In response to Gov. Jerry Brown's announcement yesterday, calling all California residents to reduce water use by 25%, the folks at the New York Times put togther a nice interactive map. The map shows residential water use in California in gallons per day.
Take a look here!
/span>The hills and lawns might look green still, but the drought has hit the east bay hard. The sparkling, clean, tasty water we usually have delivered through our taps via the Mokelumne River Basin in the Sierra Nevada. Get out Britas!
From our favorite and fastest source for local news Berkeleyside:
The drinking water for 1 million customers of East Bay Municipal Utilities District had an “off” odor and taste over the weekend and, while EBMUD is fixing the issue, customers might have to get used to it. The culprit? The drought.
EBMUD usually draws the drinking water for the majority of its customers from the bottom of Pardee Reservoir, about 100 miles east of Berkeley, according to Abby Figueroa, a spokeswoman for EBMUD. But on Thursday, the water district started taking water from the top portion of the reservoir. The water there is warmer and contains some algae, so even though it was treated before gushing into pipes in Berkeley, Oakland and elsewhere, there was a peculiar smell.
Accordingly there was a run on Brita filters at all local hardware/houseware stores.

In the paper we document changes in forest structure between historical (1930s) and contemporary (2000s) surveys of California vegetation. The shorthand is:
- Statewide, tree density in forested regions increased by 30% between the two time periods, and forest biomass declined by 19%.
- Larger trees (>60 cm diameter at breast height) declined, whereas smaller trees (<30 cm) have increased.
- Large tree declines were more severe in areas experiencing greater increases in climatic water deficit since the 1930s.
- Forest composition in California in the last century has also shifted toward increased dominance by oaks relative to pines, a pattern consistent with warming and increased water stress, and also with paleohistoric shifts in vegetation in California over the last 150,000 years.

As great as this bath has been, we still are way behind normal.
/span>As a follow-up to this disasterous news about California's water situation, here is a very thought provoking blog about California's water future. They list their 10 predictions for our changed future, including:
- Parts of the Sacramento-San Joaquin Delta will permanently flood.
- The Tulare Basin and San Joaquin River regions will have less irrigated agriculture.
-
Urban areas will use less water per capita, reuse more wastewater and capture more stormwater.
