The Saint Lawrence River and the international boundary with Canada define the northern reach of this landscape, where massive civil engineering projects such as the Long Sault Dam and Snell Lock manage the water's flow. These structures, alongside the Wiley Dondero Canal, highlight the importance of the Saint Lawrence Seaway to the region's 21st-century infrastructure. South of the main river channel, the terrain is shaped by the winding paths of the Grass River and Raquette River, which converge toward the east.
