Opinion: Rains and Flooding Are Not Enough to Solve California’s Persistent Drought Problems

California’s reservoirs may be as full as they’ve been in years thanks to recent rainfall, but it’s still not enough water to meet the state’s demands — and it will never be if the state doesn’t invest in new ways to capture all that precious water.

Not enough of the state’s heavy rainfall is draining into California’s underground reservoirs to keep us sated, even through the next summer.

Did Winter Storms Replenish California’s Depleted Groundwater Supplies? Here’s What Data Shows.

Winter storms have filled California’s reservoirs and built up a colossal Sierra snowpack that’s nearly twice its normal size for this time of year. But years of dry conditions have created problems far beneath the Earth’s surface that aren’t as easily addressed.

Groundwater — found in underground layers containing sand, soil and rock — is crucial for drinking water and sustaining farms.

Here’s How Much the Latest Rainstorms Affected Water Levels in California’s Reservoirs

The storms that rolled across the Bay Area and much of California on Sunday and Monday delivered some of the highest rainfall totals of the calendar year so far, as meteorologists predicted — but that still isn’t much, they said Tuesday.

“On a bigger picture, this is one of the biggest storms we’ve had of 2022,” said Matt Mehle, a meteorologist with the National Weather Service. “But we’ve only had a handful of systems actually bring any precipitation to the Bay Area in January and February.”
