Someone asked about another canal song and had fragments of lyrics. Here's the song (which I also learned in 5th grade, growing up in Akron).

Up the Cuyahoga far as Akron
Over locks aplenty to Coshocton.
Newark, Chillocothe, and down along the Sio.
Then to Portsmouth on the broad Ohio.

Float her high boys, float her low-ow-ow.
Through the locks boys, ease her slow-ow-ow.
Always heading for the valley we'll be seeing by and by.

For we'll keep the locks arunning til we pump Lake Erie dry.
