Map of the New Haven & Northampton Canal 

From 1835 to 1847, the longest canal in New England stretched over 86 miles from New Haven to Northampton. Its Connecticut portion was called the Farmington Canal, the Massachusetts portion the Hampshire & Hampden Canal, and the entire waterway the New Haven and Northampton Canal.

This map is an attempt to trace its full extent alongside modern Lidar imagery. With data provided by CT ECO and MassGIS ruins of the old canal can be explored, even through heavy forests and hillsides. For the majority of the route where there is no trace Carl Walter's definitive maps of the canal have been referenced. See sources.

Data is currently available as vector lines and points of interest. It does not account for dimensions of the canal, basins, or sections. This is a work in progress.
