The Cedar Pocket Dam is a partially concrete gravity and rock and earth-fill embankment dam with an un-gated spillway located across the Deep Creek in the Wide Bay–Burnett region of Queensland, Australia. The main purpose of the dam is for irrigation,[2][3] where the dam provides regulated water supplies along Deep Creek, a tributary of the Mary River.

Location and features

[edit]

The Cedar Pocket Dam is located about 12 km (7.5 mi) east of Gympie.

The dam wall is 20 metres (66 ft) high and 117 metres (384 ft) long and holds back 735 megalitres (26.0×10^6 cu ft) of water when at full capacity. The surface area of the reservoir is 22 hectares (54 acres) and the catchment area is 17.8 square kilometres (6.9 sq mi). The uncontrolled un-gated spillway has a discharge capacity of 1,110 cubic metres per second (39,000 cu ft/s).[1][3] The dam is managed by Seqwater.[4]
