Official Army Corps of Engineers Survey (as of November, 2012) of AICW Problem Stretch North of Charleston SC Harbor (near St. M. 460)
Posted by Claiborne | Posted on 11-14-2012
We are pleased and honored to report that the Salty Southeast Cruisers’ Net has dedicated friends at the various Army Corps of Engineers Headquarters who work hard to keep the cruising community informed about newly developing problems on the AICW. And, that is just what Captain Mike Verdolini has done by forwarding the official November, 2012 AICW depth survey pictured below.
Take a gander at the NOAA chartlet to the right, and you will quickly see that the survey in question centers on the Waterway, north of Charleston Harbor and the Ben Sawyer Bridge, between Inlet Creek’s northeastern mouth and Swinton Creek.
Take a look at the image below, and study the recorded, MLLW corrected soundings along the AICW’s southern/southeastern flank, between Inlet Creek’s northeastern mouth and Swinton Creek. Look at those 0.8, 1.1 and 2.5 foot (etc.) soundings. Think the Waterway may have a shoaling problem here?
Also, notice that this thin water along the AICW’s southern flank continues to a point well east and northeast of marker #117A!
For at least a year now, we have had these water designated as an SSECN Navigation Alert. Now, however, with this official USACOE information in hand, we are going to upgrade the difficulty of these waters to an “AICW Problem Stretch.”
ALL cruisers should proceed with the greatest caution through this section of the Waterway, preferably at mid to high tide, and favor the northern side of the channel somewhat.
WE ARE SEEKING INPUT FROM THE CRUISING COMMUNITY CONCERNING THIS NEW AICW PROBLEM STRETCH! If you have traversed these waters recently, PLEASE send us your soundings and impressions. You can simply follow the “Click Here to Submit Cruising News” button/link found on the upper right of this and all (except Chart View) SSECN pages, or send your data directly to CruiserNet@triad.twcbc.com.
