Santa Anita Dam
[2] The dam is situated in the steep San Gabriel foothills, north of Sierra Madre and Arcadia.The viewing window for the dam is very short, only about a half-mile; the access road which runs down into the canyon from Santa Anita Canyon Road is closed to the public.However, the First Water trail, which leads downstream from Chantry Flat along the creek, is said to provide access to the reservoir.Since the 1990s the maximum allowed storage of water has been restricted, to ensure that the dam will not collapse due to seismic instability.This has partially caused rapid silting of the reservoir and sediment removal was started in mid-2009.
