Map showing flood of June 1972 resulting from tropical storm Agnes, Bald Eagle and Fishing Creeks at Mill Hall, Pennsylvania
In June 1972, tropical storm Agnes caused severe flooding in Pennsylvania and southern New York. The floods 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 central Pennsylvania, large areas in Lock Haven, Mill Hall, Wilkes-Barre, Kingston, Pittston, Harrisburg, and in many smaller communities were inundated to depths of several feet. The extent of flooding shown on the map was delineated by the U.S. Geological Survey from field surveys made soon after the flood.
