California continues to battle a sequence of great storms, bringing a lot wanted rain to your complete state, however not fixing the continued water disaster. The storms, which have been described as “atmospheric rivers,” are one other indication of the impression of local weather change and the pressing must adapt the California water system to deal with giant volumes of water in very quick intervals of time, say representatives of Resolve the Water Disaster, which is led by water company leaders throughout California. Local weather change has additionally induced snow packs to soften earlier within the Winter season, making much less water out there for allocations in Spring and Summer time months.

Whereas improved infrastructure can’t forestall all flooding, California’s water provide system should be redesigned to extra successfully shield life and property. Current fireplace and flood occasions exhibit the necessity for generational infrastructure investments so California can handle these excessive water occasions, together with capturing flood flows and shifting them to storage, to be used throughout future dry years.
With trillion gallons of water anticipated to fall on California on account of these latest storm occasions, it’s extra vital than ever to evaluate how we’re capturing and storing this important quantity of rain to make use of sooner or later.
“Historical past has confirmed again and again that we will’t depend on a moist begin to a yr to tug us out of many years of drought. The numerous challenges we face on account of altering and worsening local weather situations not solely require all water managers to work collectively, but additionally requires daring motion by California’s policymakers to alter state water coverage and tackle infrastructure constraints and limitations,” mentioned Heather Dyer, Common Supervisor of San Bernardino Valley Municipal Water District and a pacesetter of Resolve the Water Disaster. “The failure of the system to correctly handle water provide in moist and dry intervals requires a complete long-term answer.”
