Castaic Lake was not a replacement for the St. Francis Reservoir. The St. Francis Reservoir stored water brought into Los Angeles County by the City of Los Angeles via the Owen Valley Aqueduct from Owen's Valley which gets its water from the eastern slopes of the Sierra Nevada mountains. Bouquet Reservoir serves that function today. Castaic Lake has water which was brought to Los Angeles County via the State Water Project which does not come from the Owen's Valley and is not operated by the City of Los Angeles but rather comes from the Central Valley which receives its water from the western slopes of the Sierra Nevada mountains.
