WY 2024–Topobathymetric elevation model of the causeway breach, Great Salt Lake, Utah
This section of the data release includes the topobathymetric elevation dataset representative of topography during the 2024 water year for the causeway breach of Great Salt Lake. Surface and shallow topography were surveyed by drone photogrammetry on October 19, 2023 and ADCP bathymetry on August 14, 2024. At its lowest point across the breach, the management berm eroded from the as-built elevation of 4,192 feet above the National Geodetic Vertical Datum of 1929 to approximately 4,187 feet between its construction on February 10, 2023, and October 19, 2023. The vertical error subaerial topography is less than one centimeter (cm); for submerged regions across the berm only, the median error estimate is 2.99 cm. The dataset includes an assimilated raster comprising interpolated bathymetry from ADCP survey points and a photogrammetric digital elevation model, a spatial metadata shapefile that defines the data sources for the raster, tabular data of the source acoustic Doppler current profiler (ADCP) bathymetry, and tabular data of the real-time kinematic (RTK) elevation data that was used for corrections in the photogrammetric digital elevation model. The topobathymetric dataset was generated with a horizontal projection of UTM Zone 12N, North American Datum of 1983, Geoid 18 at a 0.5-meter horizontal resolution, and referenced to the North American Vertical Datum of 1988 in feet.
