2023 Map of Murphy Islands

About this map

The Saint Lawrence River serves as the dominant geographical feature and international boundary in this 2023 survey of St. Lawrence County, New York. Along this stretch of the Saint Lawrence Seaway, the map reveals a complex riverine environment of named shoals and islands, including Ogden Island and the Murphy Islands. On the American shore, the recreational landscape is anchored by Coles Creek State Park, while the riverbed is defined by submerged hazards such as Goose Neck Islands Shoals and Murphy Shoal. The map captures the modern road network and hydrologic patterns of the northern borderlands, illustrating how the waterway continues to dictate the orientation of regional infrastructure and land use.
