This dataset contains raster grids of water surface elevation 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).

Water depths were measured during November 2015 and bathymetric elevations were computed for the lower Sixmile Creek reservoir in Ithaca, Tompkins County, N.Y. These data were used to create a bathymetric surface (TIN) of the reservoir. Data collected in 1938 were used to create a second TIN and a contour line shapefile. This dataset includes the ADCP-measured transect data and manually-measured point data collected by the U.S. Geological Survey, Ithaca, N.Y., during November 16-20, 2015, and the two bathymetric-surface TINS (for 1938 and 2015) and a 1938 contour line shapefile that were created by the GIS program, City of Ithaca, N.Y.

USGS Science Data Catalog (SDC),
Digital flood-inundation maps for a 2.9-square-mile area of Ithaca, New York, were created in 2015–18 by the U.S. Geological Survey in cooperation with the City of Ithaca, New York, and the New York State Department of State. The flood-inundation maps depict estimates of the maximum areal extent and depth of flooding corresponding to selected flood frequencies for Cayuga Inlet, Sixmile Creek, Cascadilla Creek, and Fall Creek and selected water-surface elevations of Cayuga Lake. Flood profiles for the stream reaches were computed by combining a one-dimensional step-backwater model for the stream channels and a two-dimensional model for the overbank areas. The resulting hydraulic model was calibrated by using water-surface...

Flood profiles for the stream reaches were computed by combining a one-dimensional step-backwater model for the stream channels and a two-dimensional model for the overbank areas. The resulting hydraulic model was calibrated by using water-surface profiles from five observed storm events. The model was then used to compute 15 water-surface profiles for 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). The geographic information system flood-extent polygons, depth grids, and water surface elevation grids...

bathymetry data,
Water depths for the lower Sixmile Creek reservoir in Ithaca, Tompkins County, N.Y. that were measured during 1938 were found in the files of the GIS Program, City of Ithaca. This agency computed bathymetric elevations and created a bathymetric surface (TIN) of the reservoir.

bathymetry data
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 generated over 25,000 water depths that were converted to bottom elevations by subtracting the depths from the water-surface elevations recorded by the USGS streamgage, Cayuga Inlet (Cayuga Lake) at Ithaca, N.Y. (station number 04233500), which was located within the surveyed reach. (Information on and data from this streamgage can be found...
