Back in 1912, 74-year-old Whistling Dick drove a team of 52 balky mules as he labored with hard working crews building one of the toughest sections of the Los Angeles Owens River Aqueduct in the Mojave Desert – the spectacular jawbone Siphon, a giant roller coaster of a pipeline. Early postcard depicting “Whistling Dick”, a 76 year old muleskinner who worked on the aqueduct; postcard was loaned for copy purposes by Department of Water and Power retiree Ed Fleming of Mojave (June 1971). Fleming stated that the picture shows Dick Wright mounted on the left wheel mule holding the jerk line, and his two swampers are atop the load of pipe. Roderick MacKay had general supervision of the operation of the cement mill and of the selection and advisory of the heavy mechanical equipment. E. F.Scattergood was Electrical Engineer in charge of construction of the power plants.

The overlapping of the supply operational areas provides an opportunity for the responsible agencies to coordinate their efforts should any of the aqueducts become damaged from a seismic (or other) event. Given the specialized nature of tunnel repairs, a workshop convened industry experts in tunnel engineering and construction to identify repair options and estimate repair durations. Participants concluded that, with preevent planning, design, and upgrades, repairs to -Whitewater Tunnel No. 2 could be completed within 6 months. San Francisquito Canyon Power Station 2 & St. Francis Dam Memorial MarkersAbout 5.2 miles into San Francisquito Canyon Road is LADWP's Power Station 2, a hydroelectric power plant, and one of 14 in LADWP's Aqueduct system.

This timeframe is longer than previously anticipated, as described in the following section, revealing new challenges for regional response and recovery efforts (Davis 2009, 2010; Davis and O’Rourke 2011). The three aqueduct systems that import water to Southern California are the California Aqueduct as part of the State Water Project (SWP), -Colorado River Aqueduct (CRA), and Los Angeles Aqueduct (LAA) (figure 1). The independently owned and operated systems work in conjunction to supplement local water resources and meet the demands of the region.

Regrinding mills were also built and operated by the city at the tufa quarries. To move 14 million ton-miles of freight, the city contracted with Southern Pacific to build a 118 mile long rail system from the Monolith mills to Olancha. In my opinion, Cascade Canyon is one of the premier mineral collecting localities in the United States. Not only does it boast spectacular corundum crystals, but it also is one of only three places in the United States where one can find lapis lazuli. Lau brings more than 30 years of experience in the outdoor industry to his role at Cascade Designs. Before moving to the brand, he served in key account and national sales management roles with Yeti Cycles, The Timberland Co., The North Face, and more.

F. J. Mills was Division Engineer of the Grapevine division, consisting of tunnels and pressure pipes. C. H. Richards was in charge of the construction of the covered conduits and tunnels in the Rose Valley and Little Lake divisions. The LADWP is also undertaking other seismic improvements along the LAA and a detailed investigation to characterize the SAF at the Elizabeth Tunnel crossing. These efforts will inform the planning to engineer a solution for the potential maximum fault offset (Lindvall et al. 2018). Eastern California MuseumThis museum (also built on LADWP property), which focuses on the regional history of the Eastern Sierra, has an exhibit on the construction of the L.A.
A Self-Guided Tour of the Los Angeles Aqueduct
It is an hour’s ride from Los Angeles to Victorville on Highway 395, but Adelanto Mine is one of the most visited digging sites in the high desert of Southern California. You many unearth corundum crystals, quartz minerals, fuchsite and other fossils. There is ample parking off the main road as the main path to the digging site is well identified with signage. Collectors gather at several digging sites just outside the city of Agoura. Featuring extra warmth in the torso and feet, women-specific Therm-a-Rest® ProLite™ Series mattresses are designed to meet women’s frequent requests for a warmer lightweight mattress.
In 1917, The Bureau of Los Angeles Aqueduct sought to build a holding reservoir to regulate flow and provide hydroelectric power and storage in case of disruption to the aqueduct system. The resulting St. Francis Dam was completed in 1926 and created a reservoir capacity of 38,000 acre-feet (47,000,000 m3). On March 12, 1928, the dam catastrophically failed, sending a 100-foot high (30 m) wall of water down the canyon, ultimately reaching the Pacific Ocean near Ventura and Oxnard, and killing at least 431 people. The resulting investigation and trial led to the retirement of William Mulholland as the head of the Los Angeles Bureau of Water Works and Supply in 1929.
Cascade Canyon offers a wide variety of rocks, minerals and crystals to all collectors. The Palos Verdes Peninsula’s cliffs are easy to find as you will travel along the main road to Pelican Cove near the water. To the eastern side of the cliffs, smaller, clearer barite crystals can be found.

Construction of the Los Angeles Aqueduct
It has been over 150 years since the last earthquake ruptured across locations of the SWP and LAA and over 300 years since the last rupture crossed the CRA location (Philibosian et al. 2011; Scharer et al. 2010). The LADWP and the area supplied by the LAA can also be supplied by SWP and CRA water. Eastern Sierra Interagency Visitor CenterMore than just an information center, this building features an interactive model of the L.A. Aqueduct system, a section of Aqueduct pipe and an exhibit on the waterway's construction. Information and passes on nearby Sierra Nevada hiking trails can be obtained here as well.
The former was where the Aqueduct's chief engineer William Mulholland told mayor Henry Rose, "There it is, take it!" at the opening ceremonies 100 years ago this week. The two aqueducts merge into one course and lead into the DWP's L.A. Aqueduct Filtration Plant on the south side of the 5 Freeway, where a chemical process consolidates dirt and impurities, and the water is cleansed through a six-foot bed of anthracite coal. As soon as 45 minutes later, Aqueduct water enters the city's water main system. Their favorite digging sites are located on the southern side of the flats.

The Therm-a-Rest® NeoAir air mattress redefines ultralight comfort for ounce-counters. Without added insulation, a patent-pending internal structure provides unrivaled air mattress warmth and stability with two inches of loft.
According to LADWP water works engineer Fred Barker, the unpressurized conduit must meander to follow the contour of the land and keep a steady elevation drop to allow the gravity-assisted water to flow. However, if you know where to look, you can see the outline of the concrete lid of the conduit on the ground, and see a few access structures. The San Francisquito Tunnels (which include the Elizabeth Tunnel) have a flow capacity of 1,000 cu ft/s (28,000 L/s)[33] and are large enough to handle the flow of both aqueducts. Once the combined flow reaches the penstocks above Power Plant #2, water is diverted into the Southern Section of the second aqueduct through the Drinkwater Tunnel to the Drinkwater Reservoir.
Aqueduct system in 1924 to store water in a three-mile-long reservoir, this dam broke on the night of March 12, 1928 due to unstable bedrock beneath the dam, flooding San Francisquito Canyon and killing around 600 people in the second-largest disaster in California history. The floodwaters reached the Santa Clara River and ended up in the Pacific Ocean five hours later. Accepting full responsibility, Mulholland ended his LADWP career because of the catastrophe. The LA Aqueduct brought water from the Owens Valley hundreds of miles away to a growing area in need of additional resources to sustain its people and their endeavors, helping spur an economy that today rivals that of many nations. A century later, this gravity-fed system continues to be a major source of water for Los Angeles — on an average year supplying 29% of the water needs for four million people.
