Before QC-138 reached Natashquan, the only link to the village was by water, and navigational aids were thus critical in helping guide mariners into the harbour. Three different light stations were built over the years near Natashquan.
The first lighthouse, established in 1906 on rocky Île Joncas, just offshore from the village, was known early on as Natashkwan Harbor Lighthouse. The Department of Marine published the following description of this structure in 1906:
A lighthouse established in Little Natashkwan harbour was put in operation on July 1, 1906. The lighthouse stands on the west extremity of the island at the entrance to the harbour, replacing the beacon of skeleton steelwork formerly maintained there. It is a wooden tower, square in plan, with sloping sides, painted white, surmounted by a square wooden lantern, painted white, with roof red. It is 32 feet high from its base to the ventilator on the lantern. The light is a fixed white dioptric light of the seventh order, elevated 33 feet above high water mark and visible 11 miles from all points of approach. The tower was erected by day’s labour under the supervision of the Quebec agency and cost $1,578.
Elie Landry was hired as the first keeper of the light, and in 1910, an oil and shelter shed was added to the island.
In 1912, work began on a concrete tower on Natashquan Point, roughly thirteen kilometres southeast of the village, to serve as a coastal light. In addition to the lighthouse, a dwelling, oil store, and boathouse were built at the station. The white, hexagonal tower with its six buttresses and red lantern room was equipped with a fourth-order, triple-flash lens and was placed in operation in 1914. The lighthouse stood forty-six feet tall and had a focal plane of sixty-six feet above the Gulf of St. Lawrence. The tower was erected by day’s labour under the direction of C. Carbonneau and cost $15,401.18. W. Landry was hired as the first keeper of Natashquan Point Lighthouse.
A diaphone fog alarm was added to Natashquan Point Lighthouse around 1931 to help mariners navigate during periods of limited visibility.
Realizing that Natashquan Point Lighthouse was threatened due to erosion of the bank on which it stood, the Coast Guard erected a thirty-foot-tall skeletal tower nearby in 1992 to display a light. Three years later, the hexagonal, concrete tower toppled over the bluff in the spring of 1995. Natashquan Point Light was discontinued around 2006, but the remains of the concrete tower can still be seen on the beach at the point.
Little Natashquan Lighthouse on Île Joncas was demolished during a storm in the winter of 1969 and was subsequently replaced by a thirty-foot-tall, skeletal tower. The light on Île Joncas and the harbour’s range lights, known now as Petite Natashquan Range, remain active today.
