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 Transit users can exit the G Line at either Balboa station or Woodley station.
