<br />BUREAU OF RECLAMATION
<br />
<br />For Release FEBRUARY 12, 1960
<br />
<br />PROPOSED FILLING CRITERIA FOR GLEN CANYON RESERVOIR, UPPER
<br />COLORADO RIVER STORAGE PROJECT, ANNOUNCED
<br />
<br />Tentative principles and operating criteria to govern the fill-
<br />ing of Glen Canyon Reservoir, the principal storage unit of the Colo-
<br />radoRiver Storage Project, were proposed today by the Department of
<br />the Interior.
<br />
<br />The proposal is to be forwarded to members of the engineering
<br />groups in the Upper and Lower Basin which performed the operating
<br />studies, in cooperation with the Bureau of Reclamation, which lead
<br />to the proposed filling criteria. A meeting is to follow in which
<br />the affected States will have an opportunity to comment on the pro-
<br />posal after which a final decision will be made by the Secretary of
<br />the Interior on the filling procedure.
<br />
<br />The four storage units in the Colorado River Storage Project
<br />which will be affected, together with their individual storage capa-
<br />cities, are:
<br />
<br />Glen Canyon, on the Colorado River 13 miles downstream in
<br />Arizona from the Utah State line, 28,040,000 acre-feet
<br />
<br />Navajo, on the San Juan River 34 miles upstream from
<br />Farmington, New Mexico, 1,709,000 acre-feet
<br />
<br />Flaming Gorge, on the Green River in Utah 60 miles be-
<br />low Green River, Wyoming, 3,789,000 acre-feet
<br />
<br />Curecanti, a system of two reservoirs on the Gunnison
<br />River downstream from Gunnison, Colorado, 1,032,000 acre-feet.
<br />
<br />All storage units except Curecanti are now under construction
<br />and funds to initiate construction of the first reservoir of this
<br />unit have been requested in the President's budget for fiscal year
<br />1961.
<br />
<br />In addition to a total of 34,570,000 acre-feet of storage space,
<br />the four units will have 1,108,000 kilowatts installed hydroelectric
<br />capacity.
<br />
<br />Filling criteria issued in advance of actual storage, probably
<br />starting in 1962, are desirable in order that all parties concerned
