Lac Stukely is a natural lake of approximately 4 square kilometres (1.5 sq mi) nestled within the Eastern Townships of Quebec, Canada, sitting at an elevation of 285 metres (935 ft) above sea level. The lake stretches 5.3 km (3.3 mi) in length and reaches up to 1.6 km (0.99 mi) in width, with a maximum depth of 32 metres (105 ft). A significant portion of its shoreline falls within the boundaries of Mont-Orford National Park, with the surrounding municipalities of Orford, Bonsecours, and Eastman bordering its waters. The lake sits at the head of the Saumon River watershed, which gives it a notably long water retention time relative to its size — a characteristic that influences water quality, temperature stratification, and fish habitat throughout the seasons. The park setting provides a scenic backdrop of forested hills and the iconic Mont Chauve, making this one of the more picturesque fishing destinations in the Eastern Townships region.
