As record rainfall inundated Southern California last week, the scene at the mouth of the Los Angeles River in Long Beach was dramatic.
The flow of water was ferocious — some 65,000 cubic feet per second at the terminus of the L.A. River’s flood control system . That’s like 65,000 basketballs going by, every second, that are filled with water and weigh 62 pounds apiece, said Los Angeles County public works director Mark Pestrella.
Even more impressive was that for all the rain — nearly 9 inches over three days, the second-wettest three-day period on record for downtown Los Angeles since recordkeeping began in 1877 — the L.A. River was just at one-third of its capacity.
It could have easily handled a much bigger storm.
