Good point.

Fish sometimes occur in a particular place because of things that are
happening nearby. More fish may occur in an open reach without trees, than
one upstream with good canopy, but they may be there feeding on the insects,
detritus, etc. drifting downstream from that same clump of trees. Their
occurrence in the cleared area may have more to do with better visibility,
preferred water velocities, or, preferred water temperatures.
