Still a good capture! like the lines and colours.

NICE SHOT!

As a quick grab shot it has some potentially interesting elements but it seems visually quite confusing compositionally. Of course this happens all the time but this one is very difficult to concentrate on the picture as a whole. All the major lines run horizontally while the principal subject becomes secondary and moving away almost vertically, leaving another horizontal wake. I simply found it very difficult to concentrate on any single part of a very complex group of divergent images.
At the same time, I wouldn't have passed up the opportunity to shoot it. One thing I think I would have done is to shoot from a lower perspective and crop of the far shoreline but leaving in the reflections in the water. Also crop some from the right to de-centralize the principal subject.

Yeah, I'm with snapshooter above... shoot first and ask questions later. Love the golden reflections on the far side of the dam, repeated by the golden grasses in the foreground. Yes, this would do well with cropping, particularly with the strong horizontal line of the dam itself... but there is no good place to crop it and still keep your background and foreground color. I'd say, go back and set up on a tripod...get your composition the way you want it...and pay some guy with a dog to chase a goose into your viewer!

Surprisingly, despite the fact that it looks a tad cold and the duck is all on his own, I don't find this a lonely image at all, I think it is quite lovely and peaceful actually:)
