President Trump is heading to Los Angeles this Friday, just as much-needed rain is forecast to hit the area. The visit comes amid a heated debate over California’s wildfires, with Trump repeatedly pointing fingers at Governor Gavin Newsom and other state leaders. He claims they’ve failed to send enough water to Southern California to fight the fires, blaming their focus on protecting the delta smelt, a small endangered fish.

But water experts say Trump’s explanation misses the mark. Southern California’s reservoirs were actually full at the start of the year, and the fires’ spread had more to do with extreme weather and infrastructure issues than water shortages. Trump has even threatened to withhold federal relief funds unless more water is sent south, a move that could spark further conflict in a state already grappling with complex water politics.

California’s water system is a tangled web of competing interests. Most of the state’s water comes from the north, but the majority of its population lives in the south. Add in the needs of farmers, ecosystems, and endangered species like the delta smelt, and it’s easy to see why water management is such a hot-button issue. Trump’s recent executive order, titled “Putting People Over Fish,” aims to redirect more water southward, but critics argue it oversimplifies the problem.

Meanwhile, the fires that ravaged Los Angeles earlier this month exposed flaws in local water systems. In Pacific Palisades, firefighters ran out of water as they battled the flames, but experts say this wasn’t due to a lack of supply. Instead, the infrastructure simply wasn’t designed to handle such a massive blaze. Strong winds also grounded firefighting aircraft, making it harder to contain the flames.

As Trump prepares to visit, the debate over California’s water and wildfire policies shows no signs of cooling down. With rain on the way, some relief may be in sight—but the underlying issues will likely remain long after the skies clear.
