that even with the additonal power sources from the Colorado - Big Thompson Project and from the Glendo Project there will be shortages after 1960. The only direct benefit to Colorado from the Glendo Project is an increase in the electric power generating; capacity in the area from which northeastern Colorado is served. The Project represents a potential detriment to Colorado only in so far as its construction and operation, when considered in connection with the 1945 decree, may constitute a downstream deve- lopment which, if acquiesced in by Colorado, may prove to be a barrier to any Colorado effort to modify that decree. In this connection T,2r. Gildersleeve made a study to deter- mine the apparent increase in stream depletion by reason of Glendo. To do this he analyzed the operation studies of the Bureau. Attached hereto are the two summary sheets of Mr. Gi.ldersleeve's study. Exhibit A is based upon the Bureau's "Control Study" which is without Glendo. Exhibit B is based on the Bureau's "Operation 9 b" which is with Glendo. The diff- erence between the two next to the last figures in the right hand columns (i.e. 75.2 -59.6 or 15,600 acre -feet) represents ivir. Gildersleeve's conclusion as to the increase in stream de- pletion in the 1940 -1946 period by having Glendo on the stream. The Bureau ope-(a Lion tudies are based upon a depletion of 33,800 acre -feet because of the oper�.tion of the full 20,000 acres of the Kendrick Project. Representatives of the Bureau stated that he present storage to the credit of Kendrick was over 1,000,000 acre -feet. At the end of the 1950 water year the storage to the credit of Kendrick was 990,000 acre -feet. It was pointed out the 75% of this Kendrick storage was secured in one year. In the consider_:_tion by Colorado of the Glendo Project due regard must be given to the Act of August 9, 1937, which appropriated funds for the construction of the Kendrick Project in Wyorning. This act reads in part as follows (50 Stat. 595): "Provided, That in recognition of the respective rights of both the States of Colorado and Wyoming to the amicable use of the waters of the North Platte River, neither the construction, maintenance,nor oper- ation of said (Kendrick) project shall ever interfere with the present vested rights or the fullest use here- after for all beneficial purposes of the waters of said stream or any of its tributaries within the drainage basin thereof in Jackson County, in the State of Colorado, and the Secretary of the Interior is hereby authorized and directed to reserve the power by contract to enforce such provisions at all times." Consideration must also be given to Paragraphs I and XIII of the 1945 North Platte decree which read thus: - 4 -
