California Dairies Confront the Drought

A day after inspecting this irrigation pump on his Shafter, Calif., dairy, Brian Vander Poel had another well break down. “Going forward with this drought, we believe it could be very costly to keep the wells running and maintained,” he says.  

While eyeing record-high milk prices, California’s dairies prepare for limited forage and water supplies.

A field of emerald-colored winter wheat flanks the freestall barns of Skyview Dairy, and the adjoining alfalfa crops have new growth. Holstein heifers romp in their outdoor corral and, in the well-maintained milking parlor, cows stand calmly as employees prep their udders.

On the surface, everything looks picture-perfect at Brian and Kerri Vander Poel’s 1,550-cow dairy near Shafter, Calif. But the early February scene hides a troubling fact: It’s been more than a month since any notable rain fell here in the southern San Joaquin Valley. As the Vander Poels are acutely aware, California’s rainy season is winding down without having delivered anywhere near the state’s needed amounts of rain and snow.

Like thousands of farmers between San Diego and San Francisco, the Vander Poels are facing not only a third year of drought but California’s driest year on record. Snowpacks are scant and major reservoirs are low. In every field, farm office and coffee shop, talk centers on whether there will be enough water to get crops through the summer months. Are pumps powerful enough to pull up groundwater from ever-deeper levels? Could wells run dry? How high will utility bills soar as their pumps work to keep fields and orchards irrigated? And will there be enough forage supplies to feed the state’s 1.78 million dairy cows?

Already, California Governor Jerry Brown has declared an emergency drought. State officials have announced there will be no deliveries of surface water this year. Federal water allocations, to be announced late this month, are expected to be at zero as well. Normally, those two sources account for about 70% of California’s agricultural water needs.

Despite the possibility that thousands of acres of California farmland – for crops like cotton, cantaloupes, broccoli and garlic – may be fallowed this year, empty fields are not an option for dairies and their hungry herds. That means producers in the nation’s No. 1 dairy state are making contingency plans even as they hope Mother Nature delivers desperately needed late-winter storms.

Dairies' major concern is ensuring they have adequate forage supplies. Alfalfa hay is likely to be in short supply as the drought reduces plantings and results in fewer cuttings, says Joel Karlin, commodity manager and market analyst with Western Milling Co. "What’s available will be bid on quite aggressively," Karlin says. "Remember, there’s big demand for hay in the export market."

Prices for top-quality alfalfa hay, now in the $280-$300 per ton range, could rise to $400 if the drought persists, Karlin forecasts. Those high costs could limit alfalfa hay in dairy rations.

Some dairy producers may forego planting corn for silage, choosing instead to produce sorghum, which requires only two waterings compared to corn’s four or five. The downside, however, is that sorghum’s lower quality could lead to reduced milk production.

Farther north at his dairy near Modesto, Calif., producer John Fiscalini is making plans to keep his 1,500 milking cows fed. He may plant 90-day corn instead of his usual 120-day crop, so he can cut back on two waterings this summer. Fiscalini may also abandon the Sudan grass he typically plants as a third crop so he can save two or three irrigations. His dairy typically grows 75% of its silage and buys all of its hay, "which will be more expensive this year," Fiscalini says. He also expects the price of almond hulls, a common feed source for many San Joaquin Valley dairies, to rise since water shortages may force some almond orchards out of production this year.
