MANHATTAN, Kansas (AP) – The U.S. Army Corps of Engineers has reduced flows from Tuttle Creek Lake since a 15-foot sinkhole was found near the lake.
The Manhattan Mercury reports the sinkhole on the east side of outflow tubes at Tuttle Creek Lake measures 15 feet in diameter and 8 feet deep.
Engineers reduced outflows from the lake from 19,000 cubic feet per second to 6,200 when they noticed the hole forming last week. They also closed the gates on the east side of the lake’s dam. They have since increased outflows.
Brian McNulty, operations manager for Corps of Engineers, says the sinkhole likely formed as a result of recent high water levels and outflows from the lake and doesn’t indicate any structural problems in the dam.
