Approximately 204,000 <br />acres of land are irrigated within the Uintah Basin, although <br />the Bureau's present study is limited to an areu of 104,200 <br />irrigated acres. The combined length of canals and major <br />laterals serving the area exceeds 800 miles. <br /> <br />Much of the irrigation system is cut directly into saline <br />soils and rock. The Unit area contributes about 500,000 tons of <br />salt annually to the Colorado River. Irrigation return flows <br />from the area contribute an estimated 240,000 tons annually, <br />which results in an increase in salinity of ubout 24 mg/l ut <br />Imperial Dam. <br /> <br />In July 1981 the planning team recommended concrete lining <br />for laterals and canals in 11 of the evaluation units.studied. <br />The option selected restricts the use of saved water. The plan <br />would result in a reduction of TDS concentration at Imperial <br />Dam of 7.3 mg/l at a cost of $5l8,000/mg/l/year. <br /> <br />The Regional Director's proposed feasibility report for the <br />Uintah Basin Unit is scheduled for completion in 1982. Assuming <br />the Secretary's report is forwarded in December 1985, advance <br />planning studies would begin in 1987. Based on this schedule, <br />construction on the Uintah Basin Unit could begin in 1989. <br /> <br />cs <br />2/24/82 <br /> <br />-32- <br />
