Macroinvertebrate samples were collected from streams tributary to Honnedaga Lake and from the Middle Branch of the Black River during 2012-2016 and analyzed for methylmercury concentrations and for stable isotope ratios of nitrogen and carbon. Macroinvertebrates were identified in the field, and the level of taxonomic resolution varied from order to species; most taxa were identified to the family level. Specimens were field-processed into composite samples, field-frozen, and submitted to the mercury laboratory for freeze-drying and analysis. Subsamples were then submitted to the stable isotope laboratory for analysis of nitrogen and carbon isotope ratios. This database contains the resulting data and associated...

A total of 27 temperature sensors were deployed along the lower 90 miles of the Yakima River at 7 locations where cold water had been previously observed. These 7 cold-water areas had 3 to 6 temperature sensors installed to document the extent and duration of these cold-water areas and their impacts on mainstem temperatures of the Lower Yakima River. Cold-water areas included the mouths of tributaries, alongside channels, and within alcoves. Sensor deployments ranged from 1 to 2 years beginning in October 2018. All temperature data are included in the Yakima.temperatures.zip folder. Details of each monitoring location are provided in the site.locs.csv file. In addition to the raw data and site location information,...

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 set, compiled by the USGS Lake Erie Biological Station, provides near-bottom measurements of temperature and dissolved oxygen for the Central Basin of Lake Erie. Data were recorded by self-contained environmental data loggers (PME, Inc., MiniDOT data loggers). The data loggers were deployed to collect data during August 2021 through November 2022 to better understand how hypoxia develops and influences fish habitat quality during lake stratification. The data loggers were deployed on acoustic telemetry receivers in a network designed to record tagged fish movements (Great Lakes Acoustic Telemetry Observation System, GLATOS). Additional years of data collection are planned, and data release will be updated...

Water, bed sediment, and biota were sampled in selected streams from Butte to near Missoula, Montana, as part of a monitoring program in the upper Clark Fork Basin of western Montana. The sampling program was led by the U.S. Geological Survey (USGS), in cooperation with the U.S. Environmental Protection Agency.

This dataset has been archived; it has been superceded by version 2.0 (September 2021) which can be found at https://doi.org/10.5066/P9RUUR4L Data from 10-day sediment toxicity tests of bed sediments from the Buffalo River Area of Concern (AOC) and reference reaches on the Buffalo River upstream of the AOC, Erie County, New York, respectively. Specifically, the data was used to compare the survival and growth of two macroinvertebrate species in sediments from study sites and laboratory controls. Results are from 10-day sediment exposures of two test species, Chironomus dilutus and Hyalella azteca. Sediment samples were collected from 8 sites within the AOC and from 6 reference sites upstream of the AOC. Bed-sediments...

This geospatial dataset includes one point feature class file and associated FGDC-compliant metadata representing datasets to support development of ecological limit functions for the Cumberland Plateau in northeastern Middle Tennessee and southeastern Kentucky. Knight and others (2012, 2014) developed a methodology of relating fish species richness to changes in hydrologic conditions for sites within the Tennessee River Basin; this dataset applies this methodology to 138 sites within the the Cumberland Plateau. Information contained within this dataset represents values of basin characteristics (see Table II in Knight and others, 2012), estimates of streamflow characteristics (see Table I in Knight and others,...

The data is supplemental to the 2018 USGS Open File Report, "An evaluation of the acute and chronic toxicity of potassium chloride, active compound in the molluscicide potash, on salmonid fishes and their forage base". This research was performed as a Science Support Partnership (SSP) study with USFWS in order to evaluate potential lethal and sublethal impacts of potassium chloride on salmonid fishes and selected invertebrate forage. Files in this data set describe blood chemistry parameters, plasma osmolality and cortisol, gill chloride cell abundance, and fish total body weight and total length for specimens from each of the two salmonid species tested (brook trout, Salvelinus fontinalis, and Chinook salmon, Oncorhynchus...

The recent completion of the US Army Corps of Engineers (USACE) Hurricane and Storm Damage Risk Reduction System (HSDRRS) for New Orleans has effectively blocked surface water exchange between Bayou Sauvage National Wildlife Refuge (BSNWR) and the surrounding Lake(s) Pontchartrain and Borgne and the Gulf of Mexico to which it was once connected. Monitoring changes in hydrology, water quality, bird habitat variability, and resident waterbird and nekton communities within BSNWR is important to the long-term sustainability of these aquatic resources for use by visitors and aquatic life in these habitats. In particular, landscape and hydrologic modifications from management and restoration projects in southeastern Louisiana...

This projects primary goal was to provide data on occurrence and abundance of SAV resources within the fresh to saline coastal waters of the northern Gulf of Mexico, and to relate these findings to key environmental variables. The data set provides the collected data from 2013, 2014 and 2015 on site location, discrete water quality, aquatic vegetation cover and biomass by species. The same 384 sites were collected each year, between June and September. This project was co-funded by the South Central Climate Adaptation Science Center and the Gulf Coast Prairie and the Gulf Coastal Plains and Ozarks Landscape Conservation Cooperatives.

Fish mercury (Hg) data were compiled for 392 unique locations on freshwater streams and rivers in New York State for the period 1969-2016. A total of 7620 records were compiled from state, federal, and non-governmental organization databases. The compiled data were for samples of 65 non-anadromous species or species groups in which Hg was analyzed in whole fish or edible flesh, and for which sufficient ancillary data were available for interpretation. This data release provides total Hg concentrations on a wet weight basis, ancillary sample data (e.g., fish length, body part analyzed), collection location information (description, latitude, longitude), and source of original data. The data release also contains...
