Why Water Conservation Officials are Intentionally Flooding Central Valley Vineyards
ACAMPO -- Flooding in a San Joaquin County vineyard is an odd sight before the beginning of the rainy season. But the flooding in Al Costa’s stand of Zinfandel vines is entirely man-caused, with water being pumped from the adjacent Mokelumne River at the rate of 4,000 gallons per minute. It's part of a pilot project using East Bay Municipal Utility District allotted water to replenish the groundwater in the region. The North San Joaquin Water Conservation District is working with EBMUD and the Sustainable Conservation to see how crops can withstand a soaking and to see how much of the water actually filters into the water table.
