Show BOULDER DIVISION The two major proposals in this division, Marble Gorge and Bridge Canyon Dams, are discussed in Chapter VII. The site for the proposed Coconino Dam is in the canyon of the Little Colorado River 8 miles below Cameron, Ariz. Cameron, an Indian trading post and tourist court, is on United States Highway 89, near the junction of that highway and the east entrance to Grand Canyon National Park. The proposed dam, rising 260 feet above bedrock, would create a reservoir having a maximum surface area of 36,000 acres and a minimum surface area of 1,000 acres, with a 40- foot difference in water levels between the two. Considering that there will be a wide variation in water surface area, that the primary purposes of the reservoir are silt and flood control, and that there is not likely to be good fishing, the reservoir will have little recreational use. The other two potential reservoirs in this division are the Alamo on the Bill Williams River and the Sentinel on the Gila River. Both reservoirs are proposed for flood and silt control. Due to the sparse population of the region and the uncertain flow of the rivers, these reservoirs probably will have little or no recreational value. GILA DIVISION All of the proposed reservoirs in the Gila Division will have some recreational use because of the absence of natural lakes in this important recreational region. Each reservoir should be planned and developed to provide for as much recreational use as is possible consistent with the primary use of the water. The McDowell and Horseshoe sites are suitable for the development of important recreational areas serving the Phoenix metropolitan district. The Buttes Reservoir would serve the Florence area; Box Canyon, the Wickenburg area; and Charleston, the Tucson- Bisbee area. 127 |
