The Callide Dam is an earth and rock-fill embankment dam across the Callide Creek, located near Biloela, Queensland, Australia. Completed in 1965, the resultant reservoir, Lake Callide, was formed for the purpose of supplying water for irrigation and the thermal Callide Power Station in Mount Murchison. The dam is operated by SunWater.
The dam is high and long. When at full capacity, the reservoir holds at an average depth of over a surface area of , drawing from a catchment. The irrigated area is approximately .
In 1988, gates were added to the spillway to increase the capacity of the dam. SunWater completed a multi-station upgrade program to ensure highest levels of safety for dams of their responsibility. The spillway at the Callide Dam was scheduled to be upgraded in the 'medium-term' range from 2008. In 2021, the spillway gates were to be removed and serviced to address vibration during their operation. In February 2015, the radial spillway gates on the dam automatically opened as a result of heavy rain from Tropical Cyclone Marcia. Severe flooding resulted downstream from the dam. In May 2015, a class action lawsuit against SunWater was launched by residents affected by the flooding; however, it was dropped in February 2016.
The dam's highest recorded level was 102.37% of capacity in March 2017 as a result of heavy rains from ex Tropical Cyclone Debbie.
A Stocked Impoundment Permit is required to fish in the dam.
