Fly River Delta, Papua New Guinea - May 12th, 2009

Fly River Delta, Papua New Guinea - May 12th, 2009

The Fly, at 1,050 kilometres (650 mi), is the second longest river, in Papua New Guinea. It rises in the Star Mountains, and crosses the south-western lowlands before flowing into the Gulf of Papua in a large delta. Here, golden tan sediments pour from the river into the gulf.

The estuary of the Fly River is 56 km wide at its entrance, but only 11 km wide abreast Kiwai Island, which may be considered as being the river mouth. Above this island the river gradually contracts to a width of 1.6 kilometers or less.

The river delta is studded with low and swampy islands covered with mangrove and nipa palm.  The land on both sides of the estuary is of the same character.

The islands in the estuary, on which there are villages and cultivated areas, are flat and  covered with a thick, fertile alluvial soil.

The largest islands are Kiwai, Wabuda, Domori, Purutu, Aibino and Mibu, although only the former three are inhabited.
