March 2018 – another expedition of the same team added more than a kilometer of tunnels to the cave map. They also measured the depth of The Last Nemo Station terminal siphon lake. It was 8.5 m (28 ft) and so the total cave depth reached 2,212 metres (7,257 ft).
At least the siphon with the lowest surface level was measured, but it does not say if by diving one could get even deeper.
Is that the end of the cave at the very bottom, or is it just the level wehere water starts and it could be possibly deeper?
Potentially goes deeper.
