Flood inundation map geospatial datasets for Lake Ontario, New York

Metadata Updated: October 28, 2023

Static flood inundation boundary extents were created along the entire shoreline of Lake Ontario in Cayuga, Jefferson, Monroe, Niagara, Orleans, Oswego, and Wayne Counties in New York by using recently acquired (2007, 2010, 2014, and 2017) light detection and ranging (lidar) data. The flood inundation maps, accessible through the USGS Flood Inundation Mapping Program website at https://www.usgs.gov/mission-areas/water-resources/science/flood-inundation-mapping-fim-program, depict estimates of the areal extent and water depth of shoreline flooding in 8 segments corresponding to adjacent water-surface elevations (stages) at 8 USGS lake gages on Lake Ontario. This item includes data sets for segment A - Lake Ontario (Thirtymile point) at Golden Hill State Park, NY (station number 04219796). These datasets demonstrate the estimated extent and depth of lake flooding at specific water levels of 1-foot increments from 247.0 ft to 251.0 ft (International Great Lakes Datum of 1985). In this study, wind and seiche effects were not represented; therefore, the flood inundation maps reflect five stages for Lake Ontario that are static for the entire shoreline area of the lake. In this study, wind and seiche effects were not represented; therefore, the flood-inundation maps reflect five stages for Lake Ontario that are static for the entire shoreline area of the lake. This item is a package of flood inundation data for segment A - Lake Ontario (Thirtymile point) at Golden Hill State Park, NY (station number 04219796) including: 1) 1 shapefile showing 5 estimated flood extents as polygons, 2) 5 raster datasets showing the depth of the water at 5 flood stages, 3) 1 shapefile showing the study limit extent of segment A, and 4) a metadata file. The polygon flood extent shapefiles were developed from digital elevation models (DEMs) derived from the lidar to represent the estimated areal extent for five flood stages for segment A. The raster files depict the depth, in feet (referenced to the International Great Lakes Datum of 1985), of the water in the inundated areas along the shoreline of Lake Ontario during the five theoretical flood stages. The depth grids were created by subtracting the digital elevation model (DEM) values (in feet) from each of five raster files representing the flood extent at each constant water level (in feet). An approximately 100-meter buffer was used as the extent into the lake.
