ITCS Memo # 2321

SPECIAL NOTICE TO NAVIGATION INTERESTS

Locks No. 27, Lower Mississippi River Mile 185.1

1. All navigation interests are advised that the St. Louis District is revising the closure schedule for the Auxiliary Lock Chamber at Locks 27, due to a slippage in delivery of lift gate machinery.

2. The new closure dates for the auxiliary lock chamber are from 0600 hours on
17 October 2005 until 0600 hours 13 December 2005. During the times that the auxiliary lock chamber is closed, the main lock chamber will remain open.

3. The second closure, of the main lock chamber, remains unchanged and will be from 0600 hours 3 January 2006 until 0600 hours 1 March 2006. As noted in the previous Navigation Notice dated 24 August 2005; during the times that the main lock chamber is closed, the auxiliary lock chamber will remain open. However, since the auxiliary lock is not equipped with tow haulage equipment, double lockage tows will have to arrange for pull boat assistance. The towing industry self help program of using waiting tow boats to assist in pulling cuts will be coordinated when the situation warrants.

4. All navigation interest should be alert for, and abide by, any special instructions that may be issued by the Lockmaster in conjunction with these closures.

Rivers Project Manager
