At Ok Tedi waste rock from the mine and, until relatively recently, the tailings arising from concentrating the ore have been dumped into creeks draining into the Ok Tedi, a river which in turn drains into the Fly River and thence to the Gulf of Papua (Bolton et al. 2009).
The greatest danger of tailings ponds is dam failure, with the most publicized failure in the U.S. being the failure of a coal slurry dam in the West ia Buffalo Creek Flood, which killed 125 people; other collapses include the Ok Tedi environmental disaster in New Guinea, which destroyed the fishery of the Ok Tedi
