Extreme flooding on Lake Ontario can result in millions of dollars in damages to shoreline properties. Currently, USGS Lake Ontario gages report elevations around 247.8 ft above International Great Lakes Datum of 1985; a foot below record flood elevations observed in 2017. During 2017, wind-driven waves pounded the shoreline, causing widespread damage to infrastructure, homes, and businesses.

The President issued a “Major Disaster Declaration” for New York State as a result of damages caused by flooding along Lake Ontario (November 14, 2017).  United States Geological Survey lake elevation gages provide timely information to the NWS, emergency managers, and public during extreme conditions, and help describe coastal erosion processes.
