In 1908, construction of the Los Angeles Aqueduct began under supervision of the Bureau of Los Angeles Aqueduct department’s Chief Engineer William Mulholland. The Los Angeles Aqueduct carries water from the Owens River and delivers it to the Los Angeles metropolitan area. After the Los Angeles Aqueduct’s creation, many engineers considered it to be the greatest engineering creation second to the Panama Canal. It took roughly five-thousand workers and five years to complete this four hundred and nineteen mile long twenty-three million dollar project. The Los Angeles Aqueduct wasn completed on November 5th, 1913. On that day, forty-thousand people gathered to watch the arrival of water from the Own Valley.
