- 15 - When completed, the Navajo Recreation Area around the Navajo Reservoir on the San Juan River is expected to have some 600,000 visitor-days per year use. The Arboles site portion of this recreation area lies partly within the southeast part of the watershed. It is operated by the Colorado Game, Fish, and Parks Department, and is expected to have a large share. of the visitor- day use. BASIS FOR PROJECT FORMULATION The primary project objective is to formulate a combination of land treatment and structural measures that will most economically provide solutions to the principal watershed problems. These will include: (1) installation of needed land treatment measures on both irrigated and nonirrigated lands to reduce sediment and erosion damages and to obtain a more efficient use of irrigation water through improved water management on individual farms and ranches, (2) installation of feasible floodwater-retarding structures, (3) development of a program of water management by the water carriers and individuals that will reduce water uses to actual demands of the crops, (4) rehabilitation of the main canal system in order to reduce water losses and provide. a more efficient dis- tribution of water, and (5) improvement of irrigation laterals serving small groups of farmers. Landowners and operators agreed that improvement would be made in the management of the farm and ranch units and the canal systems that would (1) improve farm incomes, (2) continue deSirable land use and achieve balance in the production of crops and feeds for local consumption, (3) improve soil and water conservation in the watershed, and (4) apply and develop on farm and on the water delivery system, an improved program of delivery, application, and use of irrigation water. A survey was made to secure information on (1) land use, (2) crop production costs. and yields, (3) amounts and kinds of land treatment measures applied and to be applied, (4) future plans for farm and ranch operation with and without the project, (5) flood- water and sediment damages, and (6) whether a full.or partial water supply was available with present cropping system. No change in cropping was indicated by this survey. Federal land- administering agencies agreed to develop programs for the conserva- tion and use of the watershed lands.
