Portneuf Range Rear Lighthouse

The Portneuf Range Rear structure is a steel skeletal mast reaching 14.5 meters in height. It displays a daymark that is orange with a black vertical stripe. Located in Portneuf, Quebec, on the St. Lawrence River, this light functions with a forward range light to direct vessels within a specific channel. The light source is positioned at a focal height of 41 meters, with a reported coverage distance of 17.2 nautical miles. Access to the grounds is permitted, but the structure itself is not open to visitors. The closest port is Portneuf, situated 0.9 kilometers distant.

Why it matters: This rear range light, aligned with its front counterpart, serves as a primary reference point for vessels navigating a defined channel on the St. Lawrence River. Its function is to mark the safe passage, preventing contact with underwater hazards and ensuring the continued movement of maritime traffic in this significant Canadian waterway.
