Data

Hormone levels (corticosterone, testosterone) and associated sampling information (date, year, month, reproductive season, sampling location, time to bleed) from free-ranging male invasive Burmese pythons (Python bivittatus) in South Florida. Dataset also includes morphometric data (mass, length, circumference, age) of each individual male sampled during the years of 2018 to 2024.

Data was collected to evaluate how are temperature variability and heat related were to Batrachochytrium dendrobatidis infection in eastern newts (Notophthalmus viridescens) in 23 freshwater ponds in southeastern Wisconsin, USA. We collected data on water temperature, pond characteristics, amphibian species presence, and Batrachochytrium dendrobatidis infection by collecting skin swabs...

The U.S. Geological Survey (USGS), in cooperation with the Massachusetts Department of Environmental Protection (MassDEP), developed one-dimensional U.S. Army Corps of Engineers (USACE) Hydrologic Engineering Center’s River Analysis System (HEC-RAS) hydraulic models for stream crossing sites in the Housatonic River watershed, Massachusetts. An automated Geographic Information System (GIS...

This U.S. Geological Survey data release presents polygon model grids and tables of 100-year groundwater capture results for the lower, middle, and upper Humboldt River basins, Nevada. The grids define the active model cells, including cell identifiers and elevations for the model layers. The tables summarize potential groundwater capture from three sources: stream depletion, salvaged

The data in this Data Release are used to calibrate a Geographic Information System (GIS) based hydraulic modeling tool developed by the U.S. Geological Survey (USGS) for Massachusetts in cooperation with the Massachusetts Department of Environmental Protection (MassDEP). USGS developed one-dimensional U.S. Army Corps of Engineers (USACE) Hydrologic Engineering Center’s River Analysis...

Riparian systems across the southwestern United States are immensely important ecosystems and serve as biodiversity hotspots for a number of plant and animal species. However, recent challenges including non-native vegetation expansion, increased wildfire activity, and widespread vegetation die-offs, have substantially impacted the conditions of these ecosystems. This study was...

This dataset contains hydroacoustic and environmental data collected by a long-range autonomous underwater vehicle (LRAUV) in U.S. waters of Lake Superior and Lake Michigan during August 2022. Data were collected to evaluate bias in fisheries hydroacoustic surveys associated with the surface acoustic dead zone (SADZ; 0–5 m depth), where near-surface fish often go undetected, leading to

This data release includes hydroacoustic data for the 2023 to 2025 water years at one station. This station is part of a discrete and continuous monitoring project in embayments on Long Island Sound to support nutrient management activities in Connecticut. The data were collected by the U.S Geological Survey (USGS) in cooperation with the Connecticut Departments of Energy and...

The upper portion of the Troublesome Aquifer is the sole source of water for domestic use in the Greater Pole Creek Basin, situated in the western portion of the upper Fraser River Valley in Grand County, Colorado. Data from drilling records for wells installed near and within recent home developments, municipal water-suppliers, water-quality records, and published reports are summarized...

This data release contains hydrologic and water quality data collected as part of an investigation into the hydrology of Moreau Lake, in Moreau Lake State Park, Town of Moreau, Saratoga County, New York (Heisig, 2026). These data include: 1) discrete and 2) continuous comparison measurements of lake-water levels adjacent groundwater levels at well SA1305, 3) measurements of groundwater...

The U.S. Geological Survey, in cooperation with the City of Brownsville, Texas, configured and calibrated a set of hydrologic models for a 217-square-mile study area in Cameron County in South Texas. The Hydrological Simulation Program—FORTRAN (HSPF) modeling system was used to simulate the hydrological conditions for the study area because it is one of the most comprehensive watershed...

In May 2025, the U.S. Geological Survey (USGS) National Uncrewed Systems Office (NUSO) conducted uncrewed aircraft system (UAS) flights to collect hyperspectral and thermal remote sensing imagery over dryland sites during a collaborative field campaign near Moab, Utah. Two sites, "Horsethief Campground" and "Salt Valley", which have differing vegetation and soil characteristics, were...
