The Echo Park Lake Dam is back in the spotlight after being forgotten for many decades. The last time the dam, which is buried near the south end of Echo Park Lake, actually made news was in 1891. Back then, the city’s health inspector expressed concern that the dam could fail, sending a wall of water down the Arroyo de los Reyes, or what is now roughly the path of Glendale Boulevard.
A few months later, the city agreed not to raise the water level behind what was then Reservoir No. 4 as part of a deal to turn it into a city park.
