River Course
The watershed begins at Red Box Saddle in the Angeles National Forest near Mount Wilson in the San Gabriel Mountains. As it enters the urbanized area of the watershed, the Arroyo Seco stream flows between La Cañada Flintridge on the west and Altadena on the east. Just below Devil's Gate Dam, the stream passes underneath the Foothill Freeway; at the north end of Brookside Golf Course the stream becomes channelized into a flood control channel and proceeds southward through the golf course.
The Arroyo Seco goes through Pasadena, with the Rose Bowl and Brookside Park in it. The Arroyo Seco stream, which is fed by a 46.7 square miles (121.0 km2) watershed, helps to replenish the Raymond Basin, an aquifer underlying Pasadena that provides about half the local water supply. This is one of two major streams that capture rainfall and storm water in Pasadena, the other being Eaton Wash on the eastern side of the city, a tributary of the Rio Hondo watershed.
The Arroyo Seco proceeds on, passing under the Ventura (134) Freeway and the Colorado Street Bridge, and crosses the Raymond Fault at the southern boundary of Pasadena at the San Rafael Hills. The channel continues along the western boundary of South Pasadena, then into northeast Los Angeles flowing southeast of the Verdugo Mountains and Mount Washington.
The Arroyo Seco then proceeds through the Los Angeles neighborhoods of Highland Park, Cypress Park, and Montecito Heights. It ends at the confluence with the Los Angeles River near Elysian Park, north of Dodger Stadium and Downtown Los Angeles.
The Arroyo Seco Parkway, or Pasadena Freeway, parallels the channelized Arroyo Seco from South Pasadena to the Los Angeles River.

Famous quotes containing the word river:
“At sundown, leaving the river road awhile for shortness, we went by way of Enfield, where we stopped for the night. This, like most of the localities bearing names on this road, was a place to name which, in the midst of the unnamed and unincorporated wilderness, was to make a distinction without a difference, it seemed to me.”
—Henry David Thoreau (1817–1862)
