Show VI-32 UPDATING THE HOOVER DAM DOCUMENTS COLORADO RIVER STORAGE PROJECT 27 The Congress, by Public Law 485, 84th Congress, 2d session, authorized the Colorado River storage project and participating projects. In so doing, it excluded the Echo Park unit (consisting of Echo Park Dam and Split Mountain Dam) and included the Flaming Gorge, Navajo, and Curecanti units in the initial stage. As a result of this change and because it was felt that administrative people and the Congress were entitled to a reappraisal of the project, the Bureau undertook an economic and financial analysis of the storage project as it had been authorized. This analysis was presented to the Congress and was published as Senate Document 101, 85th Congress, 2d session. In order to make such an analysis, it was necessary that there be assumed certain procedures under which storage would be accumulated in the reservoirs. For this purpose there was prepared what has subsequently become known as the "Hydrologic Bases." At about this time, there had been indicated widespread interest in the problem of initial filling of the Glen Canyon reservoir. As a result, a meeting was held in Washington, D.C., on October 24, 1957. The Governors or their representatives and other interested persons from the seven states of the basin attended that meeting. At that meeting the statement on "Hydrologic Bases" was presented to the assembled group. That statement was subsequently revised in certain aspects and, as revised, became a part of Senate Document 77, 85th Congress, 2d session. Also at that meeting representatives of Arizona, California, and Nevada offered for consideration the so-called Tri-State Criteria. These criteria, with a slight modification, were published as Senate Document 96, 85th Congress, 2d session. A second meeting was held on December 4, and 5, 1957, in Las Vegas, Nev. This meeting was also attended by the Governors or, in some cases, their representatives and others from the seven States. At that meeting the Interior Department offered to meet with any of the States singly or jointly upon their request. Subsequent to that meeting there was established a group of engineers representing the States of Arizona, California, Nevada, and the Bureau of Reclamation. This group was to provide additional information of an engineering nature aimed specificalhT at the filling problem. This engineering group met on the following dates in 1958: February 3 and 4, April 17 and 18; June 25 and 26, September 23 and 24, and December 8 and 9. The group met on March 4 and 5 in 1959, and also met with the upper basin engineers on March 30 and 31 and August 4, 5, and 6, 1959. During this period the group prepared more than 200 preliminary studies, some by manual process and others by electronic digital computers. These studies were exploratory and, among other things, provided a general framework for the studies subsequently made. An additional 65 operational studies have also been made covering three assumptions of runoff sequence for a 36-year period and 8 general sets of filling criteria. A summary, in report form, of the work of this group was transmitted to you by letter of August 20, 1959, signed by A. J. Shaver for the lower basin engineering group. By letter of August 27, 1958, the engineering committee of the Upper Colorado River Commission requested that the Department appoint a group of engineers to meet with the committee also for consideration of possible filling criteria. The same Bureau of Reclamation engineers met with the commission's committee. One |
