The emergency that unfolded recently at Oroville Dam in Northern California poses no immediate or projected impact to water supplies in San Diego County. Voice of San Diego’s story on the crisis, though, states that “we could lose a significant chunk of our water supply, perhaps even 20-25 percent.” Low winter water demand, significant water reserves in Southern California and local investments in water supply reliability will allow the San Diego County Water Authority to provide uninterrupted water service here even if deliveries from Oroville are impacted.
