From 2013 to 2015, bathymetric surveys of New York City’s six West of Hudson reservoirs (Ashokan, Cannonsville, Neversink, Pepacton, Rondout, and Schoharie) were performed to provide updated capacity tables and bathymetric maps. Depths were surveyed with a single-beam echo sounder and real-time kinematic global positioning system (RTK-GPS) along planned transects at predetermined intervals for each reservoir. A separate set of echo sounder data was collected along transects at oblique angles to the main transects for accuracy assessment. Field survey data was combined with water-surface elevations in a geographic information system to create three-dimensional surfaces representing reservoir-bed elevations in the...

These data were collected using a 600 kHz Rio Grande ADCP (acoustic Doppler current profiler) in mode 12 from a moving boat. The data were georeferenced with a Hemisphere A101 Smart Antenna differential GPS. These data were processed with Teledyne RD Instruments' software, WinRiver II. These data were collected concurrently with several water quality parameters that were collected by an autonomous underwater vehicle (AUV) in the same reach. This data release supports the following publication: VonIns, B.L., and Jackson, P.R., 2017, Response of currents and water quality to changes in dam operations in Hoover Reservoir, Columbus, Ohio, August 24–28, 2015: U.S. Geological Survey Scientific Investigations Report 2017–5027,...
