Photograph of the water wheel near Elysian Park which raised water from the Zanja Madre that flowed to a reservoir in the Pueblo, ca.1870. This wheel was shipped from San Francisco and erected at a point just north of the Southern Pacific Railway yards at Elysian Park. The wheel raised water 36 feet from the Zanja Madre and the water flowed through wooden flumes to a reservoir located at the Los Angeles Plaza. The wheel itself had paddles 6-feet wide to each of which was fastened a 15-gallon bucket. Agricultural tracts visible in the background.
