Navigation Notice

The Army Corps of Engineers M/V Ted Cook and crane barge crew have removed high spots from the shoaling near NM 9.7 - NM 9.8.  A partial width channel is available for transiting the area; no passing is advised within this reach.  From NM 9.5, vessels are advised to favor the red side along the long wall to the downstream approach to Lock 1.  Mariners are also advised to minimize their speed while transiting this area.

Based on the results from yesterday’s additional reconnaissance surveys from NM 9.3 downstream to Montgomery Point L&D, the following sailing instructions have been developed:

  -Montgomery Point L&D – NM 2: Stay 75’ off the red side

  -NM 3.4: Green Buoy is missing - favor the red side.

  -NM 6.0: Red Buoy is missing - stay towards the green side.

  -NM 7.2: Green Buoy is missing - favor the red side.

  -NM 8.7 – NM 8.9: Green Buoy is missing - stay in mid channel.

Updates will be provided as additional information becomes available.
