City staff members were working on winter preparations and lake level calibrations Thursday when the north bascule gate stopped operating, according to a statement issued by Interim City Manager Billy Tyus. Water began rapidly flowing out of the lake.
Other gates have been adjusted to reduce the amount of water flowing out of the lake, but city staff expect the lake to be 4 feet lower, or 610 feet above sea level, by Friday. Tyus said city staff would have a better idea of the needed repairs Friday, after water has stopped flowing over the malfunctioning gate.
Downstream landowners and Archer Daniels Midland Co. officials have been notified about the increased river flow, Tyus said. ADM operates its own water treatment facility connected to Lake Decatur.
