Fairchild <br />August 19, 1974 <br />Page thirteen <br /> <br />to have more personal contact with the individual participating <br />farmers. However, to offset this, additional acreage was picked <br />up on a more simplified irrigation guide system. <br /> <br />b. Lower Gunnison Unit - Irrigation scheduling was <br />initiated in the Uncompahgre Project area during 1974. The Water <br />Users' Association hired a field representative to do all field <br />work in the project area. The bureau of Reclamation reimbursed <br />the Uncompahgre Valley Water Users' Association for the expenses <br />incurred for this field representative during FY 1974. Approxi- <br />mately 1,500 acres are being scheduled under the simplified irriga- <br />tion guide program and approximately 3,000 are being scheduled under <br />the more sophisticated fie1d-by-fie1d system. <br /> <br />Systems Improvement <br /> <br />a. Grand valley Unit - Work on feasibility level <br />cost estimates was completed on lining of all canals and laterals <br />within the Grand Valley area. This includes both private and <br />Federal projects. Water quality and quantity measurements are <br />being continued, and a detailed study is being conducted in the <br />Peck and Beede Wash area to determine the effects of, salinity <br />abatement programs. <br /> <br />b. Lower Gunnison Unit - Work was initiated early <br />in the ,spring of 1974 to determine the extent and layout of all <br />canals and laterals on the Uncompahgre Project area. This work is <br />being done from aerial photographs that were obtained by the U. S. <br />Department of Agriculture. continued water quality and quantity <br />sampling throughout the project area was accomplished during the <br />fiscal year. ' <br /> <br />; <br /> <br />c. G1enwood-Dotsero Sprinqs Unit - Work continued <br />on preparing data for a feasibility report to be published by <br />July 1, 1975. Work during the past year included evaluation of <br />alternate methods of disposal of the saline water, either by <br />evaporative ponds or by a mu1tiplaced distillation unit. <br /> <br />Additional geophysical surveys were performed by contract <br />at the Dotsero area, and the data on underground water flow has <br />been expanded. A contract was negotiated with Colorado State <br />
