Historical River Flow

River Information

The Roaring Fork is another one of Colorado's most famous freestone rivers. This major tributary of the Colorado River begins near the town of Aspen and runs hard for approximately 70 miles before it reaches the Colorado in Glenwood Springs. Fishing can be outstanding for the entire length of the river, offering anglers the opportunity to fish a variety of conditions as it grows in size heading towards the Colorado. The river is most often fished on foot, however does offer the option to float fish all 12 months of the year, on most years. Most of the floating takes place from Basalt to Glenwood Springs, while most of the wading takes place from Aspen to Basalt. Hatches are abundant on the Roaring Fork and the fish can grow quite large and powerful. This river should definitely be on any angler's list when visiting the areas of Aspen, Basalt, Carbondale or Glenwood Springs.

Seasonal Conditions

The Roaring Fork can be fished year round, however, like many rivers in Colorado, can really shine during the months of March through November. Stoneflies are abundant in the river so fishing some sort of Stonefly nymph (Rubberlegs, Stone Bomb, 20 Incher) followed by a Mayfly or Caddis nymph is usually effective the majority of the year. By summertime, the Mayflies, Stoneflies and Caddis become very active and provide excellent dry fly fishing opportunities as long as you match the hatch. Terrestrial patterns will also take fish during the Summer and into the Fall. Streamers can be fished effectively from Spring through Fall.
