Around the Region

The condition of the two workers was not immediately clear. They were there doing core sample drilling at the time of the blast.

MAYES COUNTY, Okla. (AP) — The Grand River Dam Authority says two men were killed and a third person was injured in an explosion in a northeastern Oklahoma dam where they were doing maintenance work.

GRDA Vice President John Wiscaver says the bodies of two contractors were recovered early Friday from inside Kerr Dam near Locust Grove, about 45 miles east of Tulsa.

GRDA spokesperson Justin Alberty says a third contractor escaped and that the dam was not damaged by the explosion about 6 p.m. Thursday.

The cause of the blast was not immediately known. The GRDA operates dams to generate electricity for customers that include cities in Kansas and Oklahoma.

The contractors were about 80 feet down from the top of the dam and doing routine core sample drilling when they were trapped, Alberty said.

“Right now the priority is to get to them, to get down to those two individuals,” Alberty said.
