Seventy-eight <br />percent of the work under the contract has been completed. <br /> <br />The completion contractor at Blue Mesa Dam is concentrating <br />on installation of the turbines and generators and plans to have <br />the plant operable early in 1967. Generation equipment is now being <br />installed, and the switchyard is essentially complete. OVerall <br />completion of the contract is about 67 percent. <br /> <br />On the silt Project the contractor has completed about 93 <br />percent of the work on Rifle Gap Dam and highway relocation. Place- <br />ment of riprap on the upstream face of the dam is essentially com- <br />pleted, but a substantial amount of rockfill remains to be placed on <br />the downstream face. In mid-November, following the final concrete <br />placement in the spillway, closure of the outlet works was accomp- <br />lished. During the remainder of November and December water was <br />pumped over the dam to meet downstream water requirements. On <br />January 1 pumping was discontinued and releases were made through <br />the 6-inch gate chamber bypass line. The contractor is expected to <br />concentrate on resloping the relocated highway cuts and repairing <br />sections of roadway damaged by slides. <br /> <br />Construction work has been finished for Silt Pump Canal, <br />Dry Elk Valley Lateral, and the Grass valley Canal Rehabilitation. <br />In addition, all contract work on Davie Ditch was accepted as sub- <br />stantially complete on December 8. A minor amount of cleanup work <br />will be deferred until spring. All concrete work has been finished <br />and pumping equipment installed in the Silt Pumping Plant. The <br />contract was accepted as substantially complete on December 21, with <br />final testing being deferred until spring. <br /> <br />bdvance Planning <br /> <br />Feasibility studies have been completed for the Battle- <br />ment Mesa project. A meeting was held early in December with the <br /> <br />-iL <br />
