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.
