Fire hydrants in Los Angeles ran dry in parts of the city when firefighters needed them most, and some of the problems came from pumping water.

The problems with the water pressure running dry in the hydrants, along with the unavailability of the Santa Ynez Reservoir for water supply, led Gov. Gavin Newsom (D-CA) to call for the Los Angeles Department of Water and Power and Los Angeles County to conduct independent investigations on the failings and how to fix them for future fires.
