This large lake is characterized by Baie Sauvage (7.5 km long) located to the southwest of the lake. It has several islands, bays and peninsulas.[1]
With an elongated shape covering 51 km2,this lake stretches over more than 25 km; its width generally varies between 1.5 and 2.5 km. The maximum width of the lake is in the northern part, where the lake forms a long bay stretching southwest to the retaining dam located at the mouth. Grand lac Saint-François is the main head water body of theSaint-François River.This river flows a priori for 10.7 km towards the southwest to join Lake Aylmer atDisraeli,which the current crosses to head south.
Toponymy
editThe name of the lake, which has the same origin as that of the river, evokes the memory ofFrançois de Lausonlord ofLa Citièrewhose land was limited by the river. In 1635, the Compagnie des Cent-Associés granted the seigneury of La Citière to his father Jean. This seigneury was bounded by this watercourse, as indicated in an act of 1638 signed by the governor of Montmagny.
TheAbénaquis name the lake "Ônkobagak", which means "connected lake". Before 2007, the lake was called Lac Saint-François. It was renamed to avoid confusion withPetit lac Saint-François (Ashberham)which is located 1.5 km northwest of it.[2]
In 1815, the vast territory where the lake is located was not yet surveyed as mentioned byJoseph Bouchettein his book “Description topographique du Bas-Canada”. He specifies that at least 12 townships around Lake Saint-François have not yet been surveyed and that the only details, verbal descriptions and drawings are approximate and come from Indian hunters and trappers who had crossed the territory which was still uninhabited; it specifies that there are two lakes connected by a river. Later, in 1917, the dam at the outlet of the lake will raise the level by 7 meters and increase the area to its present size.
Petit lac Saint-François is located 1.5 km northwest of Grand lac Saint-François. Following the request of the riparian municipalities and in order to avoid confusion with other hydronyms using the name “Lac Saint-François”, on May 10, 2007, the name “Grand lac Saint-François” was changed. formalized by theCommission de toponymie du Québecreplacing the designation "Lac Saint-François".[3]
