In the event the level rises above 592 feet above sea level there is a 200 foot wide spillway located one mile west of the dam which allows the runoff to flow to Lake Hamilton via Owl Creek.

This has never happened since the gates to the dam were closed in 1953.
 During the record high level of December 1982 the water was only 9.6 inches short of going over the spillway.
