The U.S. Geological Survey (USGS) National Extent Hydrogeologic Framework for National Water Census (NEHF) project is a multi-year effort (2022 through 2025) that will compile existing assets (approaches, data, software, etc.), develop a strategic plan, and implement an operational framework that is dynamic and multi-scale. Within the USGS, numerical groundwater-flow and solute- and heat-transport models have been created for a variety of purposes that include water-resource assessments, contaminant-transport evaluations, and water-management planning. These models are often supported by hydrogeologic-framework studies that describe the surface and subsurface distribution of geologic materials and their hydrologic...

Anaerobic microcosm experiments were conducted in April-May 2018 with PFAS-contaminated soil from a U.S. Army installation (Fort Drum, New York) and simulated groundwater. All microcosms, except for a live sediment control, were amended with perfluorooctanesulfonate (PFOS), perfluorooctanoate (PFOA), and 6:2 fluorotelomer sulfonate (6:2 FtS). Replicate treatments were prepared with and without bioaugmentation with the WBC-2 dehalogenating culture and with and without addition of chlorinated volatile organic compounds (1,1,2,2-tetrachloroethane and trichloroethylene). Two additional treatments were prepared containing granular activated carbon. All microcosms were prepared in duplicate and sacrificed for sampling....

The dataset contains a hybrid bathymetric-topographic digital elevation model (DEM) of the Upper Missouri River near Wolf Point, MT. The DEM was generated within ArcGIS by compositing bathymetric data from multiple single beam sonar surveys collected between June 2018 and July 2019 with previously existing topographic data collected from airborne LiDAR into a triangulated irregular network (TIN). The resulting TIN was then manually edited and exported as a raster for use in developing a hydrodynamic model.

Note: this data release is currently being revised and is temporarily unavailable The U.S. Geological Survey (USGS) Water Resources Mission Area (WMA) is working to address a need to understand where the Nation is experiencing water shortages or surpluses relative to the demand for water need by delivering routine assessments of water supply and demand and an understanding of the natural and human factors affecting the balance between supply and demand. A key part of these national assessments is identifying long-term trends in water availability, including groundwater and surface water quantity, quality, and use. This data release contains Mann-Kendall monotonic trend analyses for 18 observed annual and monthly...

Risk assessments describe the risk of a species’ invasion in a location, and many risk assessments have been produced by different institutions for various reasons. However, information is sporadically located online, increasing the difficulty of developing comprehensive lists of species with risk assessments or comparing assessment results across species in locations of interest. Therefore, we aggregated species risk assessments by searching information systems and conducting a literature review. The methods for data aggregation are explained in the larger work citation (Dean et al. 2024). The present dataset documents risk assessments available at different spatial scales (e.g., territory, state, region, nation)...

In January 2024 adult monarch butterflies (Danaus plexippus (Linnaeus, 1758)) were found dead near their overwintering site in Pacific Grove, Monterey County, California, USA. Ten of the deceased monarchs (six females and four males) were collected from three sites by staff at the Pacific Grove Museum of Natural History and sent to the U.S. Geological Survey Organic Chemistry Research Laboratory for analysis. Each individual adult monarch was analyzed following methods in Black et al., 2023 and Gross et al., 2024a and 2024b for 181 pesticides and pesticide transformation products; 15 pesticides were detected and included 8 insecticides/insecticide transformation products, 2 fungicides, and 4 herbicides/herbicide...

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. This dataset, termed "GAGES II", an acronym for Geospatial Attributes of Gages for Evaluating Streamflow, version II, provides geospatial data and classifications for 9,322 stream gages maintained by the U.S. Geological Survey (USGS). It is an update to the original GAGES, which was published as a Data Paper on the journal Ecology's website (Falcone and others, 2010b) in 2010. The GAGES II dataset consists of gages which have had...

This dataset contains two subsets of animations corresponding to particle tracking simulations of the Upper Missouri River near Wolf Point, MT comparing larval transport through the upper and lower sub-reaches of the larger model reach. Animations do not contain audio and depict particles moving from the top of the reach (left side) to the bottom of the reach (right side). A total of 96 animations are included corresponding to a combination of 1 of both reaches (upper or lower), 1 of 16 discharges (185-635 cms, at increments of 30 cms), and 1 of 3 vertical movement methods (active60pct, active75pct, or passive).

Continuous water-temperature data were collected at multiple restoration sites along the Middle Fork and mainstem Willamette Rivers between Jasper and Newberg, Oregon, to support effectiveness monitoring for a large-scale channel and floodplain restoration initiative (Willamette Focused Investment Partnership, WFIP). Continuous water-temperature loggers were deployed at a subset of WFIP sites where river restoration activities were planned or implemented to improve habitat conditions for native fish species. Data from water-temperature monitoring will be used to evaluate the effectiveness of restoration activities at improving habitat conditions for native fish in the Willamette River. Additionally, water-temperature...

This dataset contains breakthrough curves calculated from particle tracking simulations of a July 1, 2019, larval drift experiment conducted on the Upper Missouri River near Wolf Point, MT. Breakthrough curves were generated using a custom script written in the Python programming language that counts the number of particles per time step passing through sampling locations. Breakthrough curves were generated for particles using passive, active75pct, and active60pct vertical movement methods at the first two sampling stations downstream of the release location.

This data release includes output data from the transit-loss accounting program for the Fountain and Monument Creek watersheds in El Paso and Pueblo Counties, Colorado. The output data distinguish between native and reusable streamflow. Native streamflow is that which originates naturally within the watershed. Reusable streamflow originates as water imported from outside the watershed, water derived from pumping of certain groundwaters, or as other water with rights that allow it to be reused. The program accounts for reusable water throughout the watershed, as well as the total inflow and outflow of water to each subreach division within the watershed. The accounting program is based upon stream-aquifer models...

This dataset includes well logs used in the creation of the Cincinnatus hydrogeologic framework. Well logs were used from multiple sources (DEC, DOT, NWIS) and were a crucial component in generating hydrogeologic layer elevations and thicknesses. Well logs are available in their original form on GeoLog Locator (https://webapps.usgs.gov/GeoLogLocator/#!/) and provided here in the digitized form (shapefiles and feature classes), which were used in the generation of the hydrogeologic framework.
