California Just Experienced a ‘Miracle’ Water Year. But Winter Could Bring New Challenges

The typically parched, brown hills above Los Angeles are a vibrant shade of green — a rarity for early October.

In state parks, waterfalls and rivers that were vastly reduced are now gushing with water.

And in Lake Oroville, boats float on deep blue water that only a year ago was shrinking toward record lows.

The transformed landscape is the result of a remarkable California water year that saw 141% of average rainfall statewide, officials announced this week. The state received 33.56 inches of rain — nearly twice the amount of rain recorded during the previous water year and nearly three times the amount from the year prior. The water year runs from Oct. 1 to Sept. 30.

“This past winter storms provided a huge boost to the state water projects, water supply, especially at our largest reservoir at Lake Oroville,” said Ted Craddock, Deputy Director of the State Water Project.

CW3E Kicks Off the Water Year 2023 West-WRF Forecast Season

The Center for Western Weather and Water Extremes (CW3E) at Scripps Institution of Oceanography runs a weather prediction system called ‘West-WRF’ that has been optimized for predicting rainfall along the West Coast primarily from atmospheric rivers (AR). Forecast data from West-WRF is used by water managers to improve reservoir operations and to inform CW3E AR reconnaissance activities.
