.." _,n', ~." _~' 1 ~ V tli~: . ;;/BALT PROJECT PROJECT PLAt'f. FEATURES. ilND COSTS The lower 12 miles of the COllduit would involve earth excavation through nonirrigated pasture lend vhere the vegetative cover consists of scrub oak and brush. Clearing requirements and canal lining requirements would both be light. Landis Canal The Landis Canal consistinG almost entirely of open eal~h section would head at the outlet of Missouri Heights Reservoir and would extend northvest approximately 22.8 miles to its terminus at the head of the Spring Valley lateral system. The .ce.nal capacity would be 220 second-feet for the first 7.5 miles above the Cattle Creek outlet, 140 Second-feet for the nel<"t 13.1 miles above the Landis Creek outlet, and 50 second-feet for the remaining 2.2 miles which includes an 0.8-mile-long siphon across Landis Creek. . Excavation would be mostly in reddish sand clay loam soils vith some Imra cobbles, boulders, and broken sandstone. Gravelly soils would be encountered near strear1 channels but there appears to be sufficient fine material along the canal route to assure satisfactory construction condi- tions. Cross slopes average about 20 percent. Turnouts, wasteways, drop structures, measuring devices, bridges, and culverts would be provided as lleeded along the canal route. Spring Valley lateral The Spring Valley lateral would head at the outlet 01' the Landis siphon of the Landis Canal and extend southwest about 2.8 miles, convey- ing irriga.tion water to lands on the Spring Valley Bench. The lateral would consist of open canal section and would have a capacity of 50 second- feet. No special construction prOblems are anticipated. Carbondale Canal The Carbondale Canal would head on a natural channel approximately one mile below the outlet of the Missouri Heights Reservoir. It would meander southwest a total distance of 12.6 miles, terminating at Thomas Creek about 5 miles southeast of Carbondale. The canal would convey project vater to lands in the Carbondale erea. About midway along its course the canal would cross the Roaring Fork River by meHns of a siphon 6,800 feet long. ~'he Sopris Canal would branch from the Carbondale Canal at the outlet of the siphot:!. . The Cffilal would have a capacity of 55 second-feet from its head to the outlet of the Roaring Fork siphon and 30 second-feet beyond that point. It would consist of about 10.lt miles of open earth section and 2.2 miles of concrete section. Clearing would be light and most of the 15
