Observations of irrigated agricultural land within the San Simon Valley Groundwater Subbasin of the Safford Groundwater Basin in Arizona. Crops were verified in situ twice in 2024, first on May 31st and again on Sep 20th; based on digitized field boundaries. Field boundaries were digitized from U.S. Department of Agriculture, National Agriculture Imagery Program County Mosaic 2023...

This data release contains water temperature and specific conductance data from Lake Koocanusa at the international boundary (USGS site number 12300110) from November 2024 to April 2025. Data were collected every 30 minutes at depths of 3 meters (m) and 10 m below the water surface. These data were collected as part of a water-quality monitoring program in Lake Koocanusa to provide data...

A new 30 meter resolution polygon data layer of the islands of the United States, with associated attributes describing key physical and conservation geography characteristics. Islands were grouped into a three-tiered hierarchy of island provinces (12), island regions (28), and individual islands (a total of 19,023 islands were extracted). Islands were classified as estuarine vs non...

This data release provides shapefiles of surface rupture mapping, interferometric synthetic aperture radar (InSAR) data, finite fault modeling inputs, parameters, and outputs, and optical image cross-correlation displacement data derived from high-resolution satellite imagery to accompany the manuscript “Thompson Jobe and others, Surface Rupture From an Aftershock: Remote Observations...

Population growth and recurring droughts in the Black Hills region of western South Dakota and eastern Wyoming raised concerns regarding water resources and its future availability. Drought conditions in the late 1980s and the early 2000s stressed local water systems relying heavily on surface water as the population of the region was increasing. In response to water-availability...

Concentrations of individual polychlorinated biphenyl (PCB) congeners, polycyclic aromatic hydrocarbons (PAHs), and chlorinated pesticides are reported for surface sediments collected along the nearshore of Bellingham Bay, the Nooksack River, and four urban creeks discharging to Bellingham Bay in March 2019. Additional samples were collected along the nearshore urban waterfront corridor...

This dataset records Cladophora and associated benthic algae, collectively the Cladophora community or submerged aquatic vegetation (SAV), biomass collected during the growing season of 2024 at stations located along the U.S. shoreline of Lakes Michigan, Huron, Erie, and Ontario. It also records a variety of supporting data collected at Cladophora measurement stations. These supporting...

This data release contains shapefiles of the hydrogeologic provinces of the conterminous United States. The United States Geological Survey (USGS) is developing a National Extent Hydrogeologic Framework (NEHF). In support of that effort, the conterminous United States was subdivided into eight hydrogeologic provinces that are generally based on geologic provinces and subprovinces...

This study used artificial burrowing chambers to investigate the effects of groundwater drainage rates and soil type on burrow initiation and morphology of red swamp crayfish (Procambarus clarkii). The relationship between caloric density of crayfish and burrowing was also examined. The objectives of this study were to (1) determine the effect of ground water drainage rates on burrowing...

The USGS is conducting a long-term study of a terrestrial crude oil spill that resulted from a ruptured pipeline in 1979. Samples of oil bailed from wells were analyzed for polyaromatic hydrocarbons by a commercial lab. A total of 32 samples were analyzed in three batches. A sample that serves as a surrogate for the original spilled oil was submitted with each batch. For each oil sample

To enhance hurricane coastal impact models, we developed 1-m land cover maps for the coastal portions of states along the Gulf of America and Atlantic coasts using recent (2018–2020) high-resolution orthoimagery and moderate-resolution land cover maps. Our first step was to develop land cover maps with three classes (vegetated, unvegetated, water) using recently acquired 1-m orthoimagery...

This data release contains raster datasets representing depth to water table, calculated from steady-state groundwater models developed by the U.S. Geological Survey (Jahn and others, 2024; Barclay and others, 2024). The depth to water table rasters are available at an approximate resolution of 10 meters. In addition, depth to water table, hydrologic soil types, and landcover are...
