Data

The 2022 Department of the Interior, Environment, and Related Agencies Appropriations Bill - the appropriations bill that funds the USGS - established a regional Integrated Water Availability Assessment study program in the Great Basin of the American West. Twenty saline lakes across California, Nevada, Oregon, and Utah were identified by USGS partners as priority ecosystems. They include: Califor

Geochemical data for aqueous, mine tailings, and sediment samples collected from the Big River and Meramec River drainage basins in southeastern Missouri are presented. The Big River drains historical lead, zinc, and barite mining districts, including the Old Lead Belt (OLB). Underground mining in the OLB resulted in large mine-waste chat piles and tailings impoundments that have released material

These data include in situ images of lake trout (Salvelinus namaycush) and round goby (Neogobius melanostomus) collected by an autonomous underwater vehicle (AUV) in Lakes Michigan and Superior in 2020 and 2021 and laboratory images of round goby collected by a GoPro in 2021. These images were collected and labeled to train and validate an algorithm for automated fish sizing and biomass estimation

The storage assessment unit (SAU) is the fundamental unit used in the National Assessment of Geologic Carbon Dioxide Storage Resources project for the assessment of geologic CO2 storage resources. The SAU is shown here as a geographic boundary interpreted, defined, and mapped by the geologist responsible for the assessment interval. Individual SAUs are defined on the basis of common geologic and h

Comma-separated values (.csv) file containing data related to mercury in biota collected from Clear Lake, California. This data release supersedes Pierce, J.R., Feyrer, F., Young, M., Enos, E., Clause, J., Alpers, C., and Eagles-Smith, C.A., 2022, Mercury in fishes from Clear Lake, California, 2019 and 2020 (ver. 2.0, February 2022): U.S. Geological Survey data release, https://doi.org/10.5066/P9

These data describe demographic (e.g, age), morphometric (body shape), and meristic (total number of gill rakers) measurements of a probable spawning run of cisco (Coregonus artedi) collected from the Spanish River (Ontario, Canada) immediately downstream of the Espanola Dam from 15-16 November 2022. These data were used to provide baseline biological, demographic, and morphological information on

Black Carp (Mylopharyngodon piceus) were imported to the United States for use as a biological control in aquaculture and have since escaped with reproducing populations in the wild. Habitat use and capture of this species has not been well documented in the wild, thus questions about catchability by gears and habitats are present. This dataset represents sampling effort to capture Black Carp with

These data were derived from hydroacoustic data collected by uncrewed surface vehicles (USVs) and powered research vessels in Lake Superior in 2022. The powered vessels overtook the USVs to study fish avoidance of survey vessels during traditional acoustic surveys. The water column was divided into four depth groups for analysis. Each USV transect was binned into 30-sec intervals and measured hydr

We used Adaptive Resolution Imaging Sonar (ARIS), which is based on Dual-Frequency Identification Sonar (DIDSON) technology to observe net encounter behaviors of bigheaded carps. Gill nets with four different mesh types (8.9 cm bar mesh) and trammel nets with five different mesh sizes (range 5.1-8.9 cm bar mesh) were evaluated. Net sets were undisturbed, or fish were driven with the noise of the o

This data release contains output from a numerical snow simulation for a 65 kilometer (km) × 81 km model domain in parts of Montana and Wyoming, United States, encompassing the Gallatin River watershed upstream of the U.S. Geological Survey streamgage near Gallatin Gateway, MT (06043500). Weather Research and Forecasting (WRF) Model convection-permitting and orography-resolving regional climate si

This dataset contains shoreline positions derived from available Landsat satellite imagery for four states (Texas, Louisiana, Mississippi, and Florida) along the U.S. Gulf coast for the time period 1984 to 2022. An open-source toolbox, CoastSat (Vos and others, 2019a and 2019b), was used to classify coastal Landsat imagery and detect shorelines at the sub-pixel scale. Resulting shorelines are pres

Black Carp collections (n=534) by commercial fishers, biologists, and recreational anglers from the Mississippi River basin recorded from 2018 to 2022 are reported here. Geographic coordinates, total length (TL), weight, girth, date of capture, sex, and gear were recorded. Total length was measured from the tip of the snout to the longest caudal fin ray with the caudal fin lobes pinched. Girth was
