| 摘要： | This science plan describes proposed monitoring and research activities to be conducted by the U.S. Geological Survey's Grand Canyon Monitoring and Research Center (GCMRC), should the Secretary of the Interior approve an experimental high flow at Glen Canyon Dam in spring 2008. A high-flow release from the dam has been proposed in 2008, not only to rebuild sandbars and aid the endangered humpback chub, but also to benefit various downstream resources, including rainbow trout (Oncorhynchus mykiss), the aquatic food base, riparian vegetation, and archaeological sites. Additionally, the system is currently enriched with sediment as a result of repeated tributary floods from the Paria River in late 2006 and fall 2007; the current level of sand enrichment is greater than it has been since at least 1998. / Supplementary Notes: Sponsored by Geological Survey, Reston, VA. / Availability Note: Product reproduced from digital image.
