Rybaer, picture an underground spring-fed reservoir of undertermined size. It's dammed up, so that a small amount of water drains out, just like any dam. It's filled quite slowly.
Then the flood doors are opened. At the same time, very far downstream, a series of razor-coated portcullises is lowered.
The water rushes out into a steeply downwards sloping, perfectly smooth 10' x 10' tunnel. It slopes downwards in a gentle arc, merging with another tunnel.
For the poor PCs, though, they first learn that there's a wall of water when it smacks into them at (I think) 60-80 miles an hour, driving them downstream into a series of three razor-gates while drowning them! Then the poisonous eels start attacking... Man, kuo-toa are mean.
This is just the kind of Rat Bastard Wile E Coyote madness that gives me convulsions of maniacal laughter. Can't wait to read about this one!
