The barque Endeavour also made an unscheduled stop at the islands when it shipwrecked there in late November 1835. Captain Lachance lit a signal fire on the islands’ highest point, where it was eventually seen by Riviére-du-Loup river pilot, Joseph Pelletier. Pelletier organized a rescue team of eight men, with two canoes, who paddled the twelve miles in freezing conditions. By the time they arrived, fourteen men had perished from starvation and exposure, but Pelletier received a a gold medal from the merchants of Quebec for rescuing the fifteen others.
Almost thirty years later, in 1862, another “signal fire” was lit on the archipelago: the Pot a l’Eau-de-Vie Lighthouse.
Designed by John Page and constructed under the direction of Louis Déry, the lighthouse, built on the southeastern tip of Pot du Phare, was a twin to the light on l’Île du Long Pélerin (Long Pilgrim Island). The tower and dwelling are combined in the form of a thirty-foot-six-inch square white clapboard structure with a 9.15 metre (30 foot) high cylindrical brick tower rising from the center. The dwelling’s red roof is built around the tower and slopes down on four sides. In 1884 a rectangular annex, used as a storehouse and summer kitchen, was added to the lighthouse. The station's wooden oil shed was also painted white with a red roof.
A fixed white light was exhibited from a fourth-order Fresnel lens, installed in the tower’s lantern room that had a diameter of five feet ten inches and was fitted with panes of glass measuring 43 x 28 1/2 x 1/2 inches. The mammoth flat-wick lamp used inside the lens consumed roughly seventy gallons of oil per season.
The Pot a l’Eau-de-Vie Lightstation never had a fog alarm. The channel in the vicinity is narrow and surrounded by shoals, and in thick fog, heavy draught vessels could not go through it with any degree of safety. Rather, they were compelled to anchor near the approaches to the channel and wait for visibility to improve. Given the configuration of the land near the lighthouse, the Department of Marine thought that a fog alarm “would be subject to so many varieties of reflection and sound shadows from unequal heating of the atmosphere in patches, that its action could neither be foretold nor depended upon, and it would be extremely difficult to locate the sound, as we have found at other fog-alarm stations where there were outlying shoals.”
Roger Dubé was serving as keeper when the light was automated in 1964. In 1975, a light atop a forty-one-foot (12.5-metre) square steel skeletal tower took over the role of the lighthouse, and in 1978 the lens was removed from atop the lighthouse and its lantern room was removed as it blocked the light on the modern tower. The current yellow light flashes once every two seconds at a focal plane of 119 feet (36 metres).
In 1979, a handful of biologists united to preserve the ecological richness of the Lower St. Lawrence Islands. Under the direction of Université Laval biologist Jean Bédard, they founded the nonprofit organization, Société Duvetnor Ltée. Bédard had come to love the region in the early 1970s, when he was studying the unusual eider behaviour of crèche formation, where an extended family of ducklings and females from different nests spontaneously come together under threat of a predator.
Société Duvetnor Ltée soon purchased Les Pèlerins Archipelago and several small islands and then, in 1986, Île aux Lièvres. Duvetnor obtained a lease for the Pot a l’Eau-de-Vieu Lighthouse, and in 1989 renovated the structure using historic photographs and John Page’s original architectural plans. On August 20, 1989, a newly fabricated copper lantern room was hoisted atop the tower, restoring some dignity to the neglected structure. That same year the society opened up Île aux Lièvres and Pot du Phare to visitors.
Duvetnor raised funds to restore and maintain the lighthouse using a novel idea proposed by Bédard. Employees would collect eiderdown by hand from 12,000 nests on the local islands during a two-week sweep each spring, and the prized down would then be cleaned and sold in Europe for manufacturing comforters and clothing. The first year the society was formed, $10,000 worth of down was gathered, and this amount was doubled the following year. In 2007, the group sold seventy kilograms of down.
Îles du Pot à l’Eau-de-Vie are uninhabited, apart from birds and seals, but visitors can spend the night at the lighthouse, a Recognized Federal Heritage Building, and climb the thirty-one steps of the beautifully restored spiral wooden staircase to the top of the tower to see for themselves the region that captivated Bédard.
