Lake Champlain - Richelieu River

This set of 75 maps starts in Whitehall NY on the Champlain Canal and goes along the western shore of Lake Champlain north into Quebec.  It follows the Richelieu River to Sorel-Tracy.  This is a total distance of approximately 218 statute miles.  In Canada, the maps were numbered using nautical miles as that system is used there.  (On the maps, “NM” means nautical miles and “MM” are statute miles.)

River Thames

This is another one that I did myself.  There was no river mile numbering system that I could find on the Internet.  So I made one up starting at the so called “Yantlet Line” near the river mouth to the Thames Source.  The Yantlet line dates back to 1300 or so.  It was the limit of of the City of London’s jurisdiction over the river for centuries.  (See: http://en.wikipedia.org/wiki/London_Stone_%28riparian%29) 

Actually, the Thames Source is somewhat controversial as well.  The true source is actually along another tributary to the north.  No matter.  The river isn’t navigable upstream of Cricklade.  That is where my friends will begin their journey.  BTW, that trip was supposed to happen this fall but has been postponed to March of 2013.  I figured I would post the map now so that perhaps someone else might find the line and points of interest useful.  It’s kind of a work in progress.  More will likely be added to it after the first of the year.

The Thames National Trail is also on the kmz file.  That is a footpath the runs from the Thames Barrier to the Thames Source.  In the lower reaches there are actually two paths, one on each side of the river. 

Savannah River

This is another map based on Corps of Engineers data.  For some reason, it started at Mile Point 11.  So I extended it down to the Atlantic Ocean.  Also, the Corps stopped the numbering at Mile Point 200 although the river extends well beyond that.  If anyone were interested in the upper reach, the numbering could be easily extended.
