River Description

A big waterfall (by Florida standards).

Confessing no firsthand knowledge of this site, but looking at the Topozone map (which is linked to), it appears:
1) the overall gradient may be understated -- it looks like it may be more like 50FPM!
2) However, it appears fairly spread out, except possibly the final ten feet (+/-) of drop, as Turket drops into the Alapahoochee.
3) The description for the Alapahoochee includes mention of this, calling it a "12' waterfall into a beautiful grotto".
4) I wouldn't get too excited about this, as the drainage area is quite small (a few square miles). Therefore it will run only during/immediately after heavy rains (which admittedly can happen with regularity here).

My guess is we're talking 'stupid boater tricks' territory here (I.E., better be there early on, while its pouring -- one hour or so later and you've probably missed it.) This assessment would seem further supported by the comment below. That is, the earlier you can hit this (during/immediately after the rain), the taller it is likely to be; Smaller creeks like this will run 'early' in a rain event, whereas a larger river will take (at least slightly) longer to come up.
