JayT, here's a source. http://www.cnrfc.noaa.gov/monthly_precip.php
Some areas are way below average (south central valley foothills), others would be above average if one more storm had hit (Shasta Trinity area). Much of the rain did fall in areas without reservoir storage (the lower elevations of the central valley did OK) so Oldgoat is right about the uncatchable portion. It does make you wonder when driving over the flooded Davis causeway on I80 why there are any releases from Shasta and Oroville though.
Oldgoat's comment "if we can't figure out a way to avoid killing off all of the non human animal species, instead of just most of them, then our species doesn't deserve to live" has already been answered. The anthropogenic extinctions (caused by humans during the geologically short time of human existance) already rival the great historical mass extinctions. Perhaps maintaining a strong vibrant ecosystem is more important than preserving traces of the pre human times. Delta smelt? A species decimated by the irrevocably introduced bass and gambusia mosquito fish restricts Delta water transfers that keeps a lot of the central valley and socal going. I certainly don't feel like "deserving" to die for the Delta smelt. Or even be reduced to an unwashed and almond free Iowa grown gruel existence.
San Diego has been on water conservation incentives for a long time. We do have the most expensive water in the world (according to a National Geographic article a few years ago). I don't know if I can cut back on watering the yard we quit watering a few years ago. Replacing the couple rarely used toilets at the office (the well used toilets are already water savers) might save a couple gallons - as long as they weren't manufactured in California.
I don't know any immediate answers to the drought. Farmers along I5 put up billboards to complain in their dry fields. The California salmon run is tiny. And when we dine out at Chez Trop d'Argent we have to ask for water. (I do hope the waiter washed his hands). Such suffering.
San Diego's desalination plant will come online in time for the flood that ends the drought.
Winter's over, I'm going waterskiing.
