I had to google "piscivorous" haha little to fancy for me but yeah they are natural rainbows no stocking so they do consume some small fry but we pumped some stomachs for fly identification and they really had nothing in them. It was kinda bizarre the small side of the lake really had no hatches what so ever or any indication of previous hatches. The only thing in there stomachs were small round green balls of a goo like substance. But they sure couldn't say no to a dragon fly nymph! The second fish int he picture was 20.5 inches so pushes the 3 pound mark he was the biggest fish of the day. The average fish is definetly bigger on the big side but its always a good day there on the clear green lake!
