Teraina (written also Teeraina, also known as Washington Island – these two names are constitutional) is a coral atoll in the central Pacific Ocean and part of the Northern Line Islands which belong to Kiribati. Obsolete names of Teraina are New Marquesas, Prospect Island, and New York Island. The island is located approximately 4.71° North latitude and 160.76° West longitude. Teraina differs from most other atolls in the world in that it has a large freshwater lake (Washington Lake), an open lens, concealed within its luxuriant coconut palm forest; this is the only permanent freshwater lake in the whole of Kiribati.<!-- this ref only for uniqueness of lake. Do not put behind fullstop! -->
Measuring about NW-SE and SW-NE, it has a land area of about ;
There are two dirt roads around the island's perimeter – an outer (Beach Road) and an inner one (Ring Road). Transport inland is done by boat on artificial canals, rather uniquely for a Pacific island. A navigation light tower and two radio masts stand near Tangkore. What cannot be produced locally is shipped in about twice a year; Although archaeological sites are known to exist on the island, the general lack of fresh water makes long-term human habitation unlikely though more work is needed in establishing the timeline of human use.
Teraina was sighted on 12 June 1798 by the American sealing captain Edmund Fanning of the brig Betsey; he named the island for George Washington but did not attempt to land. The first exploration of the island arrived later with captain Adam Johann von Krusenstern, on a Russian expedition (called then New Marquesas). The island was subsequently claimed under the Guano Islands Act of 1856 for the United States under the name "Prospect Island". Guano was never mined or exported to any notable extent, however; the humid climate prevents the formation of substantial deposits. It was occupied by Captain John English and people from Manihiki in about 1860.
Later William Greig who began planting the island with coconut trees. Eventually the sons of Greig owned the plantation with Father Emmanuel Rougier until he sold his interest to the Fanning Island Limited, and started a coconut plantation on Christmas Island.
