The Callide Dam is an earth and rock-fill dam which was constructed in 1965 to supply water for the Callide Power Station in Mount Murchison near Biloela in the state of Queensland, Australia.[2] The impoundment of the dam is Lake Callide, which holds 136,370 megalitres (3.603×1010 US gal) at an average depth of 10.5 metres (34 ft) and a surface area of 1,240 hectares (3,100 acres) at full capacity.

History

In 1988, gates were added to the spillway to increase the capacity of the dam in 1988.[3] SunWater, the water supply and services company, has undertaken a multi-station upgrade program to ensure highest levels of safety for dams of their responsibility. The Callide spillway was scheduled to be upgraded in the 'medium-term' range from 2008.[3] In 2021, the spillway gates were to be removed and serviced to address vibration during their operation. [4]

In February 2015, the radial spillway gates on the dam automatically opened as a result of heavy rain from Tropical Cyclone Marcia.[5] Severe flooding resulted downstream from the dam.[6] In May 2015, a class action lawsuit against the dam operator SunWater was launched by residents affected by the flooding. The class action was dropped in February 2016.[7]

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.

Fishing

A Stocked Impoundment Permit is required to fish in the dam.[8]
