Dayton, like Cleveland and Cincinnati, has many canal vestiges, but these are not easy to find in heavily urbanized areas. A good place to start is the Carillon Historical Park. This is by no means focused on the Miami& Erie Canal per se, but rather on the history of the Miami Valley from the mound builders to the birth of powered flight. It nicely establishes the importance of the canal in this evolution. There are 23 buildings spread over 65 acres in this facility. A reconstructed canal lock and canal supervisor's house are part of the exhibits.
