Blue River



Blue River

The Blue River can be found winding its way through Summit County, CO and is possibly one of the most beautiful Colorado Fly Fishing spots. This river starts up on Hoosier Pass, flowing north through Breckenridge and Silverthorne on its way to its confluence with the Colorado River. During its trek north, the Blue fills two reservoirs and features many different fishing environments.


  • The Blue River is 65 miles long.
  • The Blue River begins at the southwest end of the Tenmile range in Summit County.
  • The Blue River flows north to Kremmling, Colorado through the Continental Divide.
  • The Blue River provides diverse catches from trout to pike.
  • The Blue River Stream is a gravel-filled class 2 fly fishing stream.

About the River

The Blue River is not a big river, with most sections of it shallow enough for wading. With the close proximity to Lake Dillon, which provides a large percentage of water to the Front Range, the Blue typically sees very low flows. When the river actually rises to reasonable flows (200 to 1200 CFS), the river peaks for fishing. The Blue River is very clear and cold year-round, however, it doesn’t typically freeze in the winter.

Fly Fishing on the Blue River

Breckenridge, Colorado

Breckenridge, Colorado is a short drive to the Blue River. In 30 minutes, you can be fly fishing and taking in the incredible views of the ten mile range. You can find beautiful secluded spots to spend the day on the river, but you will have access to everything you could possibly need in Silverthorne.

Kremmling, Colorado

The small town of Kremmling, Colorado is right by the northern section of the Blue River. Kremmling is an authentic American west town with access to incredible fishing. The views from the Blue River in Kremmling are serene from the river and breathtaking from the Gore Range peaks.
