Fields Cut is located in extreme southern South Carolina. The Wateway uses this man-made stream to connect between the Wright and Savannah Rivers.
Fields Cut is currently the worst stretch on the South Carolina portion of the AICW. That's why Captain Chris's report below is so very important.
Notice also Chris' reports on Ramshorn Creek and Walls Cut.

Claiborne,
Transited Field's Cut today.  We entered the cut at 1 hour before high tide.  At the south entrance, 50 feet west of the magenta line we had 12 feet — 3-4 feet at MLLW.  When we reached the floater #48 we had 12 feet on the magenta line. 
At Walls Cut we had 13.8 feet at high tide on the magenta line where it crosses the "9 foot" MLLW contour line. 
At the entrance to Ramshorn Creek our C-MAP NT chip shows the marks in incorrect positions.  Obeying the marks provided us 13.8 feet at High.  We would have hit the silt if we had obeyed the chartplotter.  Right before the powerlines in Ramshorn (going north) there is a small creek to the east.  It has dumped enough mud into Ramshorn that the depth rises to 12.5 feet before falling away to the Ahhhh of Cooper River. 
Also something very large has clobbered the bulkheads of the Hilton Head Bridge.   There is a work barge in the area so going through here slowly is a good idea.
