On 30 April 2014, The California Department of Water Resources released a report analyzing 5,400 groundwater wells across the state — signaling historic declines in water levels. Groundwater provides approximately 60% of California’s water supply in a dry year (40% in an average year) and 2013 was the driest in recorded history. In many areas of the San Joaquin Valley, recent groundwater levels are more than 100 feet below previous historical lows.
