Bit of a slower day on the Colorado. We floated South Canyon to New Castle and had a slow start nymphing. We switched to throwing streamers and had an immediate increase in action. We hooked several nice fish on grey double gongas and white/tan sex dungeons. Streamer success continued until about 1:00 and slowed significantly. We switched back to nymphing and picked off a few fish on frenchies and blue zebra midges. Overall a day where we had to work for them but great weather and beautiful scenery! Good luck out there!
