In my experience, and I'm not involved in industry end-resource crossings and that sort of thing, probably the biggest issues I see are minor crossings on minor streams, things that would probably more often fall to the municipalities, even, than to us; cases in which they believe that a stream is not used for navigation and that a small culvert crossing or low-level crossing is adequate to meet their traffic needs and is economical and, since nobody paddles here anyway, wonder who the heck cares whether a canoe could theoretically get under it. That's where I see most of the conflicts right now.
