Data

These data are the survey results from a five-mile section of the Platte River at, and upstream of the Nebraska Army National Guard Camp Ashland Training Site including the side channel chutes on the east bank. All survey data were collected along planned transect lines that were spaced 492.125 US survey feet apart beginning near the mouth of the Elkhorn River and ending near the U.S...

The U.S. Geological Survey, in cooperation with the City of South Padre Island, Texas, collected baseline bathymetric data for a near-shore area of the Laguna Madre near South Padre Island in July 2021. Bathymetric survey points were collected using real-time kinematic Global Navigation Satellite System (RTK-GNSS) equipment. The data included in this data release are presented in a comma...

As part of the Great Lakes Restoration Initiative (GLRI) project template 774-18 entitled "Development of monitoring and response methodologies, and implementation of an Adaptive Management Framework to work towards Eradication of Grass Carp in Lake Erie" an integrated bathymetric/hydrodynamic/water-quality survey of the Maumee River (Ohio) was completed by the U.S. Geological Survey...

This bathymetric dataset provides an update to the stage-storage relation for Quail Lake (reservoir) located in the El Dorado National Forest, Calif. Bathymetric data was collected using a multibeam echo sounder to provide near-complete coverage and was merged with USGS 3DEP lidar to compute a DEM of the lake and near shore. The DEM was used to computed storage and surface area for a...

In 2008, the U.S. Geological Survey began mapping the main channel and shallow intertidal mudflats between the Dumbarton Bridge and a railroad bridge located 1 km to the south in south San Francisco Bay. This information was collected to document bathymetric change before and after restoration to inform the South Bay Salt Pond Restoration Project (https://www.southbayrestoration.org)...

In 2010, the U.S. Environmental Protection Agency, Region 10, initiated the Puget Sound Scientific Studies and Technical Investigations Assistance Program, which was designed to support research for implementing the Puget Sound Action Agenda. The Action Agenda was created because Puget Sound was designated as one of 28 estuaries of National Significance under section 320 of the Clean...

The surveys were conducted to map surficial geology and benthic habitat as part of the USGS California Seafloor Mapping Program, a collaboration with California State University Monterey Bay (CSUMB) and the National Oceanic and Atmospheric Administration (NOAA). These data are intended to provide regional bathymetric information in California State waters for offshore resource and...

Surveys offshore of Point Buchon, California, were conducted to map surficial geology and benthic habitat as part of the USGS California Seafloor Mapping Program, a collaboration with California State University Monterey Bay (CSUMB) and the National Oceanic and Atmospheric Administration (NOAA). These data are intended to provide regional bathymetric information in California State...

Surveys offshore of Point Estero, California, were conducted to map surficial geology and benthic habitat as part of the USGS California Seafloor Mapping Program, a collaboration with California State University Monterey Bay (CSUMB) and the National Oceanic and Atmospheric Administration (NOAA). These data are intended to provide regional bathymetric information in California State...

Dataset contains reservoir bathymetry and shoreline topography up to dam crest elevation. Data were collected using small uncrewed aerial system (sUAS), multibeam sonar, and terrestrial lidar. Version 2.0 The multibeam sonar & terrestrial lidar data in version 2 was reprocessed for higher accuracy. 1-meter lidar data for 2020 from the USGS 3DEP program was used around the shoreline of...

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...
