Geospatial dataset of bathymetric survey of the Cayuga Inlet flood-control channel and selected tributaries in Ithaca, New York, 2016

September 20, 2017

From July 14-20, 2016, the U.S. Geological Survey, in cooperation with the City of Ithaca, New York, conducted a bathymetric survey of the Cayuga Inlet flood-control channel and selected mouths of tributaries to Cayuga Inlet and Cayuga Lake in Ithaca, New York. U.S. Geological Survey personnel collected bathymetric data using an acoustic Doppler current profiler. The survey plan produced a dense dataset of water depths that were converted to bottom elevations by subtracting the depths from the water-surface elevations recorded by the USGS Cayuga Lake gage, which was located within the surveyed reach. These elevations were then used to generate a geographic-information-system bathymetric surface.
