On a normal day in a normal year, a glass of water poured from any tap in the Santa Clarita Valley contains equal portions of water pumped from local wells and water imported from melting snowpacks in the Sierra Nevadas.
Water availability and water scarcity over the last few years, however, spanning a five-year statewide drought, has thrown the ratio of local water to imported water out of whack.
On Thursday, members of Financial and Operations Committee of the Castaic Lake Water Agency will be presented water production charts that show the CLWA is slowly getting back to the normal years of half-and-half water – half imported, half pumped locally – but not this year.
A breakdown of water pumped from all the local wells this year shows an increasing reliance on imported water since January.
July’s figures of imported-to-local water mark the most pronounced imbalance in more than four years.
For example, the same glass of water poured from any tap in the SCV contained less than 10 percent of the water pumped locally compared to 91.1 percent of it being imported from Northern California.
Drinking that summer glass of water means you would have been drinking almost 100 percent melted snow brought down the Feather River, stored in Orville Dam and conveyed south by the California aqueduct to Castaic Lake as part of the State Water Project.
By contrast, looking at the amount of water pumped out of the ground locally mid-summer in 2013, three quarters of the water consumed in the SCV was imported.
The same was true at mid-summer last year when three quarters of our water originated from Northern California.
