Filling Criteria As construction progressed on the Upper Basin storage units authorized by the Colorado River Storage Project Act of April 11, 1956, 70 Stat. 105, including Glen Canyon Dam, Secretary of the Interior Udall, in consultation with various interests in the Colorado River Basin, initiated studies to determine how Lake Powell could accumulate storage with the least possible disruption of the many activities, including power production at Hoover Dam, then dependent upon the flow of the river not being restricted in the Upper Basin. Starting in October 1957, meetings of Basin States representatives were held with Interior officials at which . hydrological data was considered. These were later refined by engineering groups of both Basins. Among the conflicting Upper and Lower Basin views were the obtaining of minimum power head at Glen Canyon Reser- voir (elevation 3490 or 6.1 maf) at the earliest practicable time and at the same time dealing with any defi- ciency that might occur in the firm energy generation at Hoover Powerplant incident to filling the Upper Basin Storge Project reservoirs. On January 16, 1960, Reclamation proposed a set of principles and operating criteria (later termed "Fill- ing Criteria ") . These, it should be noted, were based upon a reasonable exercise of Secretarial discretion without attempting to define the outer limits of either rights or obligations of any of the States or of the United 0 ... States. These principles were issued February 12, 1960, and were revised following receipt of comments and suggested modifications in a series of meetings extending from March 1960 to May 1961. On April 2, 1962, Secretary Udall approved Reclamation's redraft of the general principles which ap- peared in the Federal Register of July 19, 1962, 27 F.R. 6851. I.
