NORTHERN MINES & CALIFORNIA REPORTS BIS FEIN FF eB Her rt EE et +P et CONSTRUCTION ACTIVITY continues at the site of the NID's Dutch Flat No, 2 powerhouse on Bear River. On the left, a Pacific Gas & Electric Co. crew installsthe permanent standby power facility. In the center the air housing of the generator can be seen protruding above the concrete roof deck of the underground powerhouse. Oil circuit breakers and the main transformer are seen on the right. “STACKING IRON" to construct the rotor spider of the new Dutch Flat powerhouse generator is seen here. The precisely engineered laminations are individually hand placed to build up the three foot thick rotor. Ron Geisler, general forman of Wismer & Becker forces, subcontractors for equipment installation, confers with mechanical foreman, Fred Brown. Blackberry Control Test Program Is Shown Here Extensive tests on the control of wild blackberries were viewed recently on a tour here by the University of California Agricultural Extension Service. Results of replicated trials using eight different chemicals to control this foothill pest were studied of officials of the Agricultural Commissioner's Office, U.S. Forest Service and California Division of Forestry, the Department of Public Works and Soil Conservation Service from Placer and Nevada Counties. Farm Advisor, Les McCabe of Nevada County, and Jack Herr of Placer County, along with U.C. Weed Control Specialist Bill Harvey of Davis, reported on evaluation of test plots for blackberry control with chemicals to use, rates of application, methods of application and timing. In summarizing results Harvey stated the most economical chemical for control of blackberries appears to be the ester form of Silvex. The best time of application on last years trials was October. Additional information on test plot work in this foothill area on wild blackberry and poison oak control can be secured from the Farm Advisor's Offices in Grass Valley or Aubum. The Nevada Irrigation District's $59 million Yuba-Bear River > hydro-electric project, now moving into final stages of construction, is listed as 86 per cent + complete according to the 25th progress report of the district's project managers, Ebasco Services, Inc. The report, which covers the period ending June 30, noted there was an average construction force of 433 men on the job and of the approved project cost of $59,481,640, atotal of $45,009, 339 had been expended to the end of the period. The project completion date is Dec. 31. Final work on completion of the last few feet of the embankment of the new Jackson Meadows Dam was started. At the end of the period eight feet remained to be placed. Atthe end of the period the reservoir was storing approximately 58,000 acre feet. The Jackson Meadows segment of the project is listed as 97 per cent complete. Water was delivered through the new Bowman-Spaulding Conduit for the first time at the beginning Contracts Are The award of two contracts for work on Pacific Gas and Electric Company's $9.2 million Drum No. 2 Powerhouse project on the Bear River in Placer County has been announced by the company. The project will add 45,000 kilowatts to the PG&E system when completed this December, John F. Bonner, PG&E senior vice president, said Rothschild, Raffin and Weirrick of San Francisco will reconstruct eight flumes varying in length from 166 to 1,500 feet. These flumes are part of the Drum Canal that will transport water from Lake Spaulding to the powerhouse forebay reservoir nine miles away. Enlargement of the remainder of the canal is being done by PG&E General Construction Department forces. Darkenwald Construction Company, Sacramento, will enlarge the forebay by work which will increase its capacity from 444 to 590 acre feet. In addition, Darkenwald will construct a small portion of the 6, 200-foot penstock which will carry the water 1,372 feet from the forebay to the powerhouse turbine. T he powerhouse will be operated with water stored by Nevada Irrigation District's Yuba -Bear Project, which is being constructed through a partnership agreement between PG&E and NID. of this month, Removal of construction equipment and cleanup of this project site, along with completion of minor items, remain, This project segment is listed as 98 per cent complete. The Dutch Flat Flume on Bear River isnow80 per cent complete and the overflow spillway adjacent to the intake was concreted during the period. Installation of the Stump Canyon Siphon is 40 percentcomplete, All powerhouse concrete has been placed, the turbine and pressure regulator have been set, assembly of the. generator is under way and “assessory equipment is being installed. The Dutch Flat powerhouse project is listed as 77 per cent complete. The Chicago Park Power House New State Highway Construction Crews Press For Yuba-Bear Project Completion project is now 80 per cent complete. Float wells are being installed on the Chicago Park flume, the communications pole line was erected and the three overflow sections were completed. At the powerhouse site, the spiral case for the turbine was embedded, pedestal forms are being constructed and accessory equipment installed. The Faucherie Dam in the mountains is listed as 99 per cent complete and activity centered on repair of storm damaged roads and burning of debris piles. Rollins Dam on Bear River and Scotts Flat Dam on Deer Creek are listed as 100 per cent complete. Map Goes To Press The format for California's first official highway travel map has been approved by Department of , Publi¢ W orks DirectorJohn Erreca, In addition to the standard features most highway maps have in common, the new map will be augmented on the cover with 25 photographs and a text aimed at providing California drivers with timely information. One such section is devoted to safe driving tips and another describes the function of the California Highway Patrol and outlines the easiest way in which a driver can obtain emergency assistance. A brief description of the State traffic laws is included, State Approves Completed Paving At The Local Fair The paving project of roads, walks, and entrances to buildings at the Nevada County District Fairgrounds is completed, has been inspected by the state engineers and accepted according to fair Manager Malcolm Hammill, The shoulders on the picnic area road will have to cure for a few days, but this area should be open soon. The board of directors and Manager Hammill are very proud of the entire project and believe that practically all dust has been eliminated and the smooth surfaced pavement will make easier walking for the hundreds of people who will visit the Fair on California's most beautiful fairgrounds, Fair dates this year are August 26th-27th-28th-29th, less than two months away. Also explained are the freeway and expressway complex, and scenic highway systems. California's pay-as-you-go highway construction program is outlined ina brief statement that pertains to licenses and to the taxes highway users pay. A message from Governor EdmundG, Brown, typical scenes of California highways and inset maps of the Los Angeles and San Francisco areas complete the cover side, The map proper will identify freeways and other divided highways with symbols, California elements of the. National System of Interstate and Defense Highways that have not yet beenconstructed also will be shown. The locations—of mountain passes and a symbol to indicate whether they areclosed by winter snows and the whereabouts of ski areas willbe of interest to winter drivers, State parks will be identified, along with information pertaining to the availability of camping sites; National parks and monuments will be outlined by boundaries. Roadside safety rests and standard roadside rest areas will be shown. All California missions and many of the colleges and universities will be identified. Some of the State's more prominent unofficial points of interest will be made easier for drivers to find. The map will be obtained for the Department of Public Works by the State Purchasing Office. The first delivery will be made in October with the thought that copies will be available in time for delivery to high schools desiring to use the map as a training aid in driver education classes.
