L.A. RIVER FLOOD
Los Angeles River headwaters, here at the confluence of Arroyo Calabasas and Bell Creek. Calabasas Creek begins near the Leonis Adobe with the merging of Dry Canyon Creek from the Santa Monica Mountains and McCoy Canyon Creek from a Simi Hills watershed.
HISTORYCity engineer William Mulholland once described the Los Angeles River as a beautiful little stream with willows on it's banks. But periodic flooding was an ongoing danger to the Los Angeles basin, espacially during the rain seasons of 1825, 1832, 1861, 1884 and 1914
so today the Los Angeles River is a 60-mile cement-lined flood channel leading from Canoga Park to the Long Beach Harbor. The fall of the river was between 16 and 23 feet per mile and his velocity and destructive power was carrying away orchards, vineyards, sheds and agricultural fields.
Construction begun in 1938 and today 40% of the river is dammed, with the Sepulveda Flood Control Dam and the HANSEN DAM as main barriers to the stream's flow.
Today environmentalists propose a rehabilitation of the banks with nature trails and parks as recreation area for all.
