The Blue River is a tributary of the Colorado River that originates in the Ten Mile Range on the western side of the continental divide. The river flows north through the town of Breckenridge and then into Dillon Reservoir. The northern section of the Blue below Dillon Dam to Kremmling is designated Gold Medal water. The Blue river is most famous for its tailwater section directly below the Dillon Dam in the town of Silverthorne. This easily accessed section is home to numerous trout over 20 inches. Downstream of Silverthorne to the Green Mountain Reservoir, the Blue River flows next to Highway 9. This section is a mix of public and private water with numerous marked public access points. The tailwater section below Green Mountain Reservoir is also designated Gold Medal Water. The first three miles below Green Mountain Dam are public, while the remaining section to the town of Kremmling and the confluence with the Colorado River is private. The lower section of the Blue can be very productive, but fishing is very dependent on river flows.

The Blue does not have very significant peaks of high water so overall remains very wadeable. The river bed does consist of very slick boulder and deep pools so caution is always advised.
