The Sac Bee has this story on a report prepared by Tera Tech says that water shortages by mid-century, California is one of 14 states that face extreme or high risk water shortages.
Virtually all of California faces the prospect of serious water shortages by mid-century due to climate change, the National Resources Defense Council declared today in a national report on water supply.

Dan Lashof, director of the NRDC climate center, said, "This analysis shows climate change will take a serious toll on water supplies throughout the country in the coming decades, with over one out of three U.S. counties facing greater risks of water shortages. Water shortages can strangle economic development and agricultural production and affected communities. As a result, cities and states will bear real and significant costs if Congress fails to take the steps necessary to slow down and reverse the warming trend."
Here is the California temperature trend the National Resources Defense Council is worried about.
The following figure shows the average annual temperature anomalies for the average of the four 5x5 degree grids covering California for 1930 – 2009 (indicated in yellow on the map).This 5x5 degree gridded data is from the Hadley/Climatic Research Unit (CRU) CRUTEM3 database (IPCC uses CRU data), plotted at: [http://www.appinsys.com/GlobalWarming/climate.aspx]
The warmest year was 1934 and there has been no statistically significant warming over the last 80 years. Source details here.
According to the NRDC Study Nevada County does not have anything to worry about. We will not have any drought, global warming or not.
