The Complete List of Rivers in the Solomon Islands

The rivers of the Solomon Islands weave through volcanic highlands, mangrove fringes and coastal plains, supporting villages, fisheries and unique habitats. These waterways are often short but ecologically important, and knowing their locations helps with travel, research and conservation planning.

There are 50 Rivers in Solomon Islands, ranging from Aola to Zongga. For each entry you’ll find below Island/Province, Coordinates (lat,long) and Length (km), organized so you can scan locations, map points and compare sizes quickly — you’ll find below.

How reliable are the coordinates and length measurements listed here?

Most coordinates and lengths are based on a combination of official maps, satellite imagery and local surveys; small rivers may have approximate lengths and rounded coordinates, so use this list as a starting point and verify critical details against primary sources or recent satellite data.

Can I use this list for mapping or academic work?

Yes — the list is intended for reference and preliminary mapping, but for formal publications or navigation, corroborate with up-to-date government datasets or field measurements and cite the original sources you consult.
