1-2-3-4 I Declare A Water War (LA's Water)

Hot town!  Summer in the city is here!  Cool down with this month's episode on the harnessing of the LA River as the city's water source in the early days (:15) and the creation of the Owens Valley aqueduct and the ensuing water wars in the slightly less early days (:55).  Chinatown references need not apply.
