California suffered one of its driest years in 2015. And last year the state hit its driest four-year period on record.

But Donald Trump isn't sold. The presumptive GOP nominee told supporters in Fresno, Calif., on Friday night that no such dry spell exists.

Trump said state officials were simply denying water to Central Valley farmers to prioritize the Delta smelt, a native California fish nearing extinction — or as Trump called it, "a certain kind of three-inch fish.”

“We’re going to solve your water problem. You have a water problem that is so insane. It is so ridiculous where they’re taking the water and shoving it out to sea,” Trump told thousands of supporters at the campaign event.

Yes, there is a drought

A series of graphics from the Los Angeles Times shows the progression of the drought from 2011 through today, using data from the U.S. Drought Monitor, a federal website that tracks the dry conditions. The drought worsened in 2014 and 2015 and has marginally subsided this year.

The most recent Drought Monitor report says that over the past week parts of northeastern California and northern Nevada recorded improvements, and "overall conditions have continued to steadily improve during the past year."

Dry spell sparks tensions

Trump spoke in Fresno and San Diego ahead of California's June 7 primary. California is the country's top agriculture producer, and the drought raised tensions among farmers, government officials and environmentalists.

State officials imposed a water ban on June 1, 2015, after record low rain and snowfall. The scarcity was evident from the Sierra Nevada's shrunken snowpack to the dry wells of the Central Valley.

Trump's comments come weeks after Gov. Jerry Brown issued an executive order updating water restrictions. The water rules were imposed in hopes of building the state's "resilience" in the long-term water conservation measures through monthly water use reporting and bans on "clearly wasteful practices such as hosing off sidewalks, driveways and other hardscapes," according to a news release from the California Government Operations Agency's website.

Meanwhile, the powerful farm lobby is trying to secure federal and state approval for billions of dollars to create new water tunnels, dams and other projects.

At least we know where Trump stands on the issue: “If I win, believe me, we’re going to start opening up the water so that you can have your farmers survive."
