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. Although this has never happened since the
gates to the dam were closed in 1953, there was a point during December 1982 -
January 1983 in which the water was only 9.6 inches short of going over the
spillway.
