About Andros Island's Barrier Reef
The Andros reef complex is not a true barrier reef system in the strict sense because of the relatively shallow depth of the lagoon and close proximity of the reef crest to the shoreline. It is also not a true fringing reef since it is not set directly against the shoreline. Hence, it is regarded as a hybrid in reef classification.
Andros Island is the largest island of the Bahamas and North Andros is the sixth largest island in the West Indies.It is actually composed of three major islands: North Andros, Mangrove Cay and South Andros. The island has the world's third largest barrier reef; it is affectionately known by Bahamians as the "Big Yard". Andros is the least densely populated of all the Bahamas, with a population of a little over six thousand. Most of these people live on the east coast of the island in the three major towns on the island; Nicholls Town and Andros Town on North Andros, and Congo Town, on South Andros.
About 19 million Litres is shipped to Nassau every day through a pumping station at Morgan's bluff.
On average Andros Island is hit by a Hurricane every two and a half years.
