concludes at LA Aqueduct Intake Just the Fax Ma am Just the Fax from LADWP website The Story of the Los Angeles Aqueduct In 1913 the City ofLos Angeles completed construction of the rst Los Angeles Aqueduct This is the story of how the dream of a few farsighted people at the tum of the 20th Century became a reality Follow the links below for details on how the Los Angeles Aqueduct was conceived and built quotThe City Owns its Waterquot From the time that Los Angeles was rst founded in 1769 the small settlement had depended upon its own river for the city grew those in charge of supplying the growmg population with water knew the small meandering river could not meet future demands A New Supply William Mulholland an immigrant from Ireland went to company at the age of 31 Mulholland began to search for a new water supply The Owens River Valley In 1904 Fred Eaton and J B Lippincott traveled to Yosemite Valley on a family camping trip They crossed the Sierra at Tioga Pass and headed south to Bishop for supplies and eventually back to Los Angeles through the Owens Valley During that trip Eaton began making plans that would bring water to agrowing city and launch a long con ict quotThe Owens Valley is the Only Sourcequot Eaton convinced Mulholland that the Owens River could provide Los Angeles with a reliable source ofwater The Last Spike is Driven Eaton visited the Owens Valley in 1905 and began to purchase land for the City ofLos Angeles He gave the impression that he was working for the US Reclamation Service on apublic irrigation project angering local residents when they discovered he was buying land and water rights for Los Angeles A Hundred or a Thousand Fold More Important A er securing the land and water rights the Board of Water Commissioners needed to obtain the money from Los Angeles residents and legal rights from the Federal Government to construct the aqueduct A bond measure to pay for the construction passed in Los Angeles by a 10 to 1 39n A er much debate in the House of Representatives President Theodore Roosevelt decided that Los Angeles should have the rights to the Owens River water Construction Begins Construction on the Los Angeles Aqueduct began in 1908 Workers from all over the world came to work at highpaying jobs thatwould last for several years World Record dig eight feet of tunnel per day at each tunnel end for a total of 16 feet per day Crews dug more than 22 feet per day while constructing the fivemile Elizabeth Tunnel They nished the tunnel 20 months earlier than the Board39s estimate of ve years quotThis Rude Platform is an Altarquot At the dedication of the Los Angeles Aqueduct on November 5 1913 Mulholland told the thousands of people attending the ceremony that they were there to dedicate the Aqueduct to quotyou and your children and your children39s children for all time quotWhoever Brings the Water Brings the Peoplequot Once Los Angeles had a reliable water supply it began to grow dramatically However Owens Valley residents began to ght the City39s water export Confrontations escalated to several dynamitings of the Aqueduct To secure its water rights the City began to purchase extensive tracts of land in Ow s alle The Colorado River A Regional Solution As Los Angeles continued to grow Mulholland began to look for a way to bring Colorado River water to meet the City39s needs The Mono Basin Project After World War II the City began the Mono Basin Project as away of providing a larger and more dependable ow in the Los Angeles Aqueduct Four of Mono Lake39s seven tributary streams Lee Vining Parker Walker and Rush Creeks were tapped for export to Los Angeles through an 11mile tunnel Crowley Lake and Grant Lake were also built as part of the Mono Basin Project A Second Aqueduct The challenge to supply water to Los Angeles continued to press Because the capacity of the Los Angeles Aqueduct was limited the Citywas unable to take its full entitlement from the Mono Basin The California State Water Rights Board urged Los Angeles to take steps to develop its full entitlement or risk that the water might be granted to others To increase the Aqueduct capacity a second aqueduct was built from Haiwee Reservoir in Southern Inyo County to Los A Shared Resource The completion ofthe SecondLos Angeles Aqueduct in 1970 and the City39s plans to augment the Aqueduct ow wi Owens Valley groundwater prompted renewed local protests Inyo County led suit against Los Angeles under the new California Environmental Quality Act seeking an Environmental Impact Report on new aqueduct In 1984 er years of disagreements and court hearings Inyo County and Los Angeles entered into an Agreement to produce a EIR together Water Quality With Los Angeles growing at a rapid pace not only the availability ofwater but also the quality ofwater became more important at the last part of the 20th century Los Angeles built a ltration plant in 1986 and continues to monitor and improve water quality from its three sources Water Conservation gallons per day by the mid198039s about half ofwhat was used in unmetered cities such as Sacramento The City continues to emphasize and improve its programs through many innovative approaches that have made Los Angeles a water conservation leader in the Nation Water Reclamauon Reclaimed water is proving to be an excellent method of providing additional water to Los Angeles in an environmentally responsible manner Sharing the Vision Mulholland truly had a vision when he looked to the Eastern 39erra and envisione an aque uct to bring water to a growing city Los Angeles has become the nation39s second largest city because of his decision to find another reliable water supp y RealTime Gauging Data from the LADVV39P website on April 12
