Depending on what source you view, the falls are between 170 and 188 feet high. The heights appear to be completely arbitrary, with the higher heights belonging to tourism boards and the lower heights being more reference-based in nature. Nothing comes close to 220 feet, though.
If common sense were the prevailing wage, I'd always be broke.

Another little known "first" for Tyler Bradt, happened on the Grand Canyon last May. I was on a trip with him and other Montana friends. The night before Lava, the 6 kayakers on the trip decided to have a duckie derby at Lava. It was a SOLO duckie and each 'yaker would run his own boat through, then carry the duckie back up and do the run. Whoever had the most stylish run and remained upright had bragging rights and won the beer pool. After Tyler and Jesse Lakes did a successful NAKED, TANDEM run right down the middle of Lava. everyone else backed out... how do you top that? They did wear pfd's and helmets. Since it was a solo duckie, Tyler in the back, had to hook his feet on Jesse's thighs. They paddled like hades and made it look pretty easy. I was impressed... he still is kind of a pussy though, he never would paddle my Ocoee on the trip!

Well folks, here's what a bored engineering type comes up with during lunch break:
Assumptions:
1) Weight of Paddler & gear 100kg (220 lbs)
2) Aerodynamic drag (tucked boater is assumed to same as bicycle racer, taken from literature): 0.9
3) Frontal area of boat & paddler (assumption is tucked paddler and boat vertical): 0.4 m^2
4) standard air density as per literature: 1.293 kg/m^3
Results:
Velocity of impact after 186 ft (57 m): ~70 mph (112 kph / 31 m/s)
Freefall time: 3.5 sec!
Terminal velocity is reached after ~590 ft (180 m) : ~97 mph (156 kph / 43 m/s)
Freefall time: 6.6 sec!
Just as a comparison, going off a 30 footer (assumption is tucked position):
Velocity: 30 mph (48 kph / 13 m/s)
Freefall time: 1.4 sec.
All this will obviously change if the assumptions above change.
Conclusion: I won't set any waterfall records anytime soon !!
TGG!
