Lady Gaga is is set to make a public service announcement encouraging Californians to save water during the drought.

But first she has to fill up this leaky swimming pool.

Gaga, according to the Los Angeles Times, wants to host a special event at the famous Neptune swimming pool at the San Simeon Hearst Castle. But the pool, which leaks 5,000 gallons a day, has been empty since January.

So Gaga will pay for water to be pumped from a storage facility into the pool and then back into the storage facility.

The singer, whose real name is Stefani Germanotta, will also donate $250,000 to the Hearst Castle Foundation and pay the standard $22,000 fee for filming at the castle. She is also paying $25,000 for a water supply study in Cambria, according to the Times.

Gov. Jerry Brown wrote Gaga a thank-you note, the Times reported.

“I want to personally thank you for the aid and assistance you are providing to Hearst Castle, the communities surrounding San Simeon and the state as a whole,” Brown wrote. “I’ve called on all Californians to conserve water in every way possible and the assistance you are providing will aid in that effort.”
