If your talking the Rainbow River..... cant say for sure other than its clear as clear water can get ......................did notice some green carp fishermen over the years but not much in the line of crappie fishermen. AWESOME river to take the family out for a tube float.............. one of the best in the state IMO. Just remember to mix up some jungle juice for the float........................ good stuff I'm telling ya. (FWC keeps the river clear of reptiles which is a plus)
