Dived the spring this past weekend. Fun little dive- easy entry, good facilities. Nice deep hole near the entry point that drops to around 75-80 feet depending on the river height. Couple of small caves at the bottom that are too narrow to penetrate. A warning though: there is a $15 per diver fee that is not posted on their website or mentioned on the state park website. Also there is sign prohibiting lights which is a shame since there's a neat, safe, cavern at the bottom of the spring.
