just had to ask, has anybody run any of the falls? the lower looks runnable, but the line is super thin, any mistake would stuff you in a pothole or slam you into a wall.

Fish ran this falls in a Stiletto with a boogie board for a floor.  It wasn't completely successful from what I know, but, he lived.  Jim Sheflo has a picture of his run....
not recommended.....

I do have the first descent of Tumwater falls!   I  dropped the falls back in 1999 in an inflatable kayak.  Chris Wilson has the 2nd descent back in 2003.

 Lower Tumwater falls is  marginally runnable at  extreme high flows, which opens up the far right line. When i ran it,  my stern was heavy (lack of floatation) and caught the left flowing current and drug me into the undercut left wall.  I was trapped subsurface for nearly a minute plus,  before i flushed to the public park below.   This was, as Horner pointed out, my first entry into waterfall running in the late 90's,  and i was a big drop novice at the time. 
I have run all the upper drops, and all the filler rapids many times, each time being kicked out of the park by the land caretakers or cheered by spectators.   For those interested in running this drop, be sure to have a fast boat, this isnt a finesse falls, this is a clear the undercut on the left falls.  I do have plans to run it again, but next time i'll do it with a smile!

oh, and whats the line on the top falls?
