Harrison Bay

From SAUwiki

It is right across from the nuclear power plant. There are two awesome rope swings that swing like 25 ft out over the water and a cliff to jump off of that you can rock-climb back up. The water is pretty dirty though.

I've been there, but wouldn't go off it; it is a dangerous place. They had a ramp down the hill with a little jump -- people would ride a bike down and jump off. While I was there someone lost their contact lenses when they hit the water. It is high enough that any debris floating in the water could cause serious injury. The TVA people try to stop folks from using these places. The bank is steep and rocky. If you let go of the rope too soon or too late, you would definitely be injured.
