Santa Fe Dam and Flood Control Basin

As the San Gabriel River exits the mountains just north of the Fish Canyon Spreading Grounds, the river's channel changes from a V shape to a U shape (more of \__________/ than a true "u") as the topography changes from mountains to alluvial fan to flatlands. The Santa Fe Dam sits right at this transition zone on one of the many alluvial fans that spread out at the foot of the San Gabriel Mountains.

The Santa Fe Dam was yet another result of the Los Angeles County Flood Control Program.  Building started in 1941, but more floods and WWII delayed completion until 1949.  Unlike the Morris and San Gabriel Dams, this dam was not built to hold water continuously.  Instead, it is designed to hold back water during a flood event, protecting the inhabitants downstream.  When the danger is over, water can be released in a controlled manner.

In 1974 approval was given to use the area behind the dam as a recreation area, and the Santa Fe Dam Recreation Area was born.  The area contains a 70-acre lake that allows swimming and non-motorized boats, in addition to picnic areas and trails.  During late April through May, the Renaissance Pleasure Faire is held.
