The Colorado River Research Program
September 09, 2008
The Colorado River Research Program in Grand Canyon National Park was initiated by the National Park Service in 1973 to secure scientific data to provide a factual basis for the development and the implementation of a plan for appropriate visitor-use of the Colorado River from Lee's Ferry to Grand Wash Cliffs and for the effective management of the natural and cultural resources within the Inner Canyons. The intensified research program consists of a series of interdisciplinary investigations that deal with the resources of the riparian and the aquatic zones and with the visitor-uses including river-running, camping, hiking, and sight-seeing of these resources, as well as the impact of use and the upstream operations of Glen Canyon Dam upon canyon resources and visitor enjoyment.
Here are the Technical Reports:

NOTE: Study #5 recommended the following on page 48: "Economic, biological, political and time facets should be explored for every conceivable plan to restore the habitat. A plan to restore a portion of the Colorado River in Grand Canyon area on a seasonal babsis (seasonally adjusted flows) to coincide with the spawning of [humpback chub] should be explored. Possible plans include: Removal of Glen Canyon Dam and construction of a by-pass around Glen Canyon Dam.
