The trout in this section of the Colorado receive relatively light pressure, especially considering the fine fly fishing opportunities available. Floating is really the best way to cover this water which may, in part, account for the relatively low numbers of fly fishers.
This section, below the Shoshone power station at Grizzly Creek through Glenwood Springs to the Roaring Fork, is a fairly large river, at least by Colorado standards. Good fly fishing and about six good float trips are available from here all the way to Rifle. There is also adequate access from along Interstate 70 and further downriver along Highway 6.
