Description: About Blue River

The Blue River is divided into 3 sections, the Blue in Breckenridge, the Blue below lake Dillon and the Blue below Green Mountain reservoir. In Breckenridge, the Blue has easy access and is a great place to spend a morning or afternoon with the whole family. Below lake Dillon some of the largest trout in Summit County have been caught, mostly on tiny midges and shrimp patterns. Fishing below Green Mountain Reservoir can provide great learning experiences for any angler. Steep access and fluctuating flows, push an angler to test skills and knowledge of all aspects of our sport. When fishing the Blue, be sure to keep an eye on flows, no matter where you are fishing. Consistent flows will lead to amazing fishing, while a dramatic change could introduce streamer fishing like never before. There are amazing Caddis, Midges, Stones and Mayfly hatches, with the Green Drake hatch being the most renowned.
