4-Year California Rainfall Deficit
2011-12 to 2014-15
 by Jan Null, CCM
 Updated June 23,  2015
These tables and chart show the total deficit in California rainfall since the 2011-2012 season July 1 to June 30) in both inches and percent of normal.

For example, San Francisco is 31.63 inches behind their normal four-year total.  Consequently, to make up all of the deficit, the rainfall that San Francisco would need this coming winter would be 55.28" (i.e., 31.63" + 23.65") or 234% of normal. [The all time record for San Francisco is 49.27"!!]

It should be noted that making up the rainfall deficit is very different than the requirements to "end the drought" as the components of a drought are dependant upon a myriad of variables like the type of user, population, existing supplies etc.
