It is always dangerous, not just now.
I've jumped it, but I'm older and wiser now. I'm pretty sure that people have died there in the past. Even if you don't hit the bottom you can still break your spine. I did a flip there once and landed wrong and chipped my teeth from hitting so hard.
Jumping off of cliffs into rivers and lakes is a very high risk activity. I don't do it anymore and I cringe every time I row through the hot springs on the Upper C while people are hucking, especially if they are doing it from the hot springs side. The hot springs side is very dangerous at any flow level.
Take it from me, I broke my neck in 2006, you don't ever want a spinal injury. Even if you are not paralyzed the pain is intense and lasts for years, maybe for life. Take the biggest nerve in your body and hammer it... that is what a spinal injury is.
