Spreading grounds beside the Rio Hondo in Pico Rivera, California

The Rio Hondo (Spanish translation: Deep River) is a tributary of the Los Angeles River in Los Angeles County, California, approximately 20 miles (32 km) long. 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).

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 Whittier Narrows Dam can direct water to either channel, as well as store runoff.

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 in 1847, and which resulted in a U.S. victory. Although the battle was actually fought on the present day Rio Hondo, 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.

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

Simple English

The Rio Hondo (Spanish for "deep river") is a river in Los Angeles County, California. Its official beginning is at a reservoir called the Whittier Narrows Reservoir; and it flows 20 miles (32 km) southwest to the Los Angeles River. Notably, the Whittier Narrows Reservoir is also fed by the San Gabriel River, and water can be released into either river. Therefore, the watersheds of the Los Angeles River and San Gabriel River are connected by the Rio Hondo.

Most of the Rio Hondo is lined with concrete, but there are two places the river is free-flowing. These are the Peck Road Water Conservation Park and the Whittier Narrows Recreation Area. Eaton Wash is a tributary to the Rio Hondo.
