Trinity and Spring Creek Powerplants will be completed early in 1964.

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 . Fish ladders are incorporated on either side of the dam to allow fish to reach spawn­ ing areas upstream.

RECREATION, FISH, AND WILDLIFE

Central Valley Project is multi-pur­ pose. It is constructed for many. uses, including recreation and fish and wildlife conservation. Costs allocated to these facilities are, in the main part, nonreimbursable , being considered of national benefit. Recreational areas are maintained at reservoirs and where 6,750 ,000 visitor-days of outdoor recreation were enjoyed by people from all parts of the country . These areas are admin­ istered by the U. S. Forest Service, National Park Service, Bureau of Reclamation. the State of Cali­ fornia , or by coun ty governments. W hiskeytown Reservoir area in Shasta County has been added to the project recreational areas. This reservoir covers about 3,250 acres and has about 36 miles of shoreline. T here will be three public-use areas around the reservoir adminis­ tered by the Nationa l Park Service. The Lewiston Fish Hatchery was com­ pleted and transfe rred to operation al status as of J uly I, 1963. In accordance w ith a contract be­ tween the United States and the State of California, full custody and responsibility for operati on, main­ tenance, and repair of the hatchery were given to the State Depar tmen t of Fish and G ame. At Red Bluff Diversion Dam on the Sacramento River fish ladders are being constructed to allow fish to pass over the dam to spawning ~~--.. areas upstream. -====-----­
