Thank you for all the valuable information. I wanted to make a forested lake and river terrain. Here is a version with a scale included. I'll have to get used to drawing up a scale early on. If it is useful I have included the Wilbur file from which I am deriving my rivers from.
I do want to have wide rivers, so based on the opinions above that must mean I need longer tributaries, and due to the lack of space available that might mean I need less rivers. Does that sound right then? I expect it would be hard to see the way tributaries actually look within a forest.

Hah, actually looking up the amazon river width I have to change my statement about intended river width. I want the rivers to take up plenty of space on the visual map, but at the same time I want to work with the scale I have included. The Amazon River is like 7 miles wide. I don't want anything like that.
I think I have to refigure my river width or scale.
