Just to put things in perspective, on January 2nd, 1997 the Merced River peaked at 23.4′ at the Pohono Bridge. That’s 13.4′ above flood stage. According to the CDEC, yesterday’s flood peaked at 11.24′.
I expect that with the thunderheads headed Yosemite way today and a weeks worth of temps in the 90’s, we might just beat that record.
