Buntzen Lake Professional Review and Guide
"Lake Beautiful, as this body of water was originally called, was dammed in 1903 as part of Vancouver’s first hydroelectric power project. Later, a tunnel was made through Eagle Mountain (the outflow can be seen at North Beach) bringing water from Coquitlam Lake, and a power plant was built on Indian Arm.
By this time the reservoir had been renamed after the general manager of B.C. Electric, Johannes Buntzen, a change that could not detract from the beauty of the 5-km (3-mile)–long lake lying between the forested slopes of Buntzen Ridge and Eagle Mountain, above Indian Arm. Highlights: Lake, forest, mountains; fungi; sapsuckers. Terrain: Gentle ups and downs. Well-groomed forest trail, mostly gravel."
