Petit lac Ha! Ha! is a freshwater lake in the Ferland-et Boilleau municipality, in the administrative region of Saguenay-Lac-Saint-Jean, in the province of Quebec, in Canada.[1] It is located on the east side of Lake Ha! Ha! into which it drains.
The southern portion of the lake is served by Route 381, which cuts the lake at the peninsula attached to the north shore, then heads northwest to the Northwestern part of Lake Ha! Ha!.
Forestry is the main economic activity of the sector, followed by recreational tourism.
The surface of Petit lac Ha! Ha! is usually frozen from late November to early April. The ice shelf is generally thick enough to allow safe passage from mid-December to late March.
