YOSEMITE NATIONAL PARK, Calif. — A wildfire near Yosemite National Park — already one of the biggest in California’s history — continued to grow on Sunday, prompting mandatory evacuation orders for some residents and raising anxiety among officials because of the potential threat to a major source of San Francisco’s water and power supplies.

The so-called Rim Fire had burned about 134,000 acres as of late Sunday — about 9,000 acres more than it had the previous day — making it the 14th largest fire since California began keeping records on wildfires in 1932 and the second largest in Tuolumne County.

Officials said that firefighters had contained about 7 percent of the fire, which began just over a week ago, and that it had caused no loss of life or significant property damage. And although the fire has burned some acreage in Yosemite, the most visited area of the park, the Yosemite Valley, is not threatened so far, officials said.

Despite its size, the fire has not threatened population centers or heavily trafficked parts of Yosemite, but it was more the potential of the fire than the actual damage so far that spurred officials into action. Officials said that the fire tripled in size from Wednesday to Thursday and then doubled again from Thursday to Friday.
