Gov. Gavin Newsom called for an independent investigation into the loss of water pressure to local fire hydrants and the reported unavailability of water supplies from the Santa Ynez Reservoir.

The Lidia fire, which has burned around 395 acres, has been fully contained as of Saturday morning, according to CAL Fire.
