Latest update: 9/19/2019 -- Current flows at Lyons are 36.7 CFS, so expect to fish some dries in town. We have had most of our success in the early mornings and late evenings when water temps are coolest. Surface activity has consisted of sporadic caddis and mayflies. #14-16 elk hair caddis, 16# green humpys, #16-20 Adams parawulffs have all been finding success on top. When the bite slows down around mid day, try fishing with a hopper dropper in order to reach the fish holding low in the water column.
