2023 Map of Saint Lawrence

About this map

The Saint Lawrence River serves as the international boundary between the United States and Canada, defining the northern edge of this Jefferson County landscape. Along the shoreline, deep inlets like Millen Bay, Rose Bay, and Sand Bay carve into the mainland, while islands such as Grindstone Island and Papoose Island dot the river channels. The interior is a mosaic of creek systems, including Wheeler Creek and French Creek, which wind through a network of rural roads such as Macomb Settlement Rd and Co Rd 4.
