LinkedInEl Niño isn't filling Monterey County lakes as quickly as other state reservoirs
In December, Lake Nacimiento was at 16 to 17 percent of capacity. It has now risen to 22 percent. Lake San Antonio, which dropped to 3 percent of capacity last summer, is still at 3 percent now. It is so low that engineers refer to it as a "dead pool" because gravity cannot pull water out of the reservoir when it is at that level.
The Monterey County lakes don't fill as quickly as other lakes - such as Shasta, Folsom and Oroville - because they are fed by relatively small watersheds. Nacimiento and San Antonio were built in the 1950s and '60s for flood control and to recharge aquifers. With dropping aquifer water levels, farmers have had problems with their wells, the story said.
“Some growers' wells pull in as much air as water, so that they need repairs or lose the wells entirely. I've seen well drillers around, which indicates re-drilling,” said Michael Cahn, a UC Agriculture and Natural Resources Cooperative Extension advisor in Monterey County. “This is a cost for agriculture.”
As they drill deeper, farmers also risk more seawater flooding in, contaminating the limited water supply. It was seawater intrusion that originally led to the construction of the Nacimiento and San Antonio dams.
Cahn was quoted at the end of the story with a positive message.
“The aquifers are currently at the lowest levels ever recorded, but they can go back up,” he said.
