Crops feeling the heat from the California drought include, hay, wheat, olives and corn. Livestock deaths have increased because of the lack of water in the state.
Rice production also has been hit, with nearly 25 percent of the state's $5 billion rice crop likely to be lost this year due to lack of water, experts said.

Dairy production is also down. California, which is the top milk producer in the U.S., has lost 1 percent to 2 percent of its dairy industry because of the drought in the last three years, according to recent statistics.
The falloff in crop and livestock production from the drought—along with increased costs for groundwater use—is expected to cost California $1.5 billion this year, according to a report from the University of California, Davis. Some 17,000 seasonal and part-time jobs will also be lost.
An estimated 420,000 acres of farmland went unplanted this year—about 5 percent of the total in the state. The entire statewide economic cost of the 2014 drought is paced at $2.2 billion.
Even the state's pumpkin growers are facing problems from the lack of rain. Next to Illinois, California is the second-largest pumpkin producer in the country.
"The impact is very severe on us, and if we don't get rain this winter we won't be able to grow anything," said Wayne Martin, a farmer in Fresno, California, who grows pumpkins on his 60 acres of land.
"It's very bad here with the little water we have," he said.
Residents, too, are feeling the pain. Some 500 people in Tulare County, in the central part of the state, cannot flush a toilet, wash clothes or drink water out of the tap because water sources have dried up.
