Title I Wor1cs and Capital Costs . Reclamation continues to investigate the causes of increased irrigation drainage pumping. In cooperation with the WMIDD, SCS, and others, Reclamation will explore a program of irrigation efficiency improve- ment measures or other measures, with a goal of permanently reducing irrigation drainage pumping to 108,000 acre-feet or less per year. Reclamation's future activities are outlined below. (Also see figure 5.) . Continue discussions among project and ' regional offices concerning increased irrigation drainage. Identify possible causes. Define reduction goal. Identify potential institutional or legal authority. Identify funding options. Meet with WMIDD, SCS, and other interested Federal agencies. . Develop program goals. . Identify roles and commitments for all involved agencies. . Discuss potential activities of all agencies involved. . Discuss implementation schedule. . Discuss monitoring requirements. . Identify specific Federal authorities and limitations. . Identify additional staffrequired and sources of funding. . Develop monitoring plan. Complete implementation schedule. . Execute letter of agreement defIning responsibilities of all agencies involved. Fully implement irrigation drainage reduction program. Coachella Canal Lining As authorized by section 102(a) of Public Law 93-320, the first 49 miles of the Coachella Canal were concrete lined to reduce seepage and, for an interim period, to provide a source of replacement water for bypassed WMIDD irrigation drainage. The lined section conserves an estimated 132,000 acre-feet of water per year. The canal originates as a diversion from the All-American Canal at a turnout point near the Mexican border and runs generally northwest for about 123 miles. (See frontispiece map.) It provides irrigation water for 67,000 acres orland in the Coachella Valley. Shortly after the Coachella Canal was completed in 1948, seepage losses became apparent in the first 86 miles of unlined canal. The most severe seepage occurred in the first 49 miles of the canal, which traversed the coarse, sandy soils of the Imperial East Mesa in California An estimated 141,000 acre-feet of Colorado River water was lost each year in this section. The Coachella Valley Water District (CVWD) operates and maintains the new lined canal. Canal-lining costs are to be repaid by the CVWD over a 4o..year period on an interest-free basis. However, the payments are waived for the interim period when the United States has use of the conserved water. (See chapter II, "Title I Provisions.") 15
