This raises an interesting point: how come LA drains Owen's but San Fran fills Hetch Hetchy? Not a rhetorical question.
Hetch Hetchy stores water that is sent elsewhere for consumption at a different rate and time than it collected. Owens Lake consumed water by evaporation. That's why it was a pool of brine retaining the salts that entered it. It grew as big as it needed to be to evaporate the water that entered it. Its been thousands of years since it received enough water to make it overflow, as it once did, down through Fossil Falls.
