shallow body of water separated from larger body of water by a barrier
A lagoon is a shallow body of water separated from a larger body of water by barrier islands or reefs. Lagoons are commonly divided into coastal lagoons and atoll lagoons. They have also been identified as occurring on mixed-sand and gravel coastlines. There is an overlap between bodies of water classified as coastal lagoons and bodies of water classified as estuaries. Lagoons are common coastal features around many parts of the world.
- Of course the Neverlands vary a good deal. John’s, for instance, had a lagoon with flamingoes flying over it at which John was shooting, while Michael, who was very small, had a flamingo with lagoons flying over it.

- If you shut your eyes and are a lucky one, you may see at times a shapeless pool of lovely pale colours suspended in the darkness; then if you squeeze your eyes tighter, the pool begins to take shape, and the colours become so vivid that with another squeeze they must go on fire. But just before they go on fire you see the lagoon.

- Enki knit together the marshlands, making young and old reeds grow there; he made birds and fish teem in the pools and lagoons; ... he filled the reed-beds and marshes with Fish and Bird, indicated to them their positions and instructed them in their divine rules.

- By hand Enten guided the spring floods, the abundance and life of the Land, down from the edge of the hills. He set his foot upon the Tigris and Euphrates like a big bull and released them into the fields and fruitful acres of Enlil. He shaped lagoons in the water of the sea. He let fish and birds together come into existence by the sea.
