Removing water from JJ based stage

[gurdoman]

I already asked Lensho this, but just in case he is too busy to help me I'll ask this here.

I would like to know if you could help me with a stage I'm "fixing", I grabbed this stage http://www.mediafire.com/?6ag238msqngcbtr and moved a couple of vertex to have 3 stones on top of the waterfall, and make the waterfall a dying point (not walking on it).

The problem is that when you fall, you start to swim just like a meter below and go all the way to the left, I understand that that happens because it's based on Jungle Japes, but after searching like crazy I couldn't find a workaround.

So what I want is for the waterfall to be a falling spot, no water, no nothing just falling.

Please help
