Dowker Island is an uninhabited island in Lake Saint Louis, a widening of the Saint Lawrence River south of Montreal Island, Quebec. It is in the municipality of Notre-Dame-de-l'Île-Perrot[1] which intends to preserve its natural state.[2]
The island is about a kilometre in length and breadth. Its surface geology is undifferentiated till deposits.[3] It is low-lying, mostly in a 100-year flood area,[4] and contains a muskrat habitat.[5]
Then known as one of the îles Sainte-Geneviève (now Dowker, Madore, and Daoust),[6] the island was granted to governor of Montreal François-Marie Perrot by Jean Talon, in 1672, along with the île Perrot.[7] It was acquired in 1897[7] by Leslie Rose Dowker (unknown-1945),[8] who shortly afterward became Mayor of Sainte-Anne-du-Bout-de-l'Île, now known as Sainte-Anne-de-Bellevue.
It is the site of a ruined stone house as well as a former navigational aid light.[9]
In older documents,[7] as late as the 1966 topographic map of Sainte-Anne-de-Bellevue, it is named Lynch Island.
