Lost Lagoon is an artificial, captive 16.6-hectare (41 acre) body of water, west of Georgia Street, near the entrance to Stanley Park in Vancouver, Canada. Surrounding the lake is a 1.75 km (1.1 mile) trail, and it features a lit fountain that was erected to commemorate the city's golden jubilee. It is a nesting ground to many species of birds, including non-native Mute Swan (whose wing tendons have been clipped to prevent escaping[1]), Canada geese, numerous species of ducks such as mallard ducks and Great Blue Herons.Native food gatherers used the low tide mudflats as a source for clams, and a midden on the north side indicates that a large dwelling once stood there. In the Sḵwxwú7mesh language, the name is Ch'ekxwa'7lech, meaning "gets dry at times". Settlers also built cabins around the lake, which were all removed between 1913 and 1916 during construction of the causeway.[2]The lake was created in 1916 by the construction of the Stanley Park causeway. Prior to its creation, Lost Lagoon was a shallow part of Coal Harbour, now separated by Georgia Street, which itself is an extension of Burrard Inlet.
