The blue creek sees very few fishermen because access is challenging. There is somewhat of a trail for a ways thanks to some dedicated rock climbers who have put many hrs. in creating a route to a climbing wall. During runoff stay out unless you use the ropes stetched across the creek.
The water is chalky even when low which made nymphing mandatory. The rainbows were abundant ranging from 12 up to 15 in. The closer you get to the Gunnison the bigger the fish and the more challenging the hike. It would be difficult for the fish to move up from the Gunnison because there are 50 ft. water falls between some the deep pools. What a solitary beautiful experience.
