After Gov. Arnold Schwarzenegger declared a state of emergency over drought conditions in California, farmers in the Central Valley are feeling many of the effects of the decision.

The San Luis Reservoir, which has been a main source for Central Valley farmers since its completion in the 1960s, will not give off any water this year. The reservoir is filled with federally provided water and is the nation's largest water basin without a natural stream.  

This means that the federal government decides not only how much water goes into the reservoir, but how much is ultimately released.  This year, because of the scarcity of water in California, that number is zero.  

Because Central Valley farmers will not get any federal water from the San Luis Reservoir this year, they will have to rely on other sources, like heavy rainfall and pumping their own water from personal wells. 

But nature doesn't seem to be on the farmers' side, either. According to Fresno City Council President Cynthia Sterling, the average rainfall for Fresno -- a city in the Central Valley -- is about 9 inches per year. The city has received 6 inches so far this rainy season. 

Sterling also said Fresno is in its third year of drought and hasn't received its expected amount of rainfall for years. 

As for generating water themselves, pumping from personal wells is only an option for farmers who own the resource.  Some Valley farmers don't own wells and rely completely on federal water and rain.
