The powerplant is scheduled to go into operation in early 1967. All work under the contract to clear Blue Mesa Reservoir has been accomplished. At Morrow Point Dam, virtually all outside work has come to a halt due to the cold weather. Concrete placements in the dam as~}rell as other outside work will be resU11led in the spring as soon as weather permits. Underground excavation, drilling and installation of rock bolts, tunnel supports and chain-link fabric continues in the penstock and foundation tunnels and in the powerplant chamber. Work under the contract is almost 40 percent completed. The difficult access road into the Crystal damsite--third of the three major dams comprising the Curecanti Unit--is substantially completed. Exploratory drilling at the damsite is moving ahead. Present schedules call for invitations for bids for the Crystal Dam and Powerplant within the next few weeks. The dam will be an earthfill structure about 220 feet high, 730 feet long, containing about 1,900,000 cubic yards of mate- rials. Work will also include constructing a powerplant, to house one 28,000-kilowatt generator, and a switchyard. At Rifle Gap Dam, principal feature of the SILT PROJECT, major con- struction activity during the reporting period includes placement of dam embankment, excavation for the spillway stilling basin, placement of con- crete in the outlet works intake structure, and grouting in the outlet works tunnel and in the dam abutments. Placement of embankment in the dam has reached a point where very little additional embankment work can be accomplished prior to diversion of the stream through the outlet works 2
