TULSA, Okla. (AP) — The U.S. Army Corps of Engineers in Tulsa has requested to raise the water level at Webbers Falls to 491.5 feet (149.81 meters) for 24 hours to help free two sunken barges.

The request made Wednesday with Southwestern Division Headquarters continues the efforts to recover two sunken barges at Webbers Falls. The pool reached 491 feet (149.66 meters) Tuesday morning.

Flooding caused two barges to break from constraints and crash into a lock and dam in May, preventing three gates from closing. Water flow at the gates is now estimated at 55,000 cubic feet (1557.6 cubic meters)...
