It is right there, honest! It was located right behind the tree stump, this photograph would have been of its side and nothing else. It is interesting to note that one of the two channels the river is taking is the old raceway for the cotton factory. The other, of course, is the old main channel.  Despite being out of use for over a century and inundated by flood waters for sixty plus, the old river bed channels remain very real and very active in a reservoir, even in this location which has accumulated feet of silt and mud already. They are by no means flat pools.
