there are three sources for la water:
60% comes from the eastern sierra to la through the la aqueduct system
15% san fernando groundwater basin
25% metropolitan water district's colorado and feather river supplies

as arizona reduces our booty from the colorado river, mwd is going to search for alternative northern california 'supplies' through the state water project! wahoo!

so, since 'most' of my water comes from the eastern sierra, i have created a treasure map that shows just that. (except i don't have to go looking for treasure, it comes right to me!)

my drop of water melted from a snow pack in the eastern sierra, which flowed down into a tributary to mono lake. from there it entered the almost 100 year old los angeles aqueduct. completed in 1913, the first la aqueduct 'taps' into water of the mono basin and owens river valley and transports it over 200 miles to los angeles. the construction of this aqueduct created a violent conflict between the owens river valley and la. but don't forget the second aqueduct, completed in 1970 that starts at the haiwee reservoir, one of the 105 reservoirs along the aqueduct system. both aqueducts cumulate in the los angeles reservoir. the water then goes through the los angeles filtration plant, which uses ozone and rapid rate deep bed filters to treat up to 600 gallons of water a day. the plant also fluoridates the water.

then, the water flows through various underground pipes and out of my faucet... hurray!
