Irrigation water use reanalysis for the 2000-20 period by HUC12, month, and year for the conterminous United States (ver. 2.0, September 2024) Irrigation water use reanalysis for the 2000-20 period by HUC12, month, and year for the conterminous United States (ver. 2.0, September 2024)
This data release provides a monthly irrigation water use reanalysis for the period 2000-20 for all USGS Watershed Boundary Dataset of Subwatersheds (HUC12) in the conterminous United States (CONUS). Results include reference evapotranspiration (ETo), actual evapotranspiration (ETa), irrigated areas, consumptive use, and effective precipitation for each HUC12. ETo and ETa were estimated...

Surficial geologic map database of the Aztec 1-degree by 2-degree quadrangle, northern New Mexico and southern Colorado: Contributions to the National Geologic Map Surficial geologic map database of the Aztec 1-degree by 2-degree quadrangle, northern New Mexico and southern Colorado: Contributions to the National Geologic Map
This data release presents geologic map data for the surficial geology of the Aztec 1-degree by 2-degree quadrangle. The map area lies within two physiographic provinces of Fenneman (1928): the Southern Rocky Mountains province, and the Colorado Plateau province, Navajo section. Geologic mapping is mostly compiled from published geologic map data sources ranging from 1:24,000 to 1:250...
Data on dietary preference by brown treesnakes on Guam Data on dietary preference by brown treesnakes on Guam
These data address experimental evaluations of dietary preference by captive brown treesnakes on Guam. Snakes were collected from the wild in areas with birds present and in areas without birds present 2018–2019. Snakes were then run through preference trials during which they were offered first live lures (mouse and finch) in snake traps on opposite sides of the arena. On the second...
Guam, USGS Closed Population (NWFN), an experimental eradication of brown treesnakes in a 5-ha study site, 2016 - 2023 Guam, USGS Closed Population (NWFN), an experimental eradication of brown treesnakes in a 5-ha study site, 2016 - 2023
These data represent a case study on managing the invasive brown treesnake (Boiga irregularis) on Guam within a 5 ha snake enclosure located on Northern Guam. The site code (NWFN or North West Field North) reflects a location on Andersen Air Force Base, Northern Guam, which has been a study site for close to two decades. The experimental process followed an adaptive resource management...
Topographic survey data and digital elevation model of Oxbow Reservoir, Placer County, California, October 2022 Topographic survey data and digital elevation model of Oxbow Reservoir, Placer County, California, October 2022
This data release presents topographic survey data and a digital elevation model (DEM) of Oxbow Reservoir, in Placer County, California. The U.S. Geological Survey (USGS) conducted a topographic survey of accessible regions of the reservoir sediment on 26 October 2022, when the reservoir was partially de-watered to allow repairs to the dam infrastructure following the Mosquito Fire. The...
