After payment of power construction, and operation and maintenance costs, available forecasts are that sufficient surplus revenues will be available to pay off the remainder of the reimbursable costs of the initial phase approximating $45 million within 50 years. The following tabulation shows the distribution of construction costs of the initial phase, San Juan-Chama project and the repayment schedule:Purpose Cost allocation Repayment by beneficiaries Total repayment: Irrigation $53,400,000 $8,000,000 $53,400,000 Municipal and industrial water 29,200,000 29,200,000 58,600,000 Future uses 3,000,000 3,000,000 3,000,000 Recreation 1400,000 Total 86,000,000 40,000,000 115,000,000 PARTICIPATING UNITS, COLORADO RIVER STORAGE PROJECT-The Navajo Indian irrigation and San Juan-Chama diversion projects were included in potential participating units of the Colorado River storage project authorized by Public Law 485, 84th Congress, 2d session, approved by the President on April 11, 1956. In section 2, Public Law 485, the Secretary was directed, in carrying out investigations in the Upper Colorado River Basin, to give priority in completing planning reports among others to these two units. The main works of both participating projects are located in New Mexico. The Navajo Indian project will receive irrigation water supply for a net area of 110,000 acres of irrigable land from Navajo Dam and Reservoir, which was authorized by Public Law 485. Construction contracts have been awarded and this dam and reservoir are scheduled for completion in 1963.The San Juan-Chama project plan contemplates the ultimate diversion of 235,000 acre-feet from the upper tributaries of the San Juan River, a tributary of the Colorado, for irrigation, municipal, industrial, and other beneficial uses in the Rio Grande Basin and a limited quantity in Canadian River Basin through exchange. However, S. 3648 confines the authorization to an initial stage to divert 110,000 acre-feet with provision for basic facilities for expansion to provide for the ultimate development. Recreation and fish and wildlife protection will be features of both projects.Public Law 485 looks to the full development of the land and water resources of the Upper Colorado River Basin. Construction costs of irrigation developments beyond the ability of water users to repay will be financed from surplus power revenues from Glen Canyon Dam and powerplant and other payments into the Upper Colorado Rive
