How wet is your winter? Water and drought in Sonoma County
Bob Dylan was spot-on when he sang, "You don't need a weatherman to know which way the wind blows." He was also spot-on when he sang, "A hard rain's gonna fall," though hard rains donāt fall as often as they once did in the hills and valleys of Sonoma County where drought has become the new normal. Huge weather eventsā once referred to as āPineapple Expressesā and now usually described as āAtmospheric Riversāāhave been around for a while, but they seem to take place more frequently now than in the past. The data isnāt conclusive. Still, an atmospheric river can occur during a year of intense drought. Not long ago, the Russian River flooded during a season of below average precipitation. Welcome to the wacky world of weather.
Local patterns
Weather patterns thousands of miles away, in the south and the central Pacific Ocean, known as La Nina, which has water on the cool side, and El Nino, with water on the warmer side, also seem to influence patterns of Sonoma rainfall. Still, direct cause-and-effect relationships have not been proven beyond the shadow of a doubt, or so experts believe. What is apparent, folks at the Sonoma County Water agency, aka Sonoma Water, insist is that weather events that take place in distant parts of the globe, impact local weather events. Itās all connected. Sub-Saharan Africa has been harder hit than other places and has give rise to climate change refugees eager to find sanctuary in Europe. Northern Californians have fled smoke and fire, but they had not yet fled drought.
Mr. Dylan, ought to rewrite the lyrics to his classic, āSubterranean Homesick Blues.ā The new version would go, "You don't need a weatherman to know we're in the midst of global warming, climate change and weather extremes." Yes, there are those who deny climate change, but anyone who has lived in Sonoma County over the past four decades, as I have, paid attention and kept records of precipitation and temperatures will tell you that there's less rainfall now than there once was.
Local concerns
Also, summer days are hotter than ever and hot days occur more often now than in the past. That, too, is the new normal. Not surprisingly there are gloom and doom people in our midst. One of them is legendary environmentalist, teacher and founder of Green String Farm, Bob Cannard, who thinks that Sonoma County will look like the Sahara Desert. But that wonāt be, he predicts, for another hundred years.
Green String Farm on the outskirts of Petaluma doesnāt have reliable wells and the water that Cannard stores in reservoirs usually runs out before the end of summer. Heās worried he won't be able to grow organic vegetables much longer at Green String.
Iāve had far better luck with the well on my own property in West County that Bob Foote dug in 1972. Itās 88-feet deep and it still supplies eight-gallons a minute. Like Cannard, Iām a worrier. I had a fit when one neighbor ripped out the apple trees in the orchard next to my parcel. I had another fit when yet another neighbor cut down the redwoods on the acreage right above me that had helped to sustain the watershed. I understand that property comes with rights and privileges, but isnāt there also the responsibility to the earth itself and to the community?
In a county that's still largely agricultural, and where all water is localāthe town of Sonoma differs from Cotati and both differ from Santa Rosaāthe subject of the weather is more than one of innocent curiosity. For longtime vineyard manager, Phil Coturri, who also makes his own wines āunder the Sixteen 600 label with his two sons and right-hand men Max and Samāknowing weather patterns is as essential as knowing how much money he has in the bank.
In fact, heat and rain can be the difference between profit and loss. When it's too hot grapes fry on the vine. No wonder Sonoma County grape growers and winemakers have been thinking of moving vineyards to the Sonoma coast and to Oregon and the State of Washington. Some have already bought land along the Pacific. That move can buy time, but there's no guarantee that the Sonoma Coast and the Pacific Northwest will be suitable for Pinot Noir and Cabernet Sauvignon. The weather conundrum, if you can call it that, is global.
As Lisa Michelli, the President and CEO at Pepperwood Preserve, says, "God is playing dice with rain." She adds, āItās essential to take care of the land because if you do that, you also take care of water.ā Well-cared for land absorbs and stores water under the surface, Michelli explains. āGround water,ā as itās called, is as good as savings. At Pepperwoodās 3,200-acres, which sit in the hills above Santa Rosaāand thatās on the traditional homeland of the WappoāMichelli and the crew monitor and measure temperatures and rainfall. āThereās no substitute for going into the world, looking, seeing and observing, and not relying on computer models,ā Michelli says. She believes in vineyards because theyāre ārecharge areasā where water goes into the ground and doesnāt run-off and flow to the ocean. She also insists, āEveryone has to take responsibility for the well-being of the aquifer.ā
