These data were compiled in support of the Post-2026 Operational Guidelines and Strategies for Lake Powell and Lake Mead (Post 2026) Environmental Impact Statement (EIS). These data were outputs from models that estimate annual minimum dissolved oxygen and daily water temperature in the Colorado River below Glen Canyon Dam. The objective of our study was to predict water temperatures and...

Two data files are included. The first includes GPS locations (~ 22k) of adult brown pelicans (n = 7) and the second includes characteristics of foraging trips (n = 552) from these same seven birds. Pelicans were outfitted with GPS satellite tags during incubation and data collected for the longevity of the tag. Movement data were used to define use areas during the breeding season...

This data release provides the concentration and quality-assurance results for inorganic constituents analyzed in water-quality samples from 26 residential and commercial tapwater locations in Montana by the U.S. Geological Survey (USGS) Environmental Health Program (EHP), Tapwater Exposure Study. The samples were collected between June 10-12, 2024, from both public supply (8) and...

Lakes in the Midwestern United States support valuable recreational, subsistence, and tribal fisheries. Fisheries assessments that support management decisions are typically conducted within political boundaries and at intervals that limit their spatial and temporal scope. Data aggregation across lakes and regions facilitates research extending across ecological gradients and...

This data release reports the concentration results for organic compounds (disinfection byproducts [DBP], pesticides, per- and polyfluoroalkyl substances [PFAS], pharmaceuticals and volatile organic compounds [VOC]), cyanotoxins, microbiological indicators, as well as radon-222 analyzed in samples collected from private well and public supply sourced tapwater samples from a community in...

This data release provides digital flight line data for a high-resolution airborne magnetic and radiometric survey over the Hartville Uplift and Shirley Mountains regions of Wyoming. The survey is split into two blocks, one covering the Hartville Uplift region (Block A), and the other covering the Shirley Mountains region (Block B). The airborne survey was mainly funded by the State of...

This dataset contains discharge measurements derived from acoustic Doppler current profiler (ADCP) observations collected at U.S. Geological Survey (USGS) stream gage locations that are observable by the Surface Water and Ocean Topography (SWOT) satellite. ADCP measurements were compiled for the period 2015 through December 1, 2025 and paired with reach-scale median SWOT-observed water...

This data release includes the revised downscaled climate inputs and hydrologic outputs from the Basin Characterization Model (BCM) version 8 (v8), described in Flint and others (2021a), in a 30 by 30-meter spatial resolution at a monthly time step from water years 1896 to 2024 for the upper Feather River watershed. This data release includes five child items: 1. 30-year summaries, 2...

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...

We conducted a multi-year study (2016-2019) to identify elements of wetland habitat management that could potentially benefit breeding ducks. Specifically, we examined the influence of habitat variables in explaining habitat selection of managed wetlands near upland nesting sites by radio-tagged Mallard (Anas platyrhynchos) and Gadwall (Mareca strepera) ducklings in a brackish marsh...

The Edwards aquifer in south-central Texas is one of the most permeable and productive aquifers in the United States and is the major source of public water supply for Bexar, Comal, Hays, Medina, and Uvalde Counties. The Edwards aquifer also supplies large quantities of water for use in agriculture, business, and industry in the region. The major artesian springs of the Edwards aquifer...

This data release was produced by the U.S. Geological Survey (USGS) in cooperation with the Bureau of Reclamation (Reclamation) to present the results of monitoring efforts on the Yellowstone River fish bypass channel according to the specifications of the Lower Yellowstone Adaptive Management and Monitoring Plan. The fish bypass channel was constructed to provide upstream migrating fish...
