Data

The U.S. Geological Survey (USGS) supports multiple efforts to understand and predict storm impacts to our nation’s coastlines. The first infrastructure line is defined as the seaward boundary of the first row of structures or roads in a coastal area and can be used to assess coastal vulnerability. The first infrastructure line as defined in this dataset represents a cross shore boundary...

The Fish and Wildlife Service currently uses nets and electrofishing as part of their early detection and monitoring program in the Upper Illinois River for bigheaded carps. This dataset contains the sampling data and sampling attributes (such as water parameters for electrofishing or net length for gills). The sampling data is the binary presence/absence observations. This is that data...

This dataset describes fishes associated with the lower Colorado River basin in central Texas. The dataset is comprised of 1,835 records of individual fishes collected by boat electrofishing at 36 sites in Bastrop, Travis, Fayette, and Colorado counties from December 2014 through September 2017. Each record reports the collection date, county, river basin, gear type, scientific name...

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...

Fish genetics data and the location of populations of Yellowstone cutthroat trout (Oncorhynchus virginalis bouvieri; formerly Oncorhynchus clarkii bouvieri). Surveys were collected in tributaries and rivers within the upper Snake River basin, Wyoming. These datasets were created to be used in genetic stock identification to evaluate the effect of tributary populations on population...

Floating aquatic vegetation (FAV) are plants that float freely on or just below the water's surface and with roots that are not attached to a solid substrate but rather float in the water column. Accurate detection of FAV is needed in remotely sensed data products as discrimination between wetland and water classes is hindered in the presence of aquatic vegetation. The spectral...

This dataset contains site information and flood-frequency analysis results using station skew for 253 streamgaging stations operated by the U.S. Geological Survey (USGS) across Colorado within the Rio Grande Basin and Missouri, Arkansas-White-Red, and Upper Colorado River Basins (2- digit hydrologic unit codes 13, 10, 11, and 14, respectively). Some streamgages included in this study...

This data release provides the source data and results of a flood frequency analysis for sites in the Mendenhall River Basin, Alaska, that was conducted using USGS PeakFQ software (Veilleux and others, 2014; Flynn and others, 2006). Data are provided for two streamgages that had at least 10 years of annual peak-flow record. The data include streamgage information, PeakFQ input (.txt and...

This USGS data release documents species distribution models for 419 fluvial fish species in their native ranges of the conterminous United States. Source data, supporting code and model results are documented in this data package. Boosted Regression Tree (BRT) models were used to develop presence/absence predictions for each of the National Hydrography Dataset Plus Version 2.1 stream...

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...

Flynn Creek crater is a ~3.8 km diameter, >200 m deep, flat-floored impact structure that formed ~360 Ma in what is now north-central Tennessee (36°17’ N, 85°40’ W) [1-4]. Between 1967 and 1979, USGS scientist Dr. David Roddy conducted a drilling program at Flynn Creek crater, an invaluable terrestrial analog that can be applied to the field of planetary impact cratering dynamics [5,6]...

This data release includes six child items with data related to bioenergetics and food web ecology in Shasta Reservoir from 2024 to 2025. Child Item 1: "Zooplankton and Water Temperature Data". This included data on zooplankton density and production (zooplankton_density.csv, zoop_length.csv, and daphnia_egg_ratio.csv) as well as water temperature vertical profiles (temperature_data...
