Owens Dry LakeBy far the largest environmental impact created by the L.A. The opening of the Aqueduct caused its only inlet, the Lower Owens River, to dry up, turning what was once the second-largest lake in California into a dry lake bed. Since then, high desert winds have kicked up the dust from the heart-shaped lake bed to create one of the worst air-polluted locations in the entire United States. The LADWP was forced to implement dust mitigation measures in the form of limited flooding, irrigation, native plant growth, and gravel placement, which has since stemmed most of the dust pollution issues in the region.

Aqueduct and the subsequent Owens Valley Water Wars, featuring historic photographs and diagrams. On the museum's grounds, actual vehicles and equipment used in the construction of the Aqueduct are on display. Last year, during my first visit to the Owens Valley, I was able to not only experience the Aqueduct first-hand, but meet the very people who have been impacted -- both positively and negatively -- by its presence. Since then, I have made two more visits within the past year, learning more about the Aqueduct every time.

The National Park Service-run interpretive center and grounds are still worth a visit anyway for another great history lesson. The Cascade is a sleek design, exemplary of the Contemporary Series, that makes use of post-and-beam joinery and black pipe railings to give a modern industrial aesthetic to the home. The main room includes tall exposed timber ceilings with panoramic folding glass doors that can open up to the spacious porch, vastly increasing the space available in warm seasons. The scenery found on the pathway to the digging sites is quite breathtaking. So, every guest should expect to hike a portion of their journey to the digging sites. You will turn west off the 395 and travel a quarter of a mile on an unmarked road until you arrive at the property.
Influence on Los Angeles and the county
A major accomplishment to meet local emergency water storage objectives was the completion of -Diamond Valley Lake in 2000, which nearly doubled the available emergency supplies in Southern California. In addition, MWD may draw from water-bank agreements during an emergency, if necessary and available. Alfalfa FarmThis unusually verdant patch of farmland offers a small glimpse of what parts of the Owens Valley looked like before the Aqueduct. This particular patch hosts an alfalfa field, leased by farmers, and developed as one of the mitigation measures agreed to by the LADWP to address or minimize environmental damage created by groundwater pumping.
The revolutionary design allows direct inflation, eliminating the need for pumps or bellows. Filtering water becomes as easy as hanging a reservoir of water with the introduction of the Platypus® CleanStream™ Gravity Filter. With no moving parts, an ultra-efficient, hollow fiber membrane makes pump-free filtering possible by harnessing gravity to deliver 4 liters in just 2.5 minutes. Ushering in camping innovation, the MSR® Hubba™ 1-person and MSR® Hubba Hubba™ 2-person tents utilize a one-pole hub and swivel design to deliver the perfect combination of light weight and livability that make it the best-selling ultralight tent in the world. The inconveniences of filling and cleaning hydration storage systems are eliminated with the revolutionary Platypus® Big Zip™ reservoir. Featuring a first-ever wide-mouth opening, it allows for easy access to the reservoir for cleaning and filling.
California Isn't on Track To Meet Its Climate Change Mandates. It's Not Even Close.
An event like the ShakeOut Scenario could damage the tunnel at the fault crossing and shallow sections near the tunnel portals. MWD coordinates with its member agencies to set criteria for emergency storage, assuming that damage from a major SAF earthquake could render the aqueducts out of service for 6 months (MWD 1991). The objective is to ensure water supply and delivery to all member agencies during the outage. This objective allows MWD to provide 75 percent of member agencies’ retail demand under normal hydrologic conditions, supplementing local water production to avoid severe water shortages while the aqueducts are out of service. Independent studies based on the ShakeOut -Scenario noted that repairs to all three aqueducts would likely require more than 6 months.

It provides a realistic illustration of possible fault displacement and shaking throughout the region and useful insight into water supply impacts. In 2008 the US Geological Survey, along with many partners, completed a study of a plausible Mw 7.8 earthquake on the southern SAF (Jones et al. 2008) for use in the Great Southern California ShakeOut exercise (hereafter, the ShakeOut Scenario). Figure 2 shows the region, ruptured portion of the SAF (black), shaking intensity for this scenario, and how it affects the broad Southern California urban area (figure 1). The hypothesized Mw 7.8 earthquake has an epicenter at the Salton Sea and ruptures along a 300 km (190 mile) distance north to Lake Hughes (Graves et al. 2008; Hudnut et al. 2008). Jawbone Canyon "Siphon""Don't call it a 'siphon,'" says LADWP's Barker, "It's a 'sag pipe.'" However, the "siphon" terminology was a popular, if not accurate, description of the pressurized structure, in the era the Aqueduct was built. Without the use of mechanical pumps, gravity works the water down and back up again through water pressure and the width and thickness of the piping.

Many locals will trek to Shadow Mountain as it has become the ideal location in Los Angeles. Remember, the digging site is located on private property, so you will need to gain permission to rockhound before entering the site. Many prospectors begin their day by chipping away at the sedimentary rock formation found on the south side of the canyon.
The dam failure is the worst man-made flood disaster in the US in the 20th century and the second largest single-event loss of life in California history after the 1906 San Francisco earthquake. The format allowed the candid exchange of information and ideas among all participants. The LADWP is the second-largest employer in Independence, a town of some 600 people and the seat of Inyo county. In addition to providing electric power utilities to most of the area, LADWP crews also perform monitoring and maintenance tasks on the Aqueduct, groundwater pumps, dust mitigation efforts, and the Lower Owens River project. Recent CRA seismic vulnerability assessments identified the Whitewater Tunnel No. 2 as the most likely component of the system to sustain major damage from a strong earthquake on the southern SAF (MWD 2016; Weldon et al. 2014, 2016). The tunnel’s alignment closely parallels the SAF and crosses a splay of the fault.
Manzanar National Historic SiteThe place where over 10,000 Japanese Americans were interned during World War II also has a connection to the Aqueduct. The LADWP had begun pumping out Owens Valley groundwater into the Aqueduct in the 1920s, and farmers lacked water for irrigation, rendering the former apple-growing farm community of Manzanar (hence the name in Spanish) a ghost town by the end of that decade. In 1933 the LADWP purchased the area around Manzanar for water rights, and the U.S. Army had to lease 6,200 acres of DWP-owned land to establish the War Relocation Center in 1942.
Under Mayor Eric Garcetti, a strategic plan for the City of Los Angeles, Resilience by Design (Mayoral Seismic Safety Task Force 2014; Jones and Aho 2019, this issue), was developed, with specific recommendations for improving the seismic resilience of the Los Angeles water system. One key recommendation is to “create a Seismic Resilience Water Supply Task Force . With the LADWP, MWD, and DWR, in an effort to create a collaborative and regional approach to protecting the resilience of our water supply.” This recommendation was informed by the ShakeOut Scenario, previously mentioned studies of the regional water supply, and LADWP (2014). As part of the Mayoral Seismic Safety Task Force, the LADWP developed an internal water system resilience program (LADWP 2014, which made the same recommendation as Davis and O’Rourke 2011). A major SAF earthquake could have severe impacts on aqueduct operations, including the potential to completely disrupt all imported water supplies to Southern California until repairs can be made. The ShakeOut Scenario was used to enhance understanding of the effects of a Mw 7.8 event on critical infrastructure and identify the physical, social, and economic consequences.

MWD also owns and operates five water treatment plants and over 800 miles of pipeline to distribute water imported from the CRA or the SWP California Aqueduct East and West Branches to member agencies. Additionally, an interconnection between the LAA and MWD system can be used to supplement the portion of MWD’s service area that is normally supplied by the SWP West Branch with water from the LAA. The California Department of Water Resources (DWR) operates the SWP, the nation’s largest state-built water development and conveyance system. Placed into service in the early 1970s, the SWP provides water for 25 million residents, farms, and businesses statewide, including 19 million people in the Southern California urban area (figure 1) via the California Aqueduct’s East and West Branches.

Located in Bureau of Land Management-owned recreational land, the canyon is also a popular spot for camping and off-road vehicles. The newer Second L.A. Aqueduct can be seen across the mouth of the canyon. San Francisquito Canyon Power Station 1Built in 1917, this hydroelectric facility was LADWP's first power generation station. Fed by the Aqueduct penstock descending from the mountain above, generating 71,900 kilowatts of electricity.
