Rio Hondo (California)

The Rio Hondo ( Spanish: ''Río Hondo'', meaning "Deep River") is a tributary of the Los Angeles River in Los Angeles County, California, approximately long.U.S. Geological Survey. National Hydrography Dataset high-resolution flowline data

accessed March 16, 2011 As a named river, it begins in Irwindale and flows southwest to its confluence in South Gate, passing through several cities (though not the city of Los Angeles). Above Irwindale its main stem is known as Santa Anita Creek, which extends another northwards into the San Gabriel Mountains where the source, or headwaters, of the river are found.

Background

The Rio Hondo has sometimes been described as a second channel of the San Gabriel River. For much of its length, the rivers flow parallel to each other about two miles (3 km) apart. Both rivers pass through the Whittier Narrows, a natural gap in the hills which form the southern boundary of the San Gabriel Valley. Here, both rivers are impounded by the Whittier Narrows Dam, which the Army Corps of Engineers describes as, "the central element of the Los Angeles County Drainage Area (LACDA) flood control system". During major storms, the outlet works at Whittier Narrows Dam can direct water to either channel, or runoff can be stored.

The Rio Hondo and San Gabriel River have both been part of a revitalization program called the Emerald Necklace. The goal of this program is to create a "necklace" of parks and reclaimed wild spaces with the two rivers. They are connected by a narrow strip in Irwindale and by Whittier Narrows to give them the appearance of a necklace if viewed from above. The project garnered broad support from organizations such as the Sierra Club along with the governments of the many cities the rivers pass through.

Most of the Rio Hondo is a concrete-lined channel to serve its primary flood control function, but in two places the river flows over open ground: the Peck Road Water Conservation Park, and the Whittier Narrows Recreation Area. Large spreading grounds for water conservation surround much of the river, and its bike paths are very popular.

The river passes through the location of the Battle of Rio San Gabriel, fought on January 8, 1847, and which resulted in a U.S. victory. Although the battle was actually fought on the west bank of the present-day Rio Hondo near where it is crossed by Washington Blvd, the battle is named after the San Gabriel, which at that time flowed along these banks. A flood in 1867 caused the San Gabriel to change course, which it retains at present. The old San Gabriel was renamed the Rio Hondo after this flood. In Downey, California, the Rio Hondo was once known as the "Old River", because it was the old course of the San Gabriel River. The Old River School was named for it, and Old River School Road was named for the school. The "New River" is the present course of the San Gabriel River.

Legacy

The Rio Hondo College and Rio Hondo Preparatory School were named after the river.

In what is now the Bosque del Rio Hondo Natural Area, Marrano Beach was born on the riverfront property of El Rancho de Don Daniel, a Mexican land grant from the nineteenth century that had belonged the Repetto-Alvarado family, a prominent family of California land owners. El Rancho de Don Daniel encompassed riparian wetlands and ponds surrounding the Rio Hondo, which flowed year-round, and the seasonal Mission Creek. With few opportunities for respite after toiling in the fields, Mexican-American residents of the local barrios cultivated recreational lifestyles around this section of the river and embraced it as a bucolic resource for community and family activities.
