Data

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 glacial deposits underlying southeastern Michigan, northeastern Indiana, and northwestern Ohio are a substantial source of water to communities, agriculture, and industry in the region. The U.S. Geological Survey, in cooperation with the Ohio Environmental Protection Agency, used processed data from the State-managed collections of well records to develop a hydrogeologic framework of...

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...

This data release contains an image and video catalog of the 2018 summit collapse and lower East Rift Zone eruption of Kīlauea volcano, on the Island of Hawaiʻi. An intrusion of magma into Kīlauea’s lower East Rift Zone resulted in a four-month-long eruption from May 3 to September 5, 2018 (Neal and others, 2018). The eruption produced lava flows that covered an area of 35.5 square...

This data release makes available the data used to test and refine a remote sensing approach for estimating river discharge via critical flow theory. In rivers where flow conditions are near critical and well-defined standing waves are present, discharge can be inferred from measurements of wavelength and channel width made on an image. The goals of the study were to: 1) evaluate the

Mauna Loa volcano, Island of Hawaiʻi, erupted from November 27 to December 10, 2022, sending lava flows across the summit caldera (Mokuʻāweoweo) and into the upper Southwest Rift Zone, before focusing in the Northeast Rift Zone at fissure 3, sending a lava flow down the north flank that threatened a major highway (Zoeller and others, 2024). During the eruption, U.S. Geological Survey...

Climate often drives ungulate population dynamics, and as climates change, some areas may become unsuitable for species persistence. Unraveling the relationships between climate and population dynamics, and projecting them across time, advances ecological understanding that informs and steers sustainable conservation for species. Using pronghorn (Antilocapra americana) as an ecological...

These data were compiled to model ecosystem metabolism in the Glen Canyon Dam tailwater (e.g., the Colorado River below Glen Canyon Dam). The primary objective of our study was to develop a new ecosystem metabolism model which we refer to as the variable flow two-station (VFTS) model. The VFTS modifies the classic two-station metabolism approach to account for unsteady flow, thus...

Beginning in 2016, the U.S. Geological Survey, Environmental Health Program, Drinking Water and Wastewater Infrastructure Integrated Science Team, in collaboration with other federal, non-governmental and Tribal partners, began collecting and analyzing tapwater samples from across the Nation for a large suite of inorganic, organic, and biological contaminants (Bradley and others, 2025)...
