Excerpt from Operation of Glen Canyon Dam: Draft Environmental Impact Statement; Appendices Grand Canyon is an internationally significant natural landscape feature. Ironically, the Colorado River, the physical feature responsible for carving Grand Canyon, is now the most heavily regulated large river in North America. The physical hydrology of Colorado stream flow, as with the associated sediment load and dissolved constituents transported by the river, have changed dramatically since closure of Glen Canyon Dam in 1963. Numerous studies, including those sponsored by the us. Bureau of Reclamation's Glen Canyon Environmental Studies since 1982, have documented these changes. The Grand Canyon Protection Act of 1992 has directed the Secretary of the Interior to establish and implement long-term monitoring programs and activities that will ensure that Glen Canyon Dam is operated in such a manner as to protect, mitigate adverse impacts to, and improve the values for which Grand Canyon National Park and Glen Canyon National Recreation Area were In response to this directive, the Glen Canyon Darn eis resource management agencies and interests have initiated the planning of a long term monitoring program which would permit continued evaluation of the effect of Glen Canyon Dam operations, as described in the Record of Decision, on the riverine environment of Grand Canyon.
