CHit 8 <br /> <br />Memorandum <br /> <br />To: ~ Chief, Curecanti Field Division, <br /> <br /> <br />From: Er Regional ,Supervisor of Water and <br /> <br />Subjectf .Operation of Auxiliary Outlet Works at Navajo Dam, CRSP <br /> <br />Pe~ssion is granted to deviate from the Designers Operating Criteria <br />to operate the Navajo Dam 4 X 4 auxiliary outlet works with the water <br />surface elevation above 5920. The original restriction was placed on <br />the operation of the gate before the flip bucket was added to the <br />outlet. The gate was tested this spring by Lee Gerbig of the E&R <br />Center and Jack Langford of the Regional Office and found to operate <br />satisfactorily under the higher reservoir water surface elevation. <br />Both the guard gate and the regulating gate should be well lubricated <br />before operation at the higher head. <br /> <br />These gates can be operated at the higher head while the main outlet <br />works are drained and repairs completed. The Review of Operation and <br />Maintenance examination will be held on October 1, 1979, and an <br />e7~ftlination of both outlet works will be required at this time. <br /> <br />I' <br /> <br />Don H.
