It happened just after 7 p.m. on Oatka Creek.
Deputies say a second man went to help him but he also wound up on the landing. Emergency crews say when they went to save the men, the first one was very uncooperative. It took both crews until 9 p.m. to rescue both men from the falls.
The first man was taken to Strong Hospital for minor injuries and a mental health evaluation. Investigators say alcohol may have played a factor.
