Shoal prone Stump Pass Inlet indents the western shores of the Western Florida ICW and Lemon Bay, well south of Venice, Florida, near Statute Mile 39.5. In spite of periodic dredging, this seaward cut seems to begin filling in by the time the dredge disappears over the horizon.
Below, Captain Archie Faulkner gives us a good look at the current navigational conditions on the Stump Pass channel, at least as of December, 2013. While this is very useful info, BE WARNED THAT CONDITIONS COULD BE VERY DIFFERENT BY THE TIME OF YOUR ARRIVAL, so PLEASE do NOT use this advice as your soul means of deciding whether to make use of this inlet, or in navigating the channel.
Personally, unless I am researching in a small craft, we NEVER use Stump Pass. Venice Pass, to the north, is a FAR more reliable passage! It’s your decision though, and your responsibility!

Stump Pass is shoaling on the north side. Unmarked red and green buoys mark the deepest cut. Daymarks 1 and 2 have only about 4 ft depth between markers. The natural cut runs SW from the outer nun buoy to the GOM and carries about 8 ft.

Some deep draft boats (5′ or so) have been negotiating Stump Pass. However the skipper should obtain local knowledge before even considering passage.
