‘Miracle year’: California records above average rain and snowfall

After years of drought, California will end its water year with above-average rain and snow. Experts say this could have played a role in the state’s smaller wildfire season. With this year’s El Niño and predicted storms, there are concerns over flooding.

At Lake Oroville in Butte County, California, water rushes out of the spillway on March 26, 2023. The reservoirs in the state water project ended the water year on Sept. 30, 2023, at 128% of their historical average, which includes Lake Oroville.

California ended its “miracle” water year on Saturday with enough rain and snow to fill the state’s reservoirs to 128% of their historical average, making it among the wettest years in recorded state history.

That’s a welcome boon to a state that has spent much of the past dozen years in a deep drought, forcing state leaders to grapple with how the state should share and manage its water in the future. A series of winter storms in early 2023 busted the state’s most recent dry spell.

State officials measured 33.56 inches of precipitation through the end of September. California’s “water year” begins annually on Oct. 1 so it can include all of the fall and winter months when California gets the bulk of its rain and snow. The state depends on those wet months to fill its reservoirs that supply water for drinking, farming, and environmental uses throughout the state.

Those reservoirs dipped to dangerously low levels in recent years because of an extreme drought. That prompted water restrictions on homes and businesses and curtailed deliveries to farmers. It also threatened already endangered species of fish, including salmon, that need cold water in the rivers to survive.

Statewide, reservoirs held 27.4 million acre-feet of stored water as September ended. One acre-foot of water is enough to supply two families of four for a year. About 4.5 million acre-feet are held in the State Water Project, a network of 30 reservoirs and storage facilities that provide water to 27 million people.

“This was as close to a miracle year as you can get,” said Karla Nemeth, director of the California Department of Water Resources.

The reservoirs were helped by a series of nine strong storms that hit California over the winter. Those storms carried so much rain and snow they were known as “atmospheric rivers.” They caused widespread flooding throughout the state and were blamed for multiple deaths.

The storms also dumped tons of snow on the mountains. The state snowpack on April 1 was 237% above its historical average. It’s just the fourth time since 1950 that the state’s snowpack exceeded 200% of the average, according to Michael Anderson, the state’s climatologist.

All of that snow melted in the spring and summer, filling rushing rivers and reservoirs. Water levels at Lake Oroville rose 240 feet between Dec. 1, 2022, and the end of the snowmelt period. That’s the largest increase in storage in one season since the reservoir opened in 1968, according to Ted Craddock, deputy director for the State Water Project.

State and federal officials will have to drain some of the reservoirs to make room for more water that’s expected to come this year. The state’s rainy season could be complicated by El Niño  – the natural, temporary, and occasional warming of part of the Pacific Ocean. El Niño affects weather patterns around the world. California typically gets more rain and snow during El Niño year. This year’s El Niño has a 56% chance to be considered strong and a 25% chance to reach supersized levels, according to the National Oceanic and Atmospheric Administration.

The potential for more strong storms this year, particularly along the coast, “keeps me awake a little bit at night,” said Gary Lippner, deputy director for flood management and dam safety with the California Department of Water Resources.

“We just do not have extensive flood systems on the coast of California,” he said. “That’s an area we’re paying particular attention to.”

All of the rain and snow this year could have played a part in what has so far been a smaller wildfire season. Wildfires exploded in size during the drought in part because of the super dry conditions. So far this year, just over 476 square miles have burned in California. That’s well below the five-year average of 2,031 square miles, according to the California Department of Forestry and Fire Protection.

What is the Monitor difference? Tackling the tough headlines – with humanity. Listening to sources – with respect. Seeing the story that others are missing by reporting what so often gets overlooked: the values that connect us. That’s Monitor reporting – news that changes how you see the world.

Dear Reader,

About a year ago, I happened upon this statement about the Monitor in the Harvard Business Review – under the charming heading of “do things that don’t interest you”:

“Many things that end up” being meaningful, writes social scientist Joseph Grenny, “have come from conference workshops, articles, or online videos that began as a chore and ended with an insight. My work in Kenya, for example, was heavily influenced by a Christian Science Monitor article I had forced myself to read 10 years earlier. Sometimes, we call things ‘boring’ simply because they lie outside the box we are currently in.”

If you were to come up with a punchline to a joke about the Monitor, that would probably be it. We’re seen as being global, fair, insightful, and perhaps a bit too earnest. We’re the bran muffin of journalism.

But you know what? We change lives. And I’m going to argue that we change lives precisely because we force open that too-small box that most human beings think they live in.

The Monitor is a peculiar little publication that’s hard for the world to figure out. We’re run by a church, but we’re not only for church members and we’re not about converting people. We’re known as being fair even as the world becomes as polarized as at any time since the newspaper’s founding in 1908.

We have a mission beyond circulation, we want to bridge divides. We’re about kicking down the door of thought everywhere and saying, “You are bigger and more capable than you realize. And we can prove it.”

If you’re looking for bran muffin journalism, you can subscribe to the Monitor for $15. You’ll get the Monitor Weekly magazine, the Monitor Daily email, and unlimited access to CSMonitor.com.
