperature, specific conductance, dissolved oxygen, pH, turbidity, chlorophyll, and blue green algae. Data were collected to better understand how water discharged from the upstream natural treatment wetland (Fernhill Wetlands) affect algal species and water quality in the Tualatin River.
The USGS has published United States water-use data every five years since 1950. To increase the temporal and spatial availability of water use estimates using nationally consistent methods, the USGS is developing national water-use models for each major water-use category. This data release publishes crop irrigation withdrawals for the conterminous United States (CONUS) that are calculated using modeled irrigation consumptive use (Martin and others, 2023), irrigation efficiencies, and source-water proportions (Dieter and others, 2018). Crop irrigation withdrawals and irrigation consumptive use refer to water removed and consumed, respectively, from a groundwater or surface-water source to produce agricultural crops....
