Title:  Crews and Camps During Aqueduct Construction

Description:
O. W. Peterson Camp at Lone Pine - – Named after a solitary pine tree that once stood at the mouth of Lone Pine Canyon, this small California town's roots stretch back into the Old West -- and Hollywood's Wild West, too. Back in the mid-1800's, the town of Lone Pine was founded to supply local miners with provisions. Farmer and ranchers followed soon after, and after that, the Carson Colorado Railroad pulled into town. Today, the only part of pre-1870 Lone Pine that's still standing is a portion of an old adobe wall that stands behind the local flower store, "La Florista". A few miles to the east, you can also wander among the decaying ghost-town ruins of Cerro Gordo.

The town is located in the Owens Valley, near the Alabama Hills.

On March 26, 1872 a very large earthquake destroyed most of the town and killed 27 of its 250-300 residents.

Much of the local economy is based on tourism, as the town is between several major tourist destinations, such as Mount Whitney, Sequoia National Park, Kings Canyon National Park, Mammoth Mountain, Death Valley National Park, and Yosemite National Park; many motels line the main road through town. The Manzanar National Historic Site (formerly the Manzanar War Relocation Center), a Japanese American internment camp (concentration camp) during World War II, is located on Highway 395 north of Lone Pine and south of Independence. Manzanar (which means “apple orchard” in Spanish) is the best-known of the ten camps in which Japanese Americans, both citizens (including natural-born Americans) and resident aliens, were imprisoned during World War II. Manzanar has been identified as the best preserved of these camps by the Untied States National Park Service which maintains and is restoring the site as a U.S. National Historic Site. The Alabama Hills Recreation Area are located just west of town, on the road to the Whitney Portal which offers access to Mount Whitney.

On the way to Whitney Portals and the Alabama Hills visitors will pass over the two Los Angeles Aqueducts, the First Los Angeles Aqueduct (completed 1913) and the Second Los Angeles Aqueduct (completed 1970). These aqueducts traditionally have supplied Los Angeles with about half its water, some 450,000 acre feet (560,000,000 m³) a year. Because groundwater pumping continues at a higher rate than the rate at which water recharges the aquifer, the result is a lone-term trend of desertification in the Owens Valley. The Sierra Nevada range and the Inyo Mountains dominate the views from the town.

The picturesque Alabama Hills lie to the west of Lone Pine. Their unique appearance has attracted many film companies over the years to Lone Pine for filming westerns. The hills were named in 1862 by Southern sympathizers commemorating the victories of the Confederate ship Alabama.

The Lone Pine Indian Reservation is home to persons of Paiute, and Shoshone lineage and is a Federally recognized tribe. The tribe is the most southern band of Northern Paiutes who were sedentary to the valley due to the suitable climate and abundant food supply. These people have been living here for several thousands of years. The reservation is along the south side of town on both sides of US395.

Title:  Fairmont Reservoir

Photo Date:  January 16, 1918

Description:
Construction of Fairmont Reservoir

The work on the Fairmont Reservoir has been under the direction of the engineer in charge of the construction of the Elizabeth Tunnel. As the lining of the Elizabeth Tunnel is now nearing completion the remaining construction work on the Fairmont Dam and other features of the reservoir have been placed in charge of the division engineer of the Mojave Division.

Briefly stated, it is intended not only as a safeguard in the shape of a storage supply 200 miles from the intake, but also as a means for regulating the hourly fluctuation of water through the power plants located below, to meet peak load conditions. The capacity of the conduit into this reservoir is 420 cubic feet per second, but the outlet tunnel from the reservoir to the power plant has a capacity of 1,000 cubic feet per second. This will permit the discharge of this large volume of water in the few hours of the day during which the maximum demand exists for electric energy, and the decrease of the flow of water to a minimum amount during the night hours when the demand for power is relatively small. The mean discharge from the reservoir during the 24 hours of the day will be approximately 400 cubic feet per second. The excess capacity, above 400 second feet, of 20 cubic feet per second entering the reservoir is to enable the accumulation of water in this reservoir in case it should become necessary to draw it down and afterwards recover the available supply in the reservoir without interfering with the power output.

The capacity of the Fairmont Reservoir at the 3,035 feet elevation is 7,620 acre feet. The dam will have a maximum center height of 115 feet and will contain 607,114 cubic yards. It will be built of earth with a concrete core-wall. The excavation from the northern half of the Elizabeth Tunnel has been put in the outer toes of the dam and amounts to 84,000 cubic yards. The core-wall will be carried up to the full height of the dam. There will be an outlet tower and regulating gates from the reservoir into the north end of the Elizabeth Tunnel. The Fairmont Reservoir will be to the advantage of both the Aqueduct Bureau and the Power Bureau and will be paid for jointly by them on a ratio which has not yet been decided upon.

The Fairmont Tufa Mill is under the direction of the division engineer for the Mojave Division. The building of this mill has cost $26,666. Up to date there has been manufactured a this plant 218,755 barrels of tufa cement, and there is still 100,000 barrels to grind. The saving resulting from the use of the Fairmont tufa cement is 97 cents per barrel. The purpose of this tufa mill has been distinctly one of economy, although the product that has been turned out is as satisfactory as either the Colton, Riverside or Monolith Portland cement. The mill is located on the line of the work about 20 miles from the railroad, and by this regrinding process about 75 cents per barrel has been saved in transportation charges alone.

A very satisfactory practical test has been made of the tufa cement in the building of 6 reinforced concrete siphons with this product. These siphons are 10 feet in diameter with a 9-inch shell, and are built for heads up to 75 feet. All but one of these pipes has been filled with water now for over 6 months, and has with-stood this pressure without leakage or injury. The entire water load apparently is being carried by the concrete and none of it by the reinforcing. Also the Elizabeth Tunnel, which is 26,870 feet long, has been entirely lined with tufa concrete. Some of this ground is very heavy, requiring close timbering with 10 by 10 sets. This concrete lining is satisfactory, and no cracks have been discovered in the entire length of the tunnel.

A characteristic of the tufa cement, when made into standard sand briquettes, is that while it is slow in getting its initial hardness and requires from six to ten days to attain the strength of standard Portland cement, thereafter it continues to grow in strength, and exceeds the straight Portland cement. This hardening process continues for over a year’s time.

Title:  Crews and Camps During Aqueduct Construction

Description:
Kitchen crew--Mojave Division Camp

November 30, 1908 – The Mojave Division extends from a point known as Pinto, where the Aqueduct leaves the rough mountain district of the Jawbone and enters upon the Mojave Desert to the north end of crossing of Cottonwood Creek in Antelope Valley, the total length of the Division being 148,750 feet, all of which is canal in open country of easy construction.

The grade elevation of the north end of this Division is 3,171.04, and at the south end 3,118.94, thus providing a fall of 52.10 feet. Telephone lines have been built, roads constructed and a water supply furnished under pressure along the entire line of the Aqueduct.

At the present time there are two steam shovels at work in this Division, and an Austin excavator is being erected. Steam shovel No. 1 began work in September, 1908. Four thousand five hundred twenty-five feet of canal have been excavated and 4,032 feet lined. The shovel is of the Marion Model 20 type with an extra long boom. Shovel No. 2 began work in October and is a Marion No. 40 type with an extra long boom. Shovel No. 2 is working from the Southern Pacific Railroad north, and has excavated 2,947 feet of canal and 1,685 feet have been lined. A progress of 2,000 feet a month can be made with each of these machines. The Austin excavating machine is being erected at a point about ten miles from Mojave. This machine has a template designed to be an exact section of the ditch and the cutting buckets are arranged in such a manner that the exact section of the canal will be excavated.
