I would agree.  The water level is easy to adjust, though, as it's a separate prop which can be lowered.  There should be some muddy creek bank showing, but the water is up to the grass.  I didn't see that blue cast in earlier shots.  I'd agree that creek water is at best colorless, and usually green/brown.  That's easily adjusted, too.
