Blue River North of Silverthorne
UPDATED: 10/19/2026
Flow: 65 - 75 cfs River Graph
Guide Tip of the Week:
Small Dry flies have been productive in the shallow stretches of river, but a nymph rig will be needed to target the larger fish sitting in deeper water, and should contain a meatier attractor nymph followed by realistic midge and Baetis patterns. Unfortunately, we are not really seeing the salmon make their way out of GMR due to low flows at the inlet. If you do manage to find one, These fish strike out of aggression, and can be triggered by red, pink, and orange colors.
Always keep an eye out for spawning brown trout in the fall, and avoid wading on, or fishing near their redds!

The Blue River North of Silverthorne town limits contains some beautiful public water and breathtaking views. Unfortunately, it does not boast the highest trout population in some of its public sections. This does not mean there are no fish to be caught, but you may have to be patient and work a little harder to hook up. However, you do always have the shot at hooking the fish of a lifetime, a large trout that usually reside in private sections of the Blue sometimes venture into public waters. Happy hunting.
