Show One alternative was to construct the canal down the west side of Juab Valley from Levan Ridge and release the water into an enlarged Chicken Creek Reservoir. Less than half of the length of this canal would be located on cultivated land, none of which is irrigated. The remainder of the canal would traverse land covered with native vegetation, including sagebrush, some grass, and scattered juniper trees, which would have to be removed during construction of the canal. The land traversed is more rolling than in the cultivated areas, and the canal would be more conspicuous. The irrigation releases from the enlarged reservoir would flow in Chicken Creek through Mills to the Sevier River. A dike several miles in length paralleling U. S. Highway 91 and the Union Pacific Railroad would be required in an enlargement of Chicken Creek Reservoir. The projected alinement of Interstate Highway 1- 15 from Levan Ridge to Chicken Creek Reservoir parallels the railroad, and both would have to be crossed at least twice in delivering water to the reservoir. Under this plan, the reservoir enlargement costs would be excessive0 In addition, the capacity of the Chicken Creek channel from the reservoir to Sevier River is now restricted by a branch line of the Union Pacific Railroad and by agricultural lands along the valley floor. About 5 miles of the creek would have to be channelized and/ or diked under this plan to increase its carrying capacity. An alternative to enlargement of Chicken Creek Reservoir would be an extension of the canal down the west side of Juab Valley, which would involve construction of a siphon under Chicken Creek, below Chicken Creek Reservoir. The canal would then follow the highway alinement to the south about 5 miles over rolling land covered with sagebrush, grass, and scattered junipers, where the flows would be released into the Sevier River. This plan would require storage on the Sevier River below the town of Mills to reregulate the imported water to meet the irrigation demand pattern in the lower Sevier and enable the exchange to central Sevier. An expensive railroad relocation required for the Mills Reservoir site makes this alternative economically unattractive.
