Grand Lake as its name suggests is the largest of the seven lakes along the waterway.  It is approximately 13km long and the location where the Shubenacadie River flows from the Lake is about half way down and near the community of Enfield.  In order to maintain the necessary water level in Fletcher Lake, as well as in the stream connecting the two Lakes, a dam had to be constructed at the point where the stream from Fletchers enters Grand Lake.   Because of the difference in the heights of the two lakes Lock 5, was installed  at the western side of the Dam.

Lock 5 is the only fully restored lock on the Canal and it is really worth a visit.  You are able to see all of the features and it is quite clear as to just how the Lock operated.  It is interesting to note, too, that the granite stone used in this Lock was quarried at the Fletcher Lake site and not at the Purcell's Cove Quarry as was the case with the Dartmouth Locks.

Not far from the Lock can be seen an old foundation.  This was the location of the house of the Lock Keeper, William King.   William looked after the vessels as they travelled between the Marine Railway at Portobello and Lock 6, the first Lock on the Shubenacadie River.  

The community around William’s home was often referred to as Lockport.  It was a very active area as it was the location of a mill and a boat yard.  The forest surrounding Grand Lake was the source of lumber for a number of communities including Halifax and Dartmouth and the Canal was used as the means of transportation.  Further to the north are the two Provincial Parks – Laurie and Oakfield.  These are great spots for summer picnics and overnight stays.

For those interested in fishing Grand Lake is a wonderful location if you are looking for bass, pickerel, trout or salmon. And if you are very lucky you may catch a glimpse of Sidney Crosby who has a summer home on the Lake.
