Fishing Conditions

October 19, 2021

Mornings can be a slow start with the cold water temperatures, so a full nymph rig is the best option until the baetis come out. For nymphs, try a Mega Prince with a smaller Beatis nymph or emerger such as a Green Machine, or a split case BWO. Baetis emergers and dries are best throughout the late morning to early evening.  Smaller Streamers are also working well, try a tan sculpin or sparkle minnow!
