C"'.) OJ C'-l o ---.. .-, CHAPTER V STAGE TWO PLAN OF DEVELOPMENT 200-foot concrete flume across Adobe Wash, a l40-foot-long siphon under Little Salt Wash, and a 90-foot siphon under East Branch Big Salt Wash. The first 7 miles from Indian Wash to the persigo Wash flume would have a 670-cfs capacity with a l2-foot bottom width and an 8.5-foot depth. The 7.5 miles to the Little Salt Wash siphon would have a capacity of 570 cfs with an ll-foot bottom width and an 8.5-foot depth. The following 3.5 miles to the siphon at the East Branch Big Salt Wash would have a capac ity of 450 cfs wi th an 8. 5-foot bot tom width and a 7-foot depth. The last 2 miles ending at Big Salt Wash siphon, recently constructed under Stage One, would have a capacity of 390 cfs with an 8-foot bottom width and 7.5-foot depth. Check and wasteway structures would be constructed at each change in canal capacity at persigo Wash, Little Salt Wash, and East Branch Big Sal t Wash. Three centerline checks would be added--one in the 670-cfs reach, one in the 570-cfs reach, and one in the 450-cfs reach. Fifty-four lateral turnouts and 30 farm turnouts would be replaced. The initial capacities of the lateral turnouts would range from 1 to 34 cfs, and the farm turnout capacities would range from 1 to 6 cfs. West End Government Highline Canal The west end Government Highline Canal extends for lO miles from the end of Stage One to the Government Highline Canal's terminus 6 miles northwest of Mack. Major existing waterway structures in this section include a 360-foot-long wooden flume across Mack Wash, a mile-long siphon under East Salt Creek, and a 200-foot siphon under Badger Wash. The first reach is 3 miles long ending at the East Salt Creek siphon and would have a l50-cfs capacity with a 6-foot bottom width and as-foot 35
