Harvey Locks Expected to Re-Open 0600 Monday 16 Oct 23

Mariners are advised that the Harvey Locks expected to re-open for Navigation at 6:00 A.M. Monday, 16 October 2023, due to forecasted weather that should allow for favorable locking conditions.

The parameters listed below are the safety measures we are proposing as we look forward to moving vessel traffic with an abundance of caution.

During the Mississippi River low water conditions Harvey Lock will have additional operating procedures and restrictions for daylight operations.

When positive head conditions are under 1.5 feet, tows will be restricted to 300’ in length including barge and boat. Additionally, there will be no breakouts allowed and no tows 70’ wide will be locked through.

USACE will request that USCG VTS mandates slow bell on ships passing Harvey Lock. USACE will cancel the slow bell request once the river has a head condition over 2 feet and resume normal lock operations.

During periods when deep draft ships are passing and positive head conditions are between 1.5 feet and 2 feet, we will keep both sets of gates closed with the water level in the chamber level equal with the Harvey Canal.

Once the Mississippi River stage drops below one foot of positive head, we will chain the river end gates as we keep operating .

Once the Mississippi River stage drops to 6 tenths of a foot of positive head, this will trigger the lock closing.

We request that all mariners lock with extreme caution. For questions, please contact the head lock operator on duty at 504-366-5187.

USACE would like to thank our customers for being diligent to ensure that we provide safe and excellent lock operations during this period of low water on the Mississippi River.
