What's my best bet for water sources. The primary water source would be the los angeles river, which is now an aquaduct through most of la. It terminates in san pedro bay,also know as the port of los angeles. Any delta has long been dredged to improve the harbor. That's probably not going to work. There's a spring nearby in palos verdes, I need to find that again. There is a seasonal spring that runs through the canyon out back, thats were I found some pottery. How about the streams that form after a rainstorm. I tried one yesterday, found a sharks tooth. That's the surface water around here, where would you start first?
