We hit the Cheeseman canyon on the South Platte west and south of Denver on sunday to try to catch the beatis hatch. It was very sunny so the hatch was not great. I did OK with an RS-2, however i did manage one fish on a parachute BWO. The interesting thing about this fish was it had a terrific kype jaw. The fish was not huge, about 16 inches but it had a huge jaw full of big teeth. I thought only large fish have this, maybe it is a function of age not size?
