Yeh, it’s nearly always a pleasant little ear wetter. Sometimes all of the ear, other times just the top bit when you’re going through well in low conditions and you think you’ve got away without a wet ear.I know things in caves can and do change but in my experience the water levels in the windpipe are pretty static and it very rarely sumps.
Those signs have been there for many years. I think they date from a time, perhaps in the 90s, when it was sumped due to the natural drain holes being blocked by debris from digging nearby.I guess the signs warning against free-diving are erring on the overly-cautious side then?
If nothing else, the signs are at least a useful indicator that you're on the right track. I was there a few months ago, probably for the first time in 30 years or so and I was very grateful to see the sign on the inward side.Those signs have been there for many years.

It was myself and a fellow caver that placed the signs.Those signs have been there for many years. I think they date from a time, perhaps in the 90s, when it was sumped due to the natural drain holes being blocked by debris from digging nearby.
Teep I know the outlet gets clogged but for FFS how could you locate the outlet at distance flat out in water zero vis?It was myself and a fellow caver that placed the signs.
The windpipe was sumped by debris blocking the drain hole.
We managed to get up the bedding plane from the crab walk and by using drain rods we drained it, signs were left for reference as the level of water reached the sign i.e the windpipe was impassable, if the water reach the signs again it indicates that the drain requires opening again
