Arkansas River Lock To Close In August

The Arkansas River will experience a scheduled 10-day complete lock closure during August.  David Terry Lock (Lock No. 6) at Mile 108 will be closed August 19 through August 29. Those closure dates were adjusted on July 10 in a Navigation Notice. The purpose of the closure is to allow Corps personnel to perform pull tests on the center post receivers. Due to some unknowns associated with the tests, the Corps cautions that further adjustments in the schedule may be required.

There is no auxiliary chamber available at David Terry Lock.

The Joe Hardin Lock (No. 3) was originally scheduled to be closed in early August, but that closure has been postponed until further notice.

Questions or requests for additional information concerning this notice may be directed to the Little Rock Engineer District at 501-324-5739 or via email at: CESWL-OP-OM@usace.army.mil.
