About Blue River - Above Dillon Reservoir
The Blue River in Colorado offers accessible Gold Medal trout water, ideal for fly fishing enthusiasts. This tributary of the Colorado River boasts excellent brook trout populations, and anglers seeking large rainbow trout will find success in the tailwaters below Dillon Dam. The river is renowned for its classic mountain stream fishing, with the northern stretch near Silverthorne providing a picturesque experience even in peak season. Key insect activity includes Mysis shrimp, Caddis, Stoneflies, and Mayflies, offering diverse nymphing and dry fly opportunities. Fly anglers will appreciate the easy access along Highway 9, with designated parking areas, and the Blue River is well-suited for a 5-weight fly rod with floating line and standard leaders.
