Data

Conodonts were collected in the southern Lake Champlain valley to aid in identifying lithostratigraphic units, determining biostratigraphic zonations, and correlating to other regions. The conodonts were identified by experts in Cambrian and Ordovician micropaleontology. Microslides/thin sections were made of different lithostraphigraphic units of the southern Lake Champlain valley to...

In this study we are deploying several sensor arrays within a small stream channel, the Rio De Las Vacas, in the Jemez mountains of Northern New Mexico in coordination with a local partner, who are implementing several low-tech process based restorative practices including Beaver Dam Analogs (BDAs). This cooperation has allowed us to build a hydrological picture before and after the...

Fish are often used as bioindicators to test the state of their environment qualitatively or quantitatively. This data set contains details of lake sturgeon (captured in the Genesee and Oswegatchie Rivers for Bioindicator Project GL-00E00825-0, 2012-2013). This study focused on non-lethal comparison of chemicals in age matched release juvenile lake sturgeon in an Area of Concern...

Lake Erie historically supported a large population of Cisco (Coregonus artedi) which provided an important fisheries resource. The Cisco population declined precipitously in the 1920s and by the 1960s the species was considered extirpated from the lake. In May of 2025, the New York State Department of Environmental Conservation experimentally released age-1 Cisco into Lake Erie to...

The U.S. Geological Survey (USGS) 3D Elevation Program (3DEP) has developed an integrated 1-meter topobathymetric digital elevation model (TBDEM) for the Potomac River extending from tidal Washington, D.C. to upstream of Hancock, Maryland. This is the third 3DEP pilot inland TBDEM, developed to produce a 3-dimensional surface elevation model that integrates topographic bare-earth...

The U.S. Geological Survey (USGS), in cooperation with the Nebraska Department of Transportation, initiated a flow-frequency study for the Elkhorn River basin in Nebraska for flow data for water years 1881-2022. Estimates of the magnitudes of peak flow were determined using the USGS PeakFQ flood-frequency program, version 7.5.1 at the 50, 20, 10, 4, 2, 1, 0.5, and 0.2 percent chance...

This dataset describes tissue samples derived from Phragmites leaves spanning a developmental gradient from the youngest fully-expanded leaves to senescing leaves, as well as freshly senesced and partially decomposed leaf litter. Sample information includes leaf category, broad and local scale environmental descriptors, the geographic name and location of collection sites, and National...

A bathymetric dataset was collected on September 7, 2022, of Lost Lake (reservoir) located in the Modoc National Forest, California. Both bathymetric and terrestrial lidar (light detection and ranging) data were collected via a boat-based multibeam echosounder and lidar scanner to compute a digital elevation map (DEM) of the lakebed and the near shore. The DEM was used to provide an...

To understand water scarcity issues in the Upper Colorado River Basin (UCRB), our research team collaborated with librarians at the Department of Interior with access to Lexis Nexis to query its newspaper and congressional research databases for topics of interest between 2000 and 2024 in our area of interest in the UCRB. The data were pre-processed into a tabular format and loaded into...

Aerial photography surveys of Redoubt Volcano in Lake Clark National Park, Alaska, were conducted on August 8 and September 26, 2019, by fixed-wing aircraft to generate updated elevation data and high-quality orthoimagery. The surveys were flown by the National Park Service (NPS) Alaska Regional Office (AKRO) in partnership with the United States Geological Survey (USGS) Alaska Volcano...

The data were collected as part of a study using underwater cameras to describe fish habitat preferences under the ice in four backwaters located in Pools 7 and 8 on the Upper Mississippi River. The dataset contains both environmental data and fish abundance data. The environmental data were collected at each site to describe the conditions and water quality at the time of sampling. The...

The Great Lakes Fishery Commission sea lamprey program is concerned with the risk of lampricide applications to non-target animals, especially those of conservation concern. Conneaut Creek (Ohio and Pennsylvania) is routinely treated for larval sea lampreys (Petromyzon marinus) and contains a population of salamander mussels, which has been proposed for listing as federally endangered by...
