Beaver dams can help streams connect to their floodplains. These floodplain connections can expand the range of available aquatic habitats and aid in the restoration of stream and floodplain processes. North American beavers (Castor canadensis) occupy a wide variety of aquatic habitats; however, their ability to build dams, the agent of stream and floodplain change, is constrained in...

Beaver dams affect stream hydraulics by temporarily impounding water in stream channels. Beaver dams and their associated impoundments can potentially influence streamflow hydrographs and stream hydraulics in multiple ways including altering the magnitude and duration of high flows, temporary storage of storm water, and the range and spatial distribution of water depths and velocities in...

The California Groundwater Ambient Monitoring and Assessment Program Priority Basin Project (GAMA-PBP) analyzed per-and polyfluoroalkyl substances (PFAS) in groundwater samples collected from domestic and public drinking water supply wells in California. GAMA-PBP is a cooperative program between the U.S. Geological Survey and the California State Water Resources Control Board. This...

The U.S. Geological Survey (USGS), in cooperation with the New Mexico Department of Transportation, estimated the magnitude and frequency of floods corresponding to the 50-, 20-, 10-, 4-, 2-, 1-, 0.5-, and 0.2-percent annual exceedance probabilities (AEPs; otherwise known as the 2-, 5-, 10-, 25-, 50-, 100-, 200-, and 500-year floods, respectively) for 346 selected streamgages in New...

This data release provides phytoplankton identification and enumeration data during an algal bloom at Ash River boat docks on Kabetogama Lake (USGS site ID 482603092511801) collected between September 12 and September 13, 2023. samples were collected every three hours over a 24-hour period at two sites, one at the end of a dock and one on the adjacent shoreline. Two quality assurance...

This data release provides phytoplankton and fish environmental DNA (eDNA) and cyanotoxin biosynthesis gene abundance data from an algal bloom at Ash River Boat Docks on Kabetogama Lake (USGS site ID 482603092511801) collected between September 12 and September 13, 2023. Algal bloom samples were collected every three hours over a 24-hour period at two sites, one at the end of a dock and...

This data release provides cyanobacteria identification and enumeration data at Ash River Boat Docks on Kabetogama Lake (USGS site ID 482603092511801) collected in 2022. Sixteen environmental samples and four quality assurance replicates were collected from two locations, one at the end of the dock and one at the shoreline, between September 21, 2022 and September 22, 2022.

Airborne electromagnetic (EM) and magnetic survey data were collected by GeoTerrex Ltd. in the Upper San Pedro Basin and Fort Huachuca, Arizona in 1997 and 1999. EM data were collected using a time-domain GEOTEM system towed behind a fixed-wing aircraft with 30Hz cycle rate, 696,000 Am2 dipole moment, and 4 ms pulse width. Magnetic data were collected using a CS-2 cesium vapor...

These data contain located day-roosts for the northern long-eared bat (Myotis septentrionalis) at the North River Game Land, North Carolina in May and June of 2019. Data contained include individual bat tracked, date day-roost was found, day-roost unique ID, geographic coordinates of day-roost, tree species of day-roost, diameter breast height (cm) of day-roost, day-roost decay-stage...

Aerial imagery was collected with an uncrewed aerial system (UAS) and ground control points were used to construct a digital elevation model (DEM) and orthomosaic image using Structure-from-motion (SfM) photogrammetry for the Zuni Salt Lake in west-central New Mexico. The DEM and bathymetry survey points were combined to estimate lake water volume as a function of lake stage in the U.S...

To support the development of more accurate hurricane coastal impact models, we created a dataset containing an inventory of information sources of hard shoreline structures — including seawalls, groins, bulkheads, and breakwaters — for each U.S. state along the Gulf of America and Atlantic coasts. The shoreline structure inventory was developed initially from internet searches of open...

The U.S. Army Engineer Research and Development Center, in collaboration with the U.S. Geological Survey Wetland and Aquatic Research Center, collected hydrographic data to investigate sediment exchange between a back barrier marsh and open embayment through a tidal creek near Avalon, NJ, between July 2021 and August 2022. Data collected include time-series measurements of current...
