PACIFIC SOUTHWEST INTER-AGENCY COMMITTEE Quarterly Report for Colorado 65-1 Meeting Construction Work on Blue Mesa Dam, CURECANTI UNIT, is being con- tinued on a reduced scale during the winter months, with the work being concentrated on construction of the powerplant structure and channel improvement for about 4,000 lineal feet below the dam- site to give an extra foot or two of effective power head to the turbines. It is expected that the dam embankment construction will be completed by October, 1965. On January 14 a $110,000 contract was awarded to Humphrey Contracting Corporation of Wichita, Kansas, for clearing the Blue Mesa Reservoir area. About 17 percent of the work has been completed on Mor- row Point Dam of the CURECANTI UNIT. The contractor is continuing work on open cut excavation for the powerplant, the keyways and the tunnel portals. Crews are in the process of installing a large concrete batchplant for the 400,000 cubic yards of concrete that will be placed in the 455-foot structure. Placing of concrete is expected to begin in July. A great deal of rock bolting has been required above the open cut areas. At Crystal damsite of the CURECANTI UNIT, all core drill- ing and borrow pit exploration has been completed by the Bureau of Reclamation. Invitations to bid on the first contract for work are scheduled for issuance in the near future. This contract will be for construction of the difficult access road to the damsite. At Rifle Gap Dam, principal feature of the SILT PROJECT, the open cut excavation at the upstream portal of the outlet works tunnel site is complete. Bids were opened on January 19 for cons- truction of the a-mile-long Silt Pump Canal which will convey ir- rigation water to lands on the lower portion of Harvey Mesa. Feasibility Investigations and Reports On the Dallas Creek project, the feasibility report is in progress and is scheduled to be completed prior to July 1, 1965.
