How much imported water comes from the State vs. the Colorado River?
Figuring it all out is hard because the 'numbers bounce all over the place.'
Determining what percentage of Southern California’s water comes from any single source is complicated. Situations vary considerably every year, according to Karl Seckel, the former chief engineer for the Municipal Water District of Orange County (MWDOC), the county’s water wholesaler.
Seckel now sits on MWDOC’s board of directors.
“You can see that the numbers bounce all over the place,” he said in a Feb. 2022 email full of statistics he had gathered at the request of SC Water Wars. “The accounting of water use is not consistent from source to source and there are many nuances.”
