I went running one warm winter afternoon not long ago. It was getting late afternoon and for some reason the river was way down. I have seen it lower. One time I walked almost clear across it. The bottom is hard rock with deep crevices. There is a lot of old construction and oilfield debris. There is also a lot of fish in the remaining pools. I have seen them while crossing the bridges. Here is a video made of the river back in 2014 when the river was low and running clear. It shows among other types of fish a shovel nosed sturgeon which was unexpected.
I am really taken with the idea of all that life taken place hidden in a river running through a big city.
So, how are things where you live?
