Is Cayuga Lake full?

Cayuga Lake is a natural lake, so it has no full pool. The New York State Canal Corporation regulates its outlet at Mud Lock, but there is no set top level; the page compares the level with past years and with the National Weather Service flood stage at Ithaca (383.5 ft). It is 0.12 ft lower than a year ago (382.05 ft on Nov 8, 2025).
