Plaque Text

The canals at Farran's Point, Rapide Plat and Galops were known collectively as the Williamsburg Canals. All three were built in the period 1844-56 on the north side of the St. Lawrence to form part of the Great Lakes navigation system. Farran's Point Canal was 1.2 km long with a single lock; the Rapide Plat was 6.4 km long and had two locks; the Galops and Iroquois canals, together known as the Galops Canal, covered 12 km and had three locks. Ascending vessels used all three canals, while those descending used only the Galops. These canals disappeared with construction of the St. Lawrence Seaway in 1959.
