Dataset contains a digital elevation model (DEM) of reservoir bathymetry and shoreline topography up to the dam crest elevation for the Calaveras Reservoir, located in Santa Clara and Alameda counties, California. Multibeam sonar, terrestrial lidar, and small uncrewed aircraft systems (sUAS) data were collected using methodology described in detail in a previous report of a similar reservoir survey project for the cooperator at a separate reservoir: Marineau, M.D., Wright, S.A, and Lopez, J.V., 2020, Storage capacity and sedimentation characteristics of the San Antonio Reservoir, California, 2018: U.S. Geological Survey Scientific Investigations Report 2019–5151, 34 p., https://doi.org/10.3133/sir20195151 The multibeam and sUAS datasets were combined with 2020 lidar data from the United States Geological Survey 3D Elevation Program (USGS 3DEP) to create the final DEM. Areas outside of the dam crest elevation contour were removed. Data is presented in GRID raster file formats.
