The City of Flagstaff in northern Arizona utilizes Upper Lake Mary reservoir for approximately 25 to 30 percent of its water supply and understanding the detailed topography of the storage basin is essential for effective water management. The U.S. Geological Survey incorporated modern bathymetric and ground survey techniques to construct a 1-meter (1m) resolution digital elevation model...

The Pacific Northwest is home to numerous faults that cut through the surrounding crust including the Seattle fault. Over time, frictional stresses accumulate along these faults, building slowly until they exceed the fault's strength, resulting in an earthquake. Evidence of these earthquakes may be found in Pacific Northwest lakes. Past underwater landslides caused by the earthquakes...

These data are high-resolution bathymetry (riverbed elevation) and depth-averaged velocities in comma-delimited table format, generated from hydrographic and velocimetric surveys near highway bridge structures over the Missouri River in Kansas City, Missouri, on August 8–9, 2023. Hydrographic data were collected using a high-resolution multibeam echosounder mapping system (MBMS), which...

In 2025, the U.S. Geological Survey (USGS), in collaboration with the Cook County Bureau of Technology (BOT), carried out comprehensive hydrographic and water-quality surveys, and activity and disturbance assessments of 34 total water bodies within Cook County, Illinois. These surveys and assessments describe the bathymetry, water-quality conditions, and on-site field crew observations...

Two dams on the Elwha River, Washington State, USA trapped over 20 million m3 of sediment, reducing downstream sediment fluxes and contributing to erosion of the river's coastal delta. The removal of the Elwha and Glines Canyon dams between 2011 and 2014 induced massive increases in river sediment supply and provided an unprecedented opportunity to examine the response of a delta system...

This dataset, prepared by the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC), provides beach profile data collected at Dorado, Puerto Rico. Data were collected from 2022-2024 on foot by a person equipped with a Global Navigation Satellite System (GNSS) receiver and antenna affixed to a backpack outfitted for surveying location and elevation data...

This dataset, prepared by the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC), provides beach profile data collected at Isla Verde, Puerto Rico. Data were collected from 2022-2024 on foot by a person equipped with a Global Navigation Satellite System (GNSS) receiver and antenna affixed to a backpack outfitted for surveying location and elevation...

This data release presents geologic map data for the bedrock geology of the Aztec 1-degree by 2-degree quadrangle, New Mexico. Geologic mapping incorporates new interpretive contributions and compilation from published geologic map data sources primarily ranging from 1:24,000 to 1:50,000 scale. Much of the geology incorporated from published geologic maps is adjusted based on digital...

The data are a curated set of 200k records of bees, both native and introduced, that were collected from 2002 – Present throughout the state of Maryland and the District of Columbia. Collection methods, habitats, and duration of studies ranged depending on project.

This data set includes information on benthic algae community composition collected during the growing season of 2024 at stations located along the U.S. shoreline of Lakes Michigan, Huron, Erie, and Ontario. Benthic algal community observations were taken by scuba divers in the field and by personnel in the lab during sample processing, including detailed microscopic examination of...

This dataset includes information collected before and after a 2023 copper treatment was implemented by the State of Idaho to eradicate invasive quagga mussels in the Snake River, Idaho. Water, sediment, periphyton, and macroinvertebrates were sampled at Snake River sites upstream, within, and downstream of the copper treatment reach in order to evaluate the fate and transport of the...

This shapefile contains habitat polygons identifying the dominant and major geomorphological structure, biological type and percent cover, and geologic zone for 11 square kilometers of Olowalu reef off west-central Maui at a minimum mapping unit of 100 square meters. Habitats were mapped with heads-up digitization using the NOAA Habitat Digitizer Extension in ArcMap (Esri, v.10.8.2)...
