Boondooma Dam is a dam on the Boyne River on the boundary of Boondooma and Proston in the South Burnett Region of Queensland, Australia.^[2] From 1980 to 1983, the dam was constructed across the Boyne River below its confluence with the Stuart River, creating Lake Boondooma.^[3]

It has a capacity of 204 200 ML under the 18.15 square kilometres (4,480 acres) of surface area and has an average depth of 11 metres (36 ft). The dam forms a narrow and deep lake, designed to avoid evaporation,^[4] with one fork containing much standing timber and another having many submerged rocky outcrops.^[5]

The dam overflowed for the first time in May 1983. The lowest level recorded was 0.18% capacity in December 1982, and the maximum of 173.8% (6.17m over the spillway) was recorded in January 2013 as a result of heavy rain from ex Tropical Cyclone Oswald.^[6]
