In June 1972, tropical storm Agnes caused sever flooding in Pennsylvania and southern New York. The flood, on many major streams were the highest known since the river valleys were settled. Maximum discharges were as much as twice the discharge of a 50-year flood. In southern New York, large areas in Corning, Elmire, Wellsville, Salamanca, and in many smaller communities were inundated to depths of several feet. Levels of all of the Finger Lakes were higher than any previously recorded, and extensive flooding of lakeside properties resulted.
The extent of flooding shown on the map was delineated by the U.S. Geological Survey from earlier photography and limited field survey.
The investigation was conducted in cooperation with the State of New York and the U.S. Army Corps of Engineers.
