CALIFORNIA—The U.S. Drought Monitor has released a report indicated that nearly one-third of the state of California is no longer in what is considered drought conditions. That is the largest drought-free the state of California has seen since 2013.

The U.S. Drought Monitor indicated that just below 30 percent of California is no longer in a drought. About 15 percent of the entire state is drought-free, another 15 percent of California hovers in the preliminary stage of a drought known as “abnormally dry.”

According to weather experts, there is still a lot to be done to improve the drought conditions in the state. California had a below average rainfall in 2015, resulting in San Francisco water officials are having to play catch-up in order to fill the six Hetch Hetchy system reservoirs.

The Hetch Hetchy Reservoir is the primary source of drinking water for San Francisco, as well as other parts of California. Currently, the Hetch Hetchy Reservoir is at 88.7 percent capacity, a 17.7 percent growth from last year’s 71 percent.

“We did not fill our reservoir last year. We need a good couple of years to get us out of that hole,” said Charles Sheehan, spokesperson for the San Francisco Public Utilities Commissions.

One-fifth of California still remains in what is considered an exceptional drought, specifically the southern California region and the Central Coast.
