The upper Cedar River Municipal Watershed (CRMW) is managed by Seattle Public Utilities and provides habitat that sustains an isolated adfluvial population of Endangered Species Act-listed bull trout (Salvelinus confluentus). Bull trout spawning in the CRMW begins in early fall when the water surface elevation of Chester Morse Lake and the stream discharges in its major tributaries, the...

Assessing the spatial variation in accretion rates and soil properties helps increase understanding of tidal wetland processes and can be used to calibrate model of long-term wetland resilience. Nine deep soil cores (50-100 centimeters) were sampled across tidal flat, tidal marsh, and upland transition areas across Morro Bay estuary. Short (7 centimeters) soil cores were also sampled...

This data release contains eight luminescence samples collected for USGS Science Investigations Map, "Quaternary geologic map of the Mesquite Springs fault zone, San Bernardino County, California", of the Mesquite Hills (north of Ludlow CA about halfway between I-15 and I-40). The samples were analyzed by infrared stimulated luminescence (IRSL) and produced ages between ~33 ka and ~200...

This dataset includes a collection of files related to a project investigating concentrations of per- and polyfluoroalkyl substances (PFAS) in biotic and abiotic compartments of five stream food webs in the Farmington River watershed, Connecticut, USA. The dataset contains aqueous, sediment, and tissue concentrations of 28 PFAS compounds, 19 of which were detected at least once. Aqueous

This data release provides digital flight-line and gridded data for a high-resolution airborne magnetic and radiometric survey over a part of southwest Utah. The survey was acquired as part of the UGSS Earth Mapping Resource Initiative (Earth MRI) to improve our understanding of the fundamental geologic framework of the region with applications to evaluating natural resources and...

Data include treatment water chemistry data (Chlorine concentration, Dissolved oxygen, water conductivity, pH, alkalinity, and hardness) and condition of test plants evaluated 24 hours after testing and then every 4 days for 30 days. Treatment water chemistry data was collected at the beginning and end of the plant treatment period and a subset of times during the treatment period. Plant...

This data release includes thiamine concentration measurements from lake trout (Salvelinus namaycush) eggs and associated biological data (e.g., fish length, weight, sex) and capture location data (e.g., lake, coordinates, date of collection). Lake trout used in this dataset were collected during 2025 from across the Great Lakes and other inland lakes such as the Finger Lakes, New York...

We examined enhanced turbulence levels as an alternative grass carp (Ctenopharyngodon idella) control strategy through turbulence-induced mortality at embryonic stages. We exposed pre-water-hardened and water-hardened grass carp eggs to increased levels of turbulence in a grid-stirred turbulence tank to find threshold values of turbulence parameters and shear stresses that have lethal...

The U.S. Geological Survey, in cooperation with Broward County Environmental Planning and Resilience Division, has developed a groundwater/surface-water model to evaluate the response of the drainage infrastructure and groundwater system in Broward County to increases in sea level and potential changes in precipitation. The model was constructed using a modified version of MODFLOW-NWT...

A Geographic Information System (GIS) shapefile and summary tables of irrigated agricultural land-use are provided for Glades, Highlands, Martin, Okeechobee, and St. Lucie Counties, Florida. These files were compiled through a cooperative project between the U.S. Geological Survey and the Florida Department of Agriculture and Consumer Services, Office of Agricultural Water Policy...

This report compiles structural orientations of rock fabrics measured at outcrops of metamorphic and plutonic rocks in part of the Ruby Mountains metamorphic core complex. Measurements are reported for foliations, lineations, elongation mylonitic lineations, fold axes, fold asymmetry, and fold axial planes, many of which are plotted directly on the Geologic map of the Ruby Dome...

This data release includes field observations and laboratory data for two trenches excavated across the Lost River fault zone, Idaho, in September 2019. The field sites include the Sheep Creek site (44.282541 degrees N, 113.941193 degrees W) on the southernmost Warm Springs section and the Arentson Gulch site (44.247816 degrees N, 113.918554 degrees W) on the northernmost Thousand...
