[3] The town of Blue Sea is in the centre of what is known as the Upper Gatineau region and is surrounded by a number of other lakes, rivers, ponds, and wetlands — and true wilderness areas.

Like so many other areas of Quebec, Blue Sea grew and prospered because of the forest industry, which in turn was dependent on the abundant waterways of the region, especially the Gatineau.

According to legend, a monstrous snake-like animal with a horse head used to live in this lake.

His "absence" has been explained by the increase of tourism in the region and, hence, the number of motorized boats travelling on the lake.

The Algonquin of Maniwaki called this monster "Misiganebic" or Grand Serpent, who supposedly cut a trail between Blue Sea and Cedar Lakes and would have manifested itself in several surrounding lakes and rivers.
