Physical and chemical changes affect the biota within urban streams at varying scales ranging from individual organisms to populations and communities creating complex interactions that present challenges for characterizing and monitoring the impact on species utilizing these freshwater habitats. Salmonids, specifically cutthroat trout (Oncorhynchus clarkii) and coho salmon (Oncorhynchus kisutch), extensively utilize small stream habitats influenced by a changing urban landscape. This study used a comprehensive fish health assessment concurrent with the U.S. Geological Survey’s Pacific Northwest Stream Quality Assessment in 2015 to quantifiy impacts from disease in juvenile coho and cutthroat salmon, impacts to...

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 of the reservoir. Surficial grab samples of bed material were collected at 27 locations representing the left, right or center of the channel cross-section where sampling was possible using a Ponar sampler. Sediment cores were collected with a Vibracore at 12 locations at or near the surficial grab sample transects, and discrete sediment...

This data release includes hourly water temperature data at 12 locations in the main stem of the Quinault River and its major tributaries, and data from a riparian vegetation survey conducted in the lower Quinault River, Washington. Water temperature data was collected during the summer of 2018 and 2019 at most locations. Variable collection periods by site are described within the dataset. Riparian vegetation surveys were conducted during the summer of 2018.

This dataset describes the quantity and morphology of microplastics in water, sediment, fish, and mussel samples from the Delaware River and select tributaries, including portions of the Upper Delaware Scenic & Recreational River, Middle Delaware National Scenic River, Delaware Water Gap National Recreation Area, and Lower Delaware Scenic & Recreational River. Water and sediment samples were collected at nine locations, from Callicoon, New York, at the upstream end, to Burlington, New Jersey, at the downstream end. Smallmouth bass (Micropterus dolomieu), white sucker (Catostomus commersonii), and eastern elliptio (Elliptio complanata) were sampled at a subset of locations to assess biological uptake of microplastics....

This dataset describes the quantity and morphology of microplastics in water, surficial sediment, sediment core, fish, and shellfish samples from Lake Mead National Recreation Area (Nevada/Arizona). Water and surficial sediment samples were collected once at 9 locations. A sediment core (33 cm long) was extracted from Las Vegas Bay to assess changes in microplastic deposition over time. Striped bass (Morone saxatilis), common carp (Cyprinus carpio), quagga mussels (Dreissena bugensis), and Asian clams (Corbicula fluminea) were sampled at a subset of locations to assess biological uptake of microplastics. Sampling and analysis methods are described in the Processing Steps section of the metadata. All samples were...

These data were collected to characterize the quantity and quality of microplastic particles found in 17 streams in the northeastern United States, from New York to Virginia. USGS staff who represent the Urban Landscapes Capabilities Team (ULCT) within the North Atlantic-Appalachian Region designed the study and collected the water samples on which the data are based. Data were collected during 2017 and 2018 and included a baseflow and stormflow sample at each site. Additionally, the various microplastic particles in each sample were characterized by one of two different size-fraction categories (categories of 355-1000 micrometers and 1000-5600 micrometers), by type of particle (fiber/line, fiber clump, bead/pellet,...

Smelter slag, containing copper and other trace elements, is widespread in riverbed sediments in the Upper Columbia River near Kettle Falls, WA. To evaluate the potential risk to aquatic life, concentrations of copper and other trace elements were measured in the shallow pore and surface water collected near the sediment-water interface. An in situ pore-water profiler was used to collect a suite of four water samples from above, at, and below the sediment-water interface at each of 11 sampling locations. Samples were collected between July 19-21, 2017. The analysis of water samples included specific conductance, pH, alkalinity, dissolved organic carbon, and a suite of major anions, cations, and trace elements.

From 2018 to 2024 surface waters (fresh and brackish), groundwater, and stormwater (runoff, re-use) samples were collected from sites with varying landuse (agricultural, forested, and urban) and streamflow conditions and analyzed at the Organic Geochemistry Research Laboratory in Lawrence, Kansas for the tire antioxidant 6PPD (6-p-phenylenediamine; N-(1,3-Dimethylbutyl)-N’-phenyl-p-phenylenediamine) and ozonated transformation product 6PPD-quinone (6PPD-Q, 2-((4-Methylpentan-2-yl)amino)-5-(phenylamino)cyclohexa-2,5-diene-1,4-dione)). There were 78 urban sampling sites in Colorado (N=15), Connecticut (N=1), Georgia (N=1), Hawaii (N=22), Kansas (N=7), Michigan (N=1), Minnesota (N=1), North Carolina (N=1), Oklahoma...

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.

This release includes all data collected in support of a juvenile Chinook salmon exposure study designed to understand the retention of microplastic clothing fibers (hereon refered to as "microfibers") after feeding. To understand the potential impacts of microfiber ingestion to fish, we ran a feeding experiment with juvenile Chinook salmon to determine if ingested fibers are retained and/or digestion rates altered over a full, experimentally determined, 10 day digestion period. Data includes: fish weights, microfiber counts, and quality assurance (QA) data for the experiment. QA steps are detailed in the process section of the metadata.
