The embankment is approximately 255 metres (837 ft) long and has a 60.9 metres (200 ft) long spillway. In addition to the main embankment, there are two saddle dams. The reservoir has a storage capacity of 11,830 megalitres (15,470,000 cu yd).^[1] The reservoir is surrounded by the Paluma Range National Park, but does not form a part of the park.^[3]

Water decanted from the dam is piped 4.5 kilometres (2.8 mi) to the Crystal Creek catchment, on the eastern slopes of the Paluma Range. This water supplements natural flow in Crystal Creek, which is drawn from for supply of water to the city of Townsville. Maximum outflow from the dam is 43.2 ML/day.^[1]

Paluma Dam was constructed between 1957 and 1958. The original storage capacity was 10,273 ML. This was increased to 11,496 ML in 1981 and then to 11,830 ML in 2020. These increases in capacity were achieved by adding flashboards to the spillway.^[2]

Paluma Dam can be accessed via Paluma Dam Road. The lake and the surrounding national park are used for recreational activities such as camping, hiking, swimming and non-motorised boating.
