Here’s a report on a restoration project on the Roaring Fork River, from the Aspen Times. From the article:
A half-mile stretch of the Roaring Fork River 2 miles east of Aspen is slated for restoration work later this year, according to an announcement by the Aspen Center for Environmental Studies. ACES director Tom Cardamone announced that a coalition of local, state and national agencies and organizations will be involved in the project, which is meant to restore the river to “a stable, healthy channel, and reclaim two damaged sections of river bank which are undercut and collapsing.” The agencies and organizations involved include ACES, the Aspen Valley Land Trust, the Colorado Division of Wildlife, the U.S. Army Corps of Engineers, The Nature Conservancy and Pitkin County.
