OOutJ85 10 WATER. SUPPLY FOR THE SAN JUAN-.CHAMA PROJECT i, ,< .;>' and that Ule active capacity of Navajo Reservoir would be reduced to 960,000 acre-feet at the end of 100 years. Mr. Reynolds pointed out that the release of 224,000 acre-feet annually for futureM. & I. uses (210,000 acre-feet average) actually constituted an estimated amount of water remaining available after other releases and was not an estimate of re:quirements for M. & 1. purposes as of any :(larticular date. He stated that the. Bureau of Reclamation had estrmated that the municipal and industrial water demands will reach 70,000 acre-feet in the next 60 years, He stated that the shortages indicated were tolerable and pointed out that they were based upon the assumed release of 224,000 acre_feet annually for municipal and industrial purposes, With respect to the Animas-La Plata project Mr. Reynolds stated that New Mexico had no objection to the operation of Navajo Reser~ voir to provide exchange storage benefits to that project as long as requirements from the reservoir for the Navajo, the San Juan-Chama, and the Animas-La Plata projects are all on parity and that any shortages would be shared equitably in proportion to diversion re- quirements. Mr. Reynolds did point out that the water supply studies show clearly that Navajo Dam cannot do a great deal for the Animas-La Plata project and that the problem is finding adequate storage capacity on the Animas River for the Animas~La Plata project. Colorado's studies and position Felix L. Sparks, director, Colorado Water Conservation Board, testified that studies oy the technical staff of the board lead to the conclusions that there is no conflict between the San Juan-Chama and Navajo projects and the Animas-La Plata proiectandthat the San Juan~Chama and Navajo projects have the approval of the State of Colorado. Mr. Sparks stated that Colorado's position and operation studies were premised upon the assumption that Navajo Reservoir would be operated for the regulation of the San Juan River for the benefit of all the. upper basin States and that there would be times when Navajo Reservoir must be operated to release water to satisfy New Mexico uses which, without the existence of Navajo Reservoir, might constitute a legal demand against the State of Colorado for the release of natural streamflows. . One of the studies prepared for the Colorado Water Conservation Board in conneCtion with Colorado's future water needs in the San Juan Basin was a study by Mr. Clifford H. Jex entitled "Stream De- pletion of the San Juan River Basin in Colorado." This very detailed report presents a study of present water use development and the potential water requirements. Mr. Jex's study shows that irrigated land of the basin in Colorado at the present time (March 1960) de- pendent upon the San Juan Basin water totals about 10.9,000 acres with a depletion requirement of 130,400 acre-feet. Mr. Jex estimates that potential irrigation expansion will increase irrigation by an additional 63,000 acres with an additional depletion requirement from San Juan Basin of 114,500 acre-feet. These figures imply an ultimate depletion requirement from the San Juan Basin for irrigation amount- ing to 244,900 acre-feet. Mr. Jex estimates reservoir evaporation of San Juan Basin water in Colorado under future conditions at 15,000 acre-feet annually, municipal water uses of San Juan Basin water in Oolorado under future conditions at 20,300 acre-feet annually, and '-",
