:::KChase02:  Good work on the table!  I've revised it slightly to include both downstream and upstream elevations.  AFAIK, the level of the canal changes only once other than by lock, between locks 33 and 34, not 34 and 35.  Most of the information about the elevation and lift is coming from two sources  the information signs on the locks themselves (see http://www.galenfrysinger.com/erie_canal_locks.htm).  Note that, for example, the sign for 34/35 at Lockport shows the downstream elevation as 514.9 but the sign for lock 33 shows the upstream elevation as 512.9.  As such, I believe the elevation change to occur there. 

 :::Beyond these sign photos, my other source is a .pdf file at http://www.eriecanal.org/images/misc/canal_profile.jpg.  Here you will notice that if you start with the Troy-US lock on the eastern side of the canal (which takes the Hudson River at 1.4 feet and raises it 14' to 15.3 feet, the start of the Erie Canal, and add all of the lift elevations the math works out perfectly (thus I do not see a difference between any other locks).  If you can confirm that the table data is wrong, though, please identify the source and modify it.  Otherwise, I think the table you created is ready for publication. 

 :::As for the mileage that is unknown, I think we should just list it as "n/a" for now.  If someone knows it, they can modify the table later. 

 :::Lastly, as for the individual lock pages, I suggest deleting them all. The ones that existed before have interesting picutres, but add little informational value.
