President Trump startled some of his most ardent supporters in the San Joaquin Valley by having the Army Corps of Engineers suddenly release water from two dams.

The Army Corps of Engineers' decision to release water from dams in the San Joaquin Valley is causing concern among regional water managers.

It comes after water shortages allegedly hampered firefighting efforts in Los Angeles—a claim that state officials deny.

There are two major problems with Trump’s order, water experts said: The water will not flow to Los Angeles, and it is being wasted by being released during the wet winter season.

After the tragic wildfires in Southern California, President Trump often attributed the disaster to what he said was a lack of water being sent from the northern part of the state, and vowed to fix the problem.
