The president also was announcing that the budget he'll send to Congress next month will include $1 billion for a proposed "climate resilience fund" to invest in research and pay for new technologies to help communities deal with the impact of climate change. The proposal is likely to face stiff resistance from lawmakers wary of new spending and divided on the subject of global warming.
Later Friday, Obama was meeting Jordan's King Abdullah II at Sunnylands for talks covering the Mideast peace process, Syria and other issues. It's unusual for Obama to host world leaders outside of the White House, though he did hold a two-day summit at Sunnylands last year with Chinese President Xi Jinping.
Obama's meetings with Abdullah will be much shorter just a brief meeting Friday night, followed by a working dinner. The White House wouldn't say why the meeting was taking place in California, particularly given that Abdullah spent much of the past week in Washington and met with Vice President Joe Biden, Secretary of State John Kerry, House Speaker John Boehner, R-Ohio, and others
"The king is also going out to California. The president and the king can meet there and will meet there as part of this trip," said White House press secretary Jay Carney.
Obama was expected to spend Presidents Day weekend on the golf course at Sunnylands. He's traveling without first lady Michelle Obama.
The White House has been closely watching the California drought, which follows a year of the lowest rainfall on record. The drought has also brought to a head political warfare over the state's water resources that feed major cities, the country's richest agricultural region and waterways that provide habitat for endangered species of fish.
Gov. Jerry Brown declared a drought emergency on Jan. 17. Obama telephoned him several days later for an update on the situation.
Farmers recently learned they will not be receiving irrigation water from the State Water Project, a system of rivers, canals and reservoirs. They anticipate a similar announcement later this month from federal authorities who operate a similar system called the Central Valley Project.
Federal officials, including Agriculture Secretary Tom Vilsack, earlier this month pledged $34 million to help farmers and ranchers conserve scarce water supplies, improve irrigation methods, head off erosion of unplanted fields and create better ways to water livestock.
The Republican-controlled House recently voted to address the drought by rolling back environmental protections and temporarily halting the restoration of a dried-up stretch of the San Joaquin River, work that is designed to restore historic salmon runs. Farmers would prefer to have the water diverted to their crops instead.
Boehner recently showed his support for the bill by visiting a dusty field in Bakersfield and saying fish shouldn't be favored over people.
Environmentalists and Democrats oppose the bill, and the White House has threatened a veto, arguing that the measure would not alleviate the drought but would undo decades of work to address California's longstanding water shortages.
In response, California's senators, Dianne Feinstein and Barbara Boxer, joined fellow Democrats in proposing legislation that would pour $300 million into emergency aid and drought relief projects, upgrade city water systems and water conservation and speed up environmental reviews of water projects, among other steps.
