Notice to Navigators: Upper Mississippi River

RIAC Navigation Notice 22-01 Melvin Price Main Lock Chamber
Closed Until Further Notice 19 Jan 2022


Not good news.

The aux chamber is available though. USACE is moving some equipment out of the aux now so they can lock tows.

The Prairie Dawn is already at the lock light boat so he will pull SB cuts at the aux chamber to get some traffic moving. As more boats show up, we should be able to keep traffic moving with industry help pulling cuts.
