. . REPORT BY THE BUREAU OF RECLAMATION, REGION 4 TO THE COLORADO WATER CONSERVATION BOARD February 24, 1967 Work has continued pretty much on schedule on Reclamation Proj- ects under construction in the Upper Colorado River Basin, with an expected slowdown in some areas due to the cold weather. Construction still in progress at Glen Canyon Dam is confined mainly to concrete repairs in the left diversion tunnel and construc- tion of the visitor center. The tunnel work should be completed by May of this year, and the visitor center will be opened around July or August. The Bureau of Reclamation and the National Park Service are coordinating efforts to install exhibits, motion pictures, and to accommodate visitors on a self-guided tour. Blue Mesa Dam is completed and the reservoir now contains about 370,000 acre-feet of water. Work proceeds on completion of the power- plant and installation of the generators. Both of these generators are expected to be operating this spring. Morrow Point Dam has received special mention by the National Society of Professional Engineers in its selection of the outstanding engineering achievements in 1966. The double curvature of the dam and the underground powerplant were cited as being the first of their type in the United States. The contractor at Morrow Point Dam and powerplant has completed about 78 percent of his work. Mass concrete placements in Morrow Point Dam, discontinued last October, will be resumed as soon as the weather permits. It is expected that the dam will be topped out this summer. Other work at Morrow Point has continued through the winter. The contractor has completed excavation of the stilling basin area downstream from the dam and is now making concrete placements in this area. In the underground powerplant the contractor has made the final placement of concrete and has started a general cleanup. We expect to award the powerplant completion contract late in 1967. The first gen- erator at Morrow Point should be operating in the spring of 1969 and the second early that summer. The third feature of the Curecanti Unit, Crystal Dam and power- plant, will be awarded as one single contract for all phases. The ~/F.Y. 1968 program of the President would allow the start of Crystal Dam construction in the fall of 1968. On the Navajo Unit in New Mexico, repair and modification of the outlet works stilling basin is expected to get underway this fall. The stilling basin will be unwatered this spring by separate contract in order that prospective bidders may inspect the work site. Bids for
