Gaynor Lake drainage issue fixed after lake was called 'potentially unstable'

LONGMONT, Colo. - Gaynor Lake, near Longmont, is once again safe after a drainage problem caused the state's chief of dam safety to call it "potentially unstable."

Bill McCormick, Colorado's chief of dam safety, told CALL7 Producer Michael de Yoanna that a failure of the dam would pose a "significant hazard."

"The reservoir must be drained immediately," McCormick said, adding that efforts are underway.

The situation had changed significantly within an hour, however, as crews cleared the problematic drainage ditches.

The lake is located on Oxford Road and U.S. 287.
