The Solomon Dam is an earth-filled embankment dam located 42 kilometres (26 mi) east of Ingham, in Far North Queensland, Australia. Together with the Francis Creek Dam, the Solomon Dam is a main source of potable water for the Great Palm Island.
Completed in 1977, the dam is 17 metres (56 ft) high and 408 metres (1,339 ft) long. The resultant 487-megalitre (395 acre⋅ft) reservoir draws from a relatively-small catchment area of 4 square kilometres (1.5 sq mi). The dam is operated by the Aboriginal Shire of Palm Island.
After a sustained drought, in 2016 it was reported that Council was considering replacing the dam with a desalination plant. A $7-million grant for a temporary desalination plant was approved by the Queensland Government in February 2016. Plans for a permanent solar desalination plant were unresolved, as of March 2026[update].
Scientific studies have claimed that the dam is impacted by cyanobacteria.
