The Ok Tedi is a river in New Guinea. The Ok Tedi Mine is located near the headwaters of the river, which is sourced in the Star Mountains. Nearly the entirety of the river runs through the North Fly District of the Western Province of Papua New Guinea, but the river crosses the international boundary with Indonesia for less than one kilometre. The largest settlement of the Western Province, Tabubil is located near its banks.
Known as the Ok Tedi River by the Yonggom people who live on its western bank, it was renamed the Alice River by the Italian explorer Luigi d'Albertis. Ok is the word for water or river in the Ok languages family. It is a tributary of the Fly River. Tributaries of the Ok Tedi include the Birim.
The river is extremely fast-moving and has a massive capacity. It is situated on a sand bank, which allows for the river to change course quickly without warning. The sand conditions underneath the river and the extremely high rainfall of the catchment area make it one of the fastest moving rivers in the world. The roar from the river can be heard for many kilometres through the dense jungle of the district.
The pristine river was devastated by the Ok Tedi environmental disaster, an enormous open pit copper/gold mine which discharges waste directly into the river. Until its recent seizure by the Papua New Guinea government the mine was owned by BHP Billiton, an Anglo-Australian multinational mining, metals and petroleum company headquartered in Melbourne, Australia. It is the world's largest mining company measured by 2013 revenues.
