Shortly after the canal was constructed, J. Norris built a mill at this canal lock. It was called the Baltimore Mills. The mill was powered by water from the canal. The water was channeled into a millrace, which flowed it towards the mill, where it was used to turn the waterwheel.

This forgotten and rarely seen canal lock is hidden in the woods just outside Baltimore. Piles upon piles of trash and barbed wire have been disgracefully dumped inside.
