Lost Lagoon Lake

Lost Lagoon is an artificial, captive 16.6-hectare body of water, west of Georgia Street, near the entrance to Stanley Park in Vancouver, British Columbia, Canada. Surrounding the lake is a 1.75 km trail. The lake features a lit fountain that was erected by Robert Harold Williams to commemorate the city's golden jubilee. It is a nesting ground to many species of birds, including non-native mute swan, Canada geese, numerous species of ducks, such as mallard ducks, and great blue herons. Also many turtles are usually resident on the northern shore.
