<br /> <br />. <br /> <br />CHAPTER VII <br /> <br />MISSOURI HEIGHTS ENLARGEMENT PLAN <br /> <br />at Hoover Dam would be increased by an estimated average of 0.2 mg/l as <br />a result of the concentrating effect of the river depletion. No increase <br />in salt load would be anticipated from return flows. <br /> <br />Project Features <br /> <br />Missouri Heights Reservoir Enlargement <br /> <br />Missouri Heights Reservoir would be enlarged by construction of a <br />dam at a new location within the existing reservoir basin. The enlarged <br />reservoir would have a total capacity of 10,600 acre-feet and an active <br />capacity of 10,400 acre-feet. The dam would be a rolled earth structure <br />with a height of 50 feet and a crest length of 2,500 feet. Materials for <br />construction are available in the vicinity of the reservoir. The spill- <br />way would have a capacity of 250 cubic feet per second and would dis- <br />charge into Cattle Creek. The outlet works would be capable of discharg- <br />ing 220 cubic feet per second. The new dam would essentially eliminate <br />existing leakage from the reservoir. <br /> <br />Landis Canal <br /> <br />. <br /> <br />The Landis Canal would be 7.2 miles long. It would have an initial <br />capacity of 50 cubic feet per second and a terminal capacity of 8 cubic <br />feet per second. The canal would be earth lined except for in-line struc-. <br />tures with a total length of about half a mile. <br /> <br />Recreational facilities <br /> <br />Recreational facilities would be provided only for assurance of pub- <br />lic health and safety. These would include minimum accommodations for <br />parking and sanitary and trash facilities. <br /> <br />Permanent operating facilities <br /> <br />The project headquarters, consisting only of an office and garage, <br />would be centrally located, probably at Basalt. <br /> <br />Rights -of-way <br /> <br />Construction of project features would require the acquisition of <br />private land and the withdrawal of some Federal land as shown below. <br /> <br />. <br /> <br />Missouri Heights <br />Landis Canal <br />Total <br /> <br />Rights-of-way required for project <br />(acres) <br />Privately owned land <br />Nonirrigated Irrigated <br />Reservoir 140 20 <br />81 <br />221 20 <br /> <br />Federal <br />land <br />40 <br /> <br />40 <br /> <br />Total <br />200 <br />81 <br />281 <br /> <br />57 <br />
