High-resolution riverbed grain-size models of Oregon rivers High-resolution riverbed grain-size models of Oregon rivers
This data release includes rasters of riverbed grain size in select Oregon rivers where substrate size has been modeled following the approach of White and others (2025a) in which bathymetric lidar point-clouds were paired with georeferenced pebble counts to produce grain-size rasters for the Santiam River Basin (White and others, 2025b). Similar to White and others (2025b), this data...
High-resolution small uncrewed aircraft system (sUAS) and terrestrial lidar system (TLS) lidar datasets for border security within San Bernardino National Wildlife Refuge, AZ documenting invasive vegetation management and stream restoration, 2024 High-resolution small uncrewed aircraft system (sUAS) and terrestrial lidar system (TLS) lidar datasets for border security within San Bernardino National Wildlife Refuge, AZ documenting invasive vegetation management and stream restoration, 2024
The U.S. Geological Survey collected low-altitude airborne lidar data via a small uncrewed aircraft system (sUAS) and terrestrial lidar system (TLS) for quantifying surficial conditions along the Black Draw ephemeral stream channel in the U.S. Fish and Wildlife Service (USFWS) San Bernardino National Wildlife Refuge (SBNWR) in Arizona in February 2024. Data collection was during the...
Historical (1900s-1940s) and present-day (2003 – 2023) spring Chinook salmon (Oncorhynchus tshawytscha) spawning distribution in the Willamette River Basin, Oregon Historical (1900s-1940s) and present-day (2003 – 2023) spring Chinook salmon (Oncorhynchus tshawytscha) spawning distribution in the Willamette River Basin, Oregon
Spawning distribution maps for Upper Willamette River (UWR) spring Chinook salmon were created for the historical period (approximately 1910-1940), and for the present-day period (2003-2023). These maps were created as a tool to visualize generalized, reach-scale patterns of spawning distribution before and after the construction of high-head dams and other large-scale anthropogenic...
Historical Flood Typing Classifications for Select River Basins across the Conterminous United States Historical Flood Typing Classifications for Select River Basins across the Conterminous United States
This metadata record describes historical flood type classifications and causal attribution data for the FEMA-funded joint U.S. Geological Survey and U.S. Army Corps of Engineers Mixed Populations Flood Frequency Project. The data listed here include classifications of historical flood peaks based on causal mechanisms determined using manual and semi-automated methods at select locations...
Horizontal-to-Vertical Spectral Ratio (HVSR) Soundings and Depth-to-Bedrock Data for the Moreau Lake Area, Town of Moreau, Saratoga County, N.Y. (2017 - 2020) Horizontal-to-Vertical Spectral Ratio (HVSR) Soundings and Depth-to-Bedrock Data for the Moreau Lake Area, Town of Moreau, Saratoga County, N.Y. (2017 - 2020)
This data release contains Horizontal-to-Vertical Spectral Ratio (HVSR) data collected between 2017 and 2020 from 73 locations in the area surrounding Moreau Lake, Saratoga County, New York. The HVSR technique, commonly referred to as the passive-seismic method, is used to estimate the thickness of unconsolidated sediments and the depth to bedrock (Lane and others, 2008; Fairchild and...
Hormone levels and morphometric data of male Burmese pythons (Python bivittatus) in South Florida Hormone levels and morphometric data of male Burmese pythons (Python bivittatus) in South Florida
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.
Hosts, pathogens, and hot ponds: Thermal variability and heat contribute jointly to spatial patterns of chytrid infection in amphibians in southern Wisconsin, data release Hosts, pathogens, and hot ponds: Thermal variability and heat contribute jointly to spatial patterns of chytrid infection in amphibians in southern Wisconsin, data release
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...
Housatonic River watershed hydraulic models and supplementary data for stream crossings in Massachusetts Housatonic River watershed hydraulic models and supplementary data for stream crossings in Massachusetts
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...
Humboldt River Basin Model Grids and Potential Groundwater Capture Results Humboldt River Basin Model Grids and Potential Groundwater Capture Results
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
Hydraulic models and supplementary data for 30 stream crossing sites in Massachusetts Hydraulic models and supplementary data for 30 stream crossing sites in Massachusetts
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...
Hydro-Climatological Analysis of Riparian Vegetation along the San Carlos River and Lower Reaches of the Gila River of the Upper Gila River Watershed: 2019 to 2023 Hydro-Climatological Analysis of Riparian Vegetation along the San Carlos River and Lower Reaches of the Gila River of the Upper Gila River Watershed: 2019 to 2023
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...
Hydroacoustic and environmental data from autonomous underwater vehicle (AUV) in Lakes Superior and Michigan, 2022 Hydroacoustic and environmental data from autonomous underwater vehicle (AUV) in Lakes Superior and Michigan, 2022
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
