The North Coast needs an additional foot of rain between now and May just to get back to drought conditions seen in 1977, and even then Lake Mendocino could still go bone dry by autumn for the first time in recorded history, water officials said Tuesday.
The warning stunned North Coast grape growers who packed a Cloverdale meeting hall Tuesday to discuss ways of saving their crops amid the worst drought any of them can recall.
None of the strategies, which ranged from installing more wind machines to covering ponds with plastic tarps to reduce evaporation, compared with what everyone agreed is the most pressing need: more rain and lots of it.
If Lake Mendocino runs dry, it could be disaster for growers, in particular those with vineyards along the upper Russian River. Many rely on water from Lake Mendocino for irrigation, as well as for frost protection.
“If you're below Dry Creek, it's going to be a bad year. If you're above Dry Creek, it's going to be a biblical year,” said Sean White, general manager of the Russian River Flood Control District.
Dry Creek is a Russian River tributary that carries outflow from Lake Sonoma, the principal water source for much of Sonoma County. Dry Creek joins the Russian River southwest of Healdsburg.
White's assessment silenced the crowd of more than 150 growers, vineyard managers, scientists and government officials who gathered Tuesday at the Cloverdale Citrus Fairgrounds for the meeting, which was sponsored by the Mendocino County Farm Bureau and Sonoma County Winegrowers.
Grape growers have been on notice for weeks that their livelihoods are at risk this year because of the dry weather, which has accelerated bud activity across the region and heightened fears of frost damage. As a result, many growers have purchased crop insurance.
“I think everybody's got a good sense of the reality,” said Bob Anderson, executive director of United Winegrowers for Sonoma County.
