Santa Fe Dam Recreation Area, Regional park in Irwindale, California, US.

Santa Fe Dam Recreation Area is a county park in Irwindale, in the San Gabriel Valley, built inside the Santa Fe Dam, a flood-control dam on the San Gabriel River that is dry most of the time. Its 70-acre lake, held back by the river, allows year-round fishing and non-motorized watercraft, with seasonal swimming. The San Gabriel River Bike Trail runs through the grounds and traces the dam rim east of the flood basin, reached from Azusa Canyon Drive.

The dam was built in the middle of the 20th century to manage flooding along the San Gabriel River and protect nearby communities. The surrounding land had been shaped by gravel mining operations for years before it became a recreational area.

The Santa Fe Dam Nature Center, run by the San Gabriel Mountains Regional Conservancy, focuses on the plants and wildlife of the San Gabriel River's alluvial fan. Its Saturday programs, from 10 AM to 1 PM, include nature and bird walks, insect identification and Tongva cultural history sessions.

The park is best visited on warm days when most activities are available, and arriving early helps secure good parking and seating near popular spots. Bring sunscreen and water, as shade can be limited in some areas around the lake.

The park hosts the annual Renaissance Pleasure Faire of Southern California, moved here in 2005 from Glen Helen Regional Park in Devore. The fair was founded by Phyllis Patterson and a group of students and is credited as the originator of modern Renaissance fairs, first held in Agoura, California.
