Summer marks the traditional beginning of California’s fire season, although the warming climate has stretched the season considerably. Until the winter rains arrive, wildfires will burn forests and grasslands throughout the state. Since January 1, about 3,700 fires have consumed more than 111,000 acres of land—outpacing 2017, the most destructive and deadly fire season in state history. While public safety and economic costs deserve and receive a great deal of attention, wildfires also have consequences for the management of water—including the amount and quality of supply, and the potential for flooding.
