Geography
Saint Joseph Atoll is located only 2.3 kilometres (1.4 mi) east of the eastern part of D'Arros Island, but it is a separate geographical unit, separated by 60–62 metres (197–203 ft) deep water of a 1 kilometre (0.62 mi) wide channel, which is deeper than much of the Amirantes Bank. The land area of the Atoll occupies 1.21 square kilometres (0.47 sq mi). The main Saint Joseph island is of crescent shaped, flat coral sand cay, 2.2 kilometres (1.4 mi) long and with average 0.4 kilometres (0.25 mi) wide, and nowhere higher than 3 metres (9.8 ft). The tree tops are about 24 m high.
Coral reefs
The Atoll stands on a detached patch coral reef similarly orientated, with maximum dimensions of 6.6 kilometres (4.1 mi) and 4.4 kilometres (2.7 mi). Its total area is 22.53 km2, of which 11.74 km2 comprises the peripheral reef flat, 4.8 km2 the interior lagoon, and only 1.39 km2 the land area of all islets. Depths of 500 m are found only 1.5 km east of the reef edge, and of 1000 m one kilometer further east.
Lagoon
The lagoon is completely enclosed by the surrounding reef. At low water it drains over a narrow sill, Passe Lerein Fin, at its western end. The lagoon has a maximum depth of 6.4 m. Other soundings range from 2.1 to 3.7 m. The peripheral reefs, in addition to being exceptionally wide, are covered (except on the west side) with mobile sand. Inter-tidal sand sheets are encroaching on the margins of the lagoon on its windward side, which is marked for much of its extent by a discontinuous linear sandbar. There are no growing reefs in the lagoon.
List of islets
The atoll has 13 sandy islets: the three larger ones along the northeast and east shore, which are covered by coconut plantations, and the remaining ones in the south:
Administration
The island belongs to Outer Islands District.[5]
Demographics
The atoll is currently uninhabited. it hosted a small population of 10, which now moved to D'Arros Island. There are several ruined buildings on the main island of St. Joseph, near the cultivated area at the western end.
Transport
You can reach the atoll with flights to unpaved airstrip (ICAO: FSDA).
