Buntzen Lake, lake in British Columbia, Canada

Buntzen Lake is a reservoir in British Columbia created by a hydroelectric dam, surrounded by forested ridges and accessible from multiple points. The water body features several coves and shoreline areas that can be reached by road or by water.

Buntzen Lake was originally called Trout Lake and was renamed in 1905 when a tunnel opened from Coquitlam Lake through Eagle Mountain. Coquitlam Lake was dammed, and water flowed 3.6 km through the tunnel to power Vancouver's first hydroelectric plant, Powerhouse No. 1, built in 1903; Powerhouse No. 2 followed in 1914.

The lake is best visited between spring and autumn when roads and paths are easily accessible. A car is helpful for reaching the different access points around the water.

The lake's water was also used to make steam for the gas-powered Burrard Generating Station, which ran until it shut down in 2016. The Halvor Lunden Trail honours a local builder who blazed many routes around the lake in the 1980s and 90s.
