A small water district in Mendocino County will be shutting off the valves Monday that supply irrigation to more than 2,000 acres of vineyards and other crops, leaving nearly 200 farming customers without their main source of water, a shortfall that likely foreshadows what's ahead statewide for many growers as the drought stretches on.
There just isn't enough water in Lake Mendocino, the main reservoir in the upper Russian River basin, to supply all water users, officials said.
For the Redwood Valley County Water District, that means prioritizing deliveries to its 5,000 residential customers over its farmers, as required by state law.
"We had no choice. It's the last thing we wanted to do," said Ken Todd, a Redwood Valley water board member who owns 150acres of vineyards and manages another 150 acres for others in the valley, located about 8miles north of Ukiah.
Under the best of circumstances, Todd said he expects to lose 20 percent of the winegrape crops on about half the vineyards he oversees — the ones with only small reservoirs to make it through the growing season. At worst, it could be a total loss this year for those vineyards, he said.
The 50-year-old Redwood Valley water district is in a pinch because it has a limited right to water from Lake Mendocino. In dry years, that right is practically non-existent. The district has operated under a decades-long moratorium for new hookups because of the situation.
On Thursday night, however, district officials said they made an unprecedented springtime decision, voting 3 to 1, with one abstention, to cut off water supplies to all of their growers.
The move looks to be the first instance of a water supplier halting deliveries on the North Coast amid the current drought.
It comes after California last year recorded its driest year on record, and as farmers in the Central Valley, the state's main agricultural region, and agencies serving more than 25 million residents are facing drastically lower deliveries, with just 5 percent of their requested allotment expected from the State Water Project this season.
On the North Coast, which has different water supply, growers are expecting curtailments as well.
"This is going to be a very difficult year for everybody," said Devon Jones, executive director of the Mendocino County Farm Bureau.
The Redwood Valley water district has long struggled with securing an adequate water supply for its customers. Its officials have pushed various ways to address the shortfall, including raising the height of Coyote Dam at Lake Mendocino to store more water and creating a new diversion from the Eel River to boost supplies.
The state's current three-year drought has revived the problem in a new, more urgent way, leading to the earliest seasonal curtailment that district officials and others in the area can recall.
"I don't believe they've ever cut agriculture off for the main part of the season," said Janet Pauli, a grape and pear grower who sits on several local water agency boards.
The decision follows a failed attempt to get federal regulators to increase water diversions from the Eel River to the Russian River, which feeds Lake Mendocino. The district pumps out of the lake.
Local water agencies and farmers have criticized the denial of additional water, accusing regulators of mismanaging water resources and adding a "regulatory drought" to nature's shortfall.
