COLORADO RIVER STORAGE PROJECT 27 . The Congress, by Pnblic Law 485, 84th Congress, 2d session, authorized the Co1prado 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 auth.orized. This analysis was presented to the Con- gress and was publi~hed 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 therreservoirs, 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., onOctober 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 cer- tain 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 atteuded by the Governors or, in some cases, theirirepresentatives 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 Recla- mation, This group was to provide additional information of an engineering nature aimed specifically 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 inanual 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 Au!);ust 27, 1958, the engineering committee of the Upper Colorado R)ver Commission requested that the Department appoint a group of engineers to meet with the committee also far consideration of possible filling criteria, The same Bureau of Recla- mation engineers: met with the commission's committee, One . .
