>I bet that they could pump a lot more water if instead of directing all of the storm water into those huge concrete waterways, they replaced some unused parking lots and other properties with detention ponds so that the water could get into the ground.
Very little water flowing down the San Gabriel river makes it to the sea; it's almost all captured in dams and retention ponds, or it seeps through the gravel riverbed.
The LA river is another matter; Nobody thought about capturing its flow when the Corps of Engineers channelized it back in the thirties, so on the rare occasions when it floods the waterflow is lost.
