On August 25, 2020, the U.S. Geological Survey conducted a bathymetry survey of a 550 meter long reach of the Black River near Great Bend, New York. The study reach began approximately 1,000 meters upstream from the State Route 26 bridge in Great Bend, New York. Depth data were collected primarily with a 1,200 kilohertz Teledyne RD Instruments RioPro acoustic Doppler current profiler (ADCP) with position data from differential global navigation satellite system (GNSS) Hemisphere V102 DGPS antenna (any use of trade, firm, or product names is for descriptive purposes only and does not imply endorsement by the U.S. Government). Water surface elevations were established using real-time kinematic (RTK) GNSS surveys;...

This dataset contains inundation boundary polygons for 15 modeled water-surface profiles at 5 flood frequencies (50- , 10- , 2- , 1- , and 0.2-percent annual exceedance probabilities, or 2- , 10- , 50- , 100- , and 500-year recurrence intervals) and 3 lake levels (representing average conditions, a 2-year-high condition, and a 100-year-high condition).
