Carnegie Bay Marina's location provides a central point from which to explore the beautiful Thousand Islands region. Conveniently located in the secluded Carnegie Bay, just off the beautiful St. Lawrence River Seaway, the marina is within walking distance of downtown Alexandria Bay.

Following the flooding of the river in 2019, the marina suffered significant damage. This is when the owners consider new plans for improving the facilities. First a new boat launch was built, then major dock repairs and upgrades. Structurmarine has built more than fifty new berths in the marina. Not only were the docks reinforced and raised, but they were also made high enough to allow dockage and prevent damage of future high-water levels.

The project also includes a 20' long aluminum access walkway. Places that can accommodate boat holds from 20' to 40'. The anchoring method is track beam for this full-service marina, which has a system that remains in the water during the winter.
