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.

Watershed Model Input Data for the Great Basin Hydrologic Province and a portion of the Northern Mojave Desert Watershed Model Input Data for the Great Basin Hydrologic Province and a portion of the Northern Mojave Desert
This U.S. Geological Survey data release presents watershed model input point data aggregated for the Great Basin Hydrologic Province and a portion of the Northern Mojave Desert. The original source data was aggregated onto a 200-meter grid, and then converted to a point dataset with each point representing the centroid of a grid cell. The dataset includes information on elevation...
Factors affecting the spatial distribution of Niangua Darters (Etheostoma nianguae) in the Osage River basin, Missouri, USA, 2010-2011 Factors affecting the spatial distribution of Niangua Darters (Etheostoma nianguae) in the Osage River basin, Missouri, USA, 2010-2011
These data include information from 74 sampled stream reaches in the Osage Ecological Drainage Unit (EDU) within the Osage River Basin, Missouri. Streams with a Strahler order from three to six were systematically sampled to assess Niangua darter resource selection across three spatial scales macrohabitat, reach, and watershed scale. Variables used to explain Niangua darter presence at...
The reproductive development of wild-caught Black Carp Mylopharyngodon piceus in North America related to size and age at maturation from 2015 through 2023 The reproductive development of wild-caught Black Carp Mylopharyngodon piceus in North America related to size and age at maturation from 2015 through 2023
This study provides data on the reproductive biology and age of Black Carp (Mylopharyngodon piceus) from various rivers in the Mississippi River Basin. A total of 549 fish samples, collected opportunistically between 2015 and 2023, underwent macroscopic and histological staging to assess reproductive development. Specimens were captured by commercial fishermen and biologists and sent to...
Survival and bioaccumulation data for sensitive salmonids exposed to 6PPDQ with additional survival data for two bass species Survival and bioaccumulation data for sensitive salmonids exposed to 6PPDQ with additional survival data for two bass species
This data set includes survival data for five fish species [Coho Salmon (Oncorhynchus kisutch); Brook Trout (Salvelinus fontinalis); Rainbow Trout (Oncorhynchus mykiss); Smallmouth Bass (Micropterus dolomieu); Largemouth Bass (Micropterus nigricans)] exposed to various concentrations of 6PPD-quinone (6PPDQ) for up to 96 hours and then held in clean water for one week post exposure...
Effects of traffic on the establishment and spread of invasive annual grasses: an annotated bibliography produced through a structured literature search and semi-automated content analysis Effects of traffic on the establishment and spread of invasive annual grasses: an annotated bibliography produced through a structured literature search and semi-automated content analysis
This data release includes citation details, abstracts, and results of a semi-automated content analysis for 88 publications we identified on the topic of the potential effects of traffic from oil and gas development on invasive annual grasses. Our goal was to develop a structured literature search and semi-automated content analysis process to compile and provide an initial...
Fish captures in the Cuyahoga River, OH, USA from 1984-2024 Fish captures in the Cuyahoga River, OH, USA from 1984-2024
Data include counts and locations of fish captured in the mainstem of the Cuyahoga River from 1984 through 2024. Data were collected by USGS (2022-2024) and the Ohio Environmental Protection Agency (1984-2021) using standardized electrofishing techniques. Data also include site variables such as physical and chemical properties as well as dam removals that occurred within the river basin...
Behavioral response of crayfish to light and the effects on trapping success, laboratory and pond trials, Missouri 2022-2023 Behavioral response of crayfish to light and the effects on trapping success, laboratory and pond trials, Missouri 2022-2023
Data were collected in association with the application of visible light in laboratory and field settings to elicit behavioral responses from the invasive virile crayfish (Faxonius virilis). Data for laboratory light trials include water temperature, dissolved oxygen, and conductivity, crayfish sex, weight and size, light lux, proportion of time spent in each zone (lit versus unlit)...
Shorthead and silver redhorse movement data from Lake Erie and the Sandusky and Cuyahoga Rivers, Ohio USA from 2022 to 2025 Shorthead and silver redhorse movement data from Lake Erie and the Sandusky and Cuyahoga Rivers, Ohio USA from 2022 to 2025
Data include locations where shorthead redhorse (Moxostoma macrolepidotum) and silver redhorse (Moxostoma anisurum) were detected following tagging events in the Sandusky and Cuyahoga Rivers, Ohio, USA. Location data were obtained primarily through stationary acoustic receivers, with additional locations from radio towers and mobile acoustic and radio surveys in the Cuyahoga River. The...
USGS EcoDrought Streamflow and Water Temperature Data from Submersible Pressure Transducers in Massachusetts, Colorado, Idaho, and Oregon USGS EcoDrought Streamflow and Water Temperature Data from Submersible Pressure Transducers in Massachusetts, Colorado, Idaho, and Oregon
The U.S. Geological Survey (USGS) Water Mission Area (WMA) - Ecosystems Mission Area (EMA) EcoDrought project is comprised of interdisciplinary teams across the United States focused on the nexus between drought and ecosystem processes. To characterize streamflow conditions in EcoDrought study areas, gage height (stage) and water temperature data were collected using submersible pressure
Electro-olfactory and behavioral responses of grass carp, bighead carp, silver carp, and black carp to chemical stimuli in laboratory exposures Electro-olfactory and behavioral responses of grass carp, bighead carp, silver carp, and black carp to chemical stimuli in laboratory exposures
Using juvenile individuals of four species of carp (Family: Cyprinidae), we tested the potential for two amino acids and one commercial bait stimulus to elicit an extracellular electro-olfactory response within the naris using gelatin-based electrodes. The amino acids alanine and lysine were tested on grass carp (Ctenopharyngodon idella), bighead carp (Hypophthalmichthys nobilis), silver...
Fluvial Fish Richness Metrics for Stream Reaches of the NHDPlusV2.1 in the Conterminous United States Fluvial Fish Richness Metrics for Stream Reaches of the NHDPlusV2.1 in the Conterminous United States
This geopackage contains 18 fluvial fish species richness for ~2.3 million stream reaches from the NHDPlusV2.1 in the Conterminous United States. Metrics were developed using 415 fluvial fish species distribution models and highlight four types of summary metrics including all modeled species, migratory species, species of greatest conservation need, and fish species. Nine metrics are...
Thiaminase I activity measurements in juvenile black carp, bighead carp, grass carp, and silver carp from lab cultures Thiaminase I activity measurements in juvenile black carp, bighead carp, grass carp, and silver carp from lab cultures
We measured juveniles from four species, black carp (Mylopharyngodon piceus), bighead carp (Hypophthalmichthys nobilis), silver carp (H. molitrix), and grass carp (Ctenopharyngodon idella), for thiaminase activity. These data provide previously unknown information about thiaminase activity of three emerging threats (bighead carp, black carp, and grass carp) to the Great Lakes. We tested...
