16. Abstracts Intense rainfall associated with Tropical Storm Agnes in late June resulted
in the worst flood damage in the history of New York State. Flooding that began in
Westchester County on June 19 was followed by widespread flooding in the Southern Tier
and Finger Lakes regions on June 23.
Maximum known peak discharges were measured at three major rivers in the
State. The Allegheny River crested at the highest discharge of record on June 23
(73,000 cubic feet per second or 2,070 cubic metres per second). The Chemung River
at Chemung reached the highest discharge of record on June 24 (189,000 cubic feet
per second or 5,350 cubic metres per second). The Genesee River raised the water
at Mount Morris Dam to the highest level of record (755.8 feet or 230.4 metres).
Flooding associated with Tropical Storm Agnes caused 24 deaths and evacua
tion of 100,000 residents. Damage to· private property in the State has been estimated
at more than $400 mill ion; to public property, $221 million; and to agriculture $84
mi 11 ion.
