- Description:
Update: 4.0 MLLW as of 9/19/2023 on the Bob423 track.
Load the latest Bob423 track for 4.0 MLLW to see the way around the 0.4 MLLW shoal. The 10/17/2023 USACE survey is shown in the photos.First, the overview photo of the Isle of Palms
The approach to Isle of Palms from the north at MM 460.4 is shown below. Follow the Bob423 track to avoid the 0.4 MLLW shoal on the red side of the channel. The Bob423 track turns to avoid the many shoals here. You have to go outside the channel to find deeper water but then it's only deep to 4 MLLW. There are no plans yet to dredge Isle of Palms in 2024.
Another option is to take the “detour” route and avoid the 0.4 MLLW shoal entirely by following the red dotted line in the photo for 6.6 MLLW. It can be downloaded at the site link shown.

The final shoal before the Ben Sawyer Swing Bridge (going south) at MM 461.5 is shown. In this case, the best path is right in the middle of the channel for 7.1MLLW as of 10/17/2023
