If you click through to the LA Times opinion piece I wrote about the Silver Lake reservoir, you'll see that it's been correction appended. I wrote in the piece that the reservoir was drained of its entire 600,000 gallon supply, not enough to satisfy one day's water need for the city of Los Angeles. The actual supply contained in the reservoir is 600 million gallons. In fact, when I was writing the piece and doing the calculations, I was thinking in millions but somehow wrote thousands. What this means is that the point remains valid: the 600 million-gallon supply contained in the Silver Lake reservoir is not enough to satisfy a single day's water need for the city of LA.  The city consumes an average of about 602 million gallons of water a day.
