Monocacy Canal Maps

In 1829 The Frederick County Canal Company explored the potential of developing a branch line extending from the C & O Canal which was under construction. The proposed Monocacy Canal was surveyed by Dr. John Martineau, an engineer from the C & O Canal Company. In the summer and fall of that year Martineau finalized the documentation associated with the proposed Monocacy Canal. The survey shows two possible routes following closely along the river's edge. The northernmost point of the Monocacy Canal would have begun near Creagerstown and followed the River south until it met up with the C & O Canal near Dickerson. Although Frederick did not pursue canal building, which would have left an indelible mark on the local landscape, the resulting maps from 1829 offer a rare and detailed glance of the rural landscape surrounding Frederick. Below is a partial set of the 1929 Monocacy Canal survey.
