[3] This saves the city of Los Angeles about $2,250,000 annually due to the cost difference between local and imported water.

[4] Because of the small storage capacity of the reservoir relative to the size of its watershed, frequent dredging is required to remove sediment from behind the dam.

[7] During the Los Angeles flood of 1938, the dam was able to stop a huge debris flow of boulders and uprooted trees, sparing much of Sunland, Tujunga and Glendale from destruction.

[3] In 1976, the dam was recognized as in danger of failure from earthquakes (the San Andreas Fault runs nearby) and the reservoir's level was temporarily restricted to about 25% of capacity.

[8] In 2008 the Los Angeles County Flood Control District began a project to rehabilitate the aging structure.
