Tul,
that appears to be a man-made feature, though I'm sure women helped, too...where I am is a naturally formed phenomenon. But may I suggest that based on this info, your guess would fit well into our "The Longest Thread":
The Pangalanes is a chain of sweet water lakes and lagoons parallel to the coast of the Indian Ocean, separated by a narrow stretch of land. The lakes are connected by a man-made channel system that forms an inland waterway from Tamatave through to Farafangana, making it the longest canal in the world covering a distance of 600km.
