Go to the NYS Archives in Albany and you will find anything you want: maps,plans of locks, later construction photos, etc. Also check Noble Whitfield's history of the canal system.

Subject: [NYHIST-L] Original Erie Canal Lock Size

I've found  a large number of references online which state that the
original size of the Erie Canal locks was 90 feet by 15 feet, built to
accommodate boats of 61 feet by 7 feet.  I can't find a primary source to
confirm this. Is it true that boats on the original (pre-enlargement) canal
were limited to 61 by 7 feet, and if so, why, if the locks were 90 by 15
feet? Thanks.
