- All navigation interests are advised that the Jerry Costello Lock and Dam closed at 22:00 hours on Sunday 27 December 2015, due to high river stages.
- This closure is necessary due to water levels exceeding elevation 380.5 NGVD. At that elevation, water enters the Miter Gate machinery recesses and prevents movement of the miter gates. The Lock will remain closed until water recedes below elevation 380.5 NGVD, and any necessary cleanup operations are completed.
- All navigation interests should be alert for, and abide by, any special instructions that may be issued by the Lockmaster.
