To support the modeling of storm-induced flooding, the USGS Coastal National Elevation Database (CoNED) Applications Project has created an integrated 1-meter topobathymetric digital elevation model (TBDEM) for Puget Sound. Puget Sound is located along the northwestern coast of Washington and is part of the Salish Sea. Puget Sound is the third largest estuary in the United States. High-resolution coastal elevation data is required to identify flood, storm, and sea-level rise inundation hazard zones and other earth science applications, such as the development of sediment transport and storm surge models. The new TBDEM consists of the best available multi-source topographic and bathymetric elevation data for Puget...

This section of the data release includes the topobathymetric elevation dataset of Great Salt Lake as an assimilated raster comprising interpolated bathymetry from 2005 and 2006 (Baskin, 2005; Baskin, 2006) and QL1 and QL2 lidar from 2016 (Utah Geospatial Resource Center, 2016). The bathymetric dataset was originally published as contour maps. The contours were interpolated to develop a digital elevation model that is readable by a geographic information system and compatible with topographic lidar data generated in 2016. Because the water elevation of Great Salt Lake has declined since 2005, regions of the bathymetric and lidar datasets overlap to provide a reasonable estimate of error. The topobathymetric dataset...

In recent years, rising sea levels have threatened critical infrastructure and cultural assets at Puʻuhonua o Hōnaunau National Historical Park thus motivating the park to make adaptive decisions in managing these key resources. To support the development of decision support tools for sea level rise preparedness, the U.S. Geological Survey (USGS) Coastal National Elevation Database (CoNED) Applications Project has created an integrated 1-meter topobathymetric digital elevation model (TBDEM) for Puʻuhonua o Hōnaunau National Historical Park. This dataset was developed in collaboration with the University of Hawaii- Mānoa Sea Level Center, Department of Interior Pacific Island Climate Adaptation Science Center, and...

This section of the data release includes tables in the format of comma-separated value (CSV) files with elevation-area-volume relationships for Great Salt Lake. The volume and area of Great Salt Lake were calculated from the topobathymetric raster dataset, which was resampled from 0.5-meter to 5.0-meter resolution, at elevation increments of 0.01 feet between 4,170.00–4,215.00 ft above the North American Vertical Datum of 1988. Data are provided as total values for Great Salt Lake as well as regional values for the north arm, south arm, Bear River Bay, and Farmington Bay.

This data release is associated with the following Scientific Investigations Report: Root, J.C. and Jones, D.K., 2022, Elevation-area-capacity relationships of Lake Powell in 2018 and estimated loss of storage capacity since 1963: U.S. Geological Survey Scientific Investigations Report 2022–5017, 21 p., https://doi.org/10.3133/sir20225017. This dataset provides elevation-area-capacity relationships for Lake Powell derived from a topobathymetric digital elevation model (TBDEM) that was collected in 2017 and 2018. The TBDEM was modified (Jones and Root, 2021, available for download at https://doi.org/10.5066/P9H60YCF) from the originally published version (Poppenga and others, 2020, available for download at https://doi.org/10.5066/P9XX0J1Y)...

To support the modeling of storm-induced flooding, the USGS Coastal National Elevation Database (CoNED) Applications Project has created an integrated 1-meter topobathymetric digital elevation model (TBDEM) for the Southern California Coast and Channel Islands. The Channel Islands are a chain of eight islands where years of isolation has created unique fauna, flora, and archeological resources. The archipelago extends for 160 miles (257 km) between San Miguel Island in the north and San Clemente Island in the south. Five of the islands are part of Channel Islands National Park (Anacapa, Santa Cruz, Santa Rosa, San Miguel, and Santa Barbara), and the waters surrounding these islands make up the Channel Islands National...

This dataset provides a modified version of the previously published Lake Powell topobathymetric digital elevation model (TBDEM; Poppenga and others, 2020). The original TBDEM is comprised of four source datasets: (1) a 2017 1-meter multibeam bathymetric survey; (2) a 2018 topographic light detection and ranging (lidar) derived digital elevation model (DEM); (3) a historical topographic DEM that was interpolated from contours maps created in 1947 and 1959; and (4) interpolated topography where gaps existed in the bathymetric and lidar data or where historical data were not suitable (Poppenga and others, 2020). For this data release, two corrections were made to the TBDEM to address errors associated with the historic...
