TULSA, Okla. -- Work involving the repair of a major component of a lock along the McClellan-Kerr Arkansas River Navigation System was recently completed ahead of schedule by the Tulsa District U.S. Army Corps of Engineers.
The work involved the removal and replacement of a pintal ball at Lock 17 at Chouteau, Okla., This was the first time such a repair has been performed to a lock on the MKARNS. The entire lock was emptied of water, an operation referred to as "dewatering," so that the dam gate could be lifted for the removal of the pintal.
