Unlike many #rivers that terminate in a #seaport, the #LARiver was never navigable by ship. It was more of a marshy estuarial system, fanning out all over #wetlands. The placement of the #LosAngeles/ #LongBeach #ports is actually kind of arbitrary as far as the river is concerned--but the river had to be managed to support #railroads & later, freeways.

Here you can see downtown LA thru haze (& electrical pylons). DTLA is ~20 miles north of where the river terminates in San Pedro Bay
