It is an excellent picture in clarity however the artistic merit is not as high as it could be - the lighting is just flat bright sunlight. A shot of this bridge in early morning light or twilight would produce a much better image.
If they go any deeper they may not be wading anymore. Looks like fun. Good angle, however I agree with trixxi17. You need to get a shot of the bridge itself in the early morning or late evening.
This is Nebraska (i.e. flat country). The Niobrara is normally about 2 feet deep. It was high at 3 feet when we went down. The only hard part about crossing was the current. :-)
Thanks for the suggestion about timing -- though at early morning or twilight I might have had a hard time convincing the kids to brave the mesquitos. :-)
