I have to agree with most of the comments so far, lower, and to the left would have been a better composition and POV (I assume to the right would put you in the stream)
The hardest piece is always determining what drew you to the scene in the first place. here's what I see:
1. Dynamic water vs. static objects
2. Objects under water, objects sticking out of water, objects along the water
3. Almost perpendicular intersections of the static and the dynamic.
It's the intersection of the two the catches my eye, so I DL'd your image and cropped to emphasize that that. I also chose a BW conversion because the colors are fairly drab, and don't add to the picture. BW allows one to see the stronger elements underneath the water.
