The 230-kv. transmission lines from Trinity, Clear Creek, and Spring Creek Powerplants to Keswick, and Keswick to Elverta and Tracy were completed and placed in operation. This virtually completes the 446 circuit-miles of trans­ mission lines constructed to carry Trinity power to the load centers. Red Bluff Diversion Dam, on the Sac­ ramento River below the City of Red Bluff, is now 85 % complete. Eleven 60' x 18' fixed-wheel gates are being installed for the overflow weir, and a sluice-way and four 11.5' x 10' radial gates will be placed in the outlet to the canal headworks. The dam will divert water to the Corning and T ehama­ Colusa Canals. Fish ladders are incorporated on either side of the dam to allow fish to reach spawn­ ing areas upstream.
