This is a picture of the dam that tom and John built out of large rocks, logs, and tons of gravel. Note the two large beige rocks in the back of the picture, and the relatively low water level. (photo taken looking downstream)
After a day and a half of serious rain, here’s another photo of that same area (photo taken looking upstream), with yellow arrow at those same beige rocks, so you can orient yourself.
Ahhh, California – it’s a feast or famine weather state, it seems!
