Army Corps of Engineers releasing water from Tuttle Creek Lake

RILEY COUNTY, Kan. (KWCH/WIBW) The U.S. Army Corps of Engineers plans a major increase in the amount of water being released through Tuttle Creek Lake.

Starting Wednesday, approximately 112,249 gallons per second will be passing though the outlet works, also known as the tubes.

Even with the heavier outflow, experts expect the water will remain in the river channel. They don’t believe it will cause downstream flooding and are not issuing any evacuation orders. In fact, they are calling the move good news.

“This release will help slow down the rise of the lake. We’re definitely not out of the woods yet, but this release is a positive development for our community,” said Scott French, Manhattan Fire Chief and current Incident Commander.

A high water advisory has been issued for Tuttle Creek Lake and the surrounding areas. City officials say residents should prepare for potential high water that may impact homes, businesses, and nearby roads.

Emergency personnel with official identification cards will continue visiting households in flood prone areas to make people aware of the potential danger. They will ask for information about the number of people in the household, if occupants have flood insurance, and if anyone in the home has medical needs that would make evacuation difficult.

This information will allow emergency responders to prepare for safe evacuation and alert the American Red Cross to any special needs to help set up future shelters. No shelters are open at this time.
