The April unemployment numbers came out a few days ago.
http://www.edd.ca.gov/About_EDD/pdf/urate200905.pdf
Statewide unemployment fell slightly to 11% down from 11.2% in March. In April 2008 California unemployment was 6.6%.
Overall most counties saw about the same small drop in their unemployment as the overall state numbers.
Counties with the highest unemployment rates in California during April were:
Imperial 26.9%
Colusa 19.1%
Trinity 19.1%
Sutter 18.5%
Merced 18.3%
However a few counties saw fairly large drops as seasonal hiring in tourism, agriculture, and construction began.
Some of the counties that saw larger drops in unemployment include
Fresno - 15.5% in April down from March's 17%
Merced - 18.3% down from March's 20.4%
Monterey - 11.7% in April down from March's 15.7%
Santa Cruz - 12% in April down from March's 13.6%
Tulare - 15.4% down from March's 17.7%
Since unemployment can vary drastically between cities in the same county, people should look at individual city rates here:
