I guess that depends on what you're trying to do...  If you are trying<br>
to tag the largest possible vessel that can navigate a waterway (under<br>
"normal" conditions at least) you could probably come up with a<br>
reasonable set of tags.  Inland waterways are highly dynamic though...<br>

The Army Corps has well-defined channels that they regularly dredge to a specified depth and width. Can this be matched to some sort of barge classification?<div class="HOEnZb"><div class="h5"><br>
