How much water there actually is — and six other things nobody else has
The big one. The Army Corps surveys these channels and publishes the controlling depth in a plain text file inside every survey. Nobody reads them. We now read all of them, every reach from Southport to Cape Lookout, and tell you what they found and how long ago they found it.
- ›CONTROLLING DEPTH — 55 reaches with a real surveyed depth. 49 of them are shallower than the depth they are supposed to be maintained at. Shown as a BAND, never a single decimal, because a survey is one day in water that moves — one reach here went from 7 ft to 3 ft in seventy days.
- ›Survey age sits next to every number, and past a year it refuses to compute at all rather than dress up something stale.
- ›It also tells you how much of each reach was actually surveyed. ‘1 ft, coverage 6’ means they found a foot and only looked at six per cent — the rest could be worse, not better. That is the opposite of how it reads at a glance.
- ›TIDAL CURRENT — which way the water is running, and what wind against an ebb is doing to it. Only 3 of our 9 inlets have a NOAA current station; the other six say so rather than borrowing a neighbour’s number. Masonboro is one of the six.
- ›BRIDGES — every span in the corridor, when it opens, and what it clears. Arrive at the Wrightsville bascule at 10:20 and it now tells you: 40 minute wait, next opening 11:00. The route planner adds that wait to your run.
- ›Two corrections worth knowing: the Grayden Paul bridge at Beaufort is gone, and Surf City has been a fixed 66 ft span since 2018. Federal regs were only updated this January and most printed guides are still wrong.
- ›The corridor is not 65 feet. The lowest fixed span is 64 ft at waterway mile 252.3, and the lowest overhead crossing is a power cable at 68 ft that appears in no bridge table anywhere.
- ›SANDBAR TIMING — what time the bar comes out and what time it goes under, from the real tide curve. Plus the warning that matters: nose onto sand on a falling tide and you are there until tomorrow afternoon.
- ›VHF POSITION REPORT — the exact sentence to say on channel 16, in the format the Coast Guard expects, in type you can read in sunlight. Works with no signal.
- ›FLOAT PLAN — a link you send to somebody ashore. It says plainly that it is a note to a person, not a Coast Guard filing, and it has an ‘I’m back safe’ button.
- ›FIXED: three tide stations in our list — New River Inlet, Ocean City Beach and Wilmington Beach — publish no data at all. Eleven places including Carolina Beach, Snows Cut and the whole Surf City cluster were silently losing their tide panel. They now use a station that answers.
