Sepulveda Dam

The Sepulveda Dam is a project of the U.S. Army Corps of Engineers designed to withhold winter flood waters along the Los Angeles River. Completed in 1941, at a cost of $6,650,561 (), it is located south of center in the San Fernando Valley, approximately eight miles east of the river's source in the western end of the Valley, in Los Angeles, California.

Sepulveda Dam, along with Hansen Dam located in the north San Fernando Valley, was constructed in response to the historic 1938 floods which killed 144 people. Sepulveda Dam was placed at what was at the time, the current edge of the city. East of the dam the river was crowded into a narrow bottom by the city's growth. One legacy of Sepulveda Dam is its flood control basin, a large and undeveloped area in the center of the Valley, used mostly for wildlife refuge and recreation. But another legacy of the 1938 Los Angeles River flood was the post-World War II channelization of all the Valley's dry washes, which along with the post-World War II rapid suburbanization left the Valley with hot, dry, concrete-lined river bottoms instead of greenbelts. Although now, in part, these are being devolved as interconnecting bike paths.

Behind the dam, the Sepulveda Basin is home to several large recreation areas including Woodley Park, a model aircraft field, The Japanese Garden, a wildlife refuge, a water reclamation plant, and an armory. The Basin is kept free of urban over-building so that water can build up there during a prospective hundred-year flood.

It is an often-used location for films (such as ''Escape from New York''), music videos (such as '' BTS' Kinetic Manifesto'' and Keedy's ''Save Some Love''), and car commercials.

History

When the 1914 flood caused $10 million in damages to the developing basin areas, a public outcry began for action to address the recurring flooding problems. During the following year, the Los Angeles County Flood Control District was formed. Some of the early flood control efforts included smaller areas of channelization and the planning for needed reservoirs. Taxpayers approved bond issues in 1917 and 1924 to build the first major dams. However, they were not willing to provide enough funding for the much needed and substantial infrastructure downstream of these dams. After two more destructive floods in the 1930s, most notably the 1938 flood, federal assistance was requested. The Army Corps of Engineers took a lead role in channelizing the river and constructing several dams which would create flood control basins behind them. Channelization began in 1938, and by 1960, the project was completed to form the present fifty-one mile engineered waterway. Included in this work were Hansen Dam, completed in 1940 and followed by Sepulveda Dam in 1941. In 1973, Burbank Blvd was built through the Sepulveda Basin, Woodley Ave was also built in the recreation area in 1975.

For 28 years the Sepulveda Dam did its job without incident until 1969 when the Los Angeles River overflowed its banks causing millions of dollars in damage. In 1988 the Los Angeles River's banks were raised to avoid another incident. In 1994 a hundred-year flood occurred in the Los Angeles River. The dam was restored and went without incident for another 11 years until the Los Angeles River again overflowed its banks in 2005.

During the 2028 Summer Olympics, the area around the dam will host Canoe Slalom, Equestrian and Shooting.

Access

Lake Balboa Park

Lake Balboa Park, also known as Anthony C. Beilenson Park, is an park and water recreation facility with boat rentals and fishing. Lake Balboa is a lake filled with water reclaimed from the Tillman Water Reclamation Plant.City of Los Angeles Parks Department: Lake Balboa Park (Anthony C. Beilenson Park)
It also has barbecue pits, children's play area, picnic tables, and covered picnic pavilions. There are many Flowering cherry trees (''Prunus serrulata'' 'Pink Cloud') in the park.

The Balboa Station on the G Line is located at the north end of the park, at Balboa Boulevard.

Sepulveda Basin Wildlife Reserve

The Sepulveda Basin Wildlife Reserve is at the southeast end of the Sepulveda Flood Control Basin and Recreation Area.SepulvedaBasinWildlife.org: Sepulveda Basin Wildlife Reserve website
/ref> It has two sections, the North Reserve and South Reserve, located north and south of Burbank Boulevard. Both have nature paths and hiking trails.Sepulveda Basin Wildlife Reserve Trails Map
/ref> Access and parking are in eastern Woodley Park near to the Tillman Water Reclamation Plant, or from Burbank Boulevard east of Woodley Avenue.

Haskell Creek flows through the nature preserve, and there are several wildlife ponds. Over 200 species of birds have been seen in the basin. Many, attracted by the water, gather here during fall and spring migrations. The Sepulveda Basin Wildlife Reserve is an ongoing habitat restoration project, with locally native California plants.

Sepulveda Dam Recreation Area Bike Path

The Sepulveda Dam Recreation Area Bike Path is a bicycle path route looping around the recreation area.L.A. Bike Paths.com: Sepulveda Dam Recreation Area Bike Path
/ref> This “very popular bike path” runs from Victory Boulevard near Interstate 405, westward to White Oak Avenue, south on White Oak to Burbank Boulevard, east on Burbank to Woodley Boulevard, and north on Woodley returning to Victory Boulevard. Public access is continuous along it. The ride features no steep or sustained hills with a maximum grade of no more than two percent.

A shorter route heads south on Balboa Boulevard, which crosses a natural stretch of the Los Angeles River that lined with native Arroyo willows, California sycamores, and other California native plants.

The bikeway “cruises around the Balboa Sports Center and several golf courses, and has several open areas with spectacular views of into the mountains to the north and east.”

The loop sections along Victory and Burbank can be frequented by joggers. The bike path can seasonally have burr-bearing weeds, which may cause flats in less durable tires. The Apollo II Model Airplane Field is visible from the path.

There is ample free parking available in the public park, sports field, and/or golf course parking lots on Burbank, Woodley and Balboa Boulevards.
