The Baroon Pocket Dam is a rock and earth-fill embankment dam with an un-gated spillway across the Obi Obi Creek, in North Maleny, Sunshine Coast Region, in South East Queensland, Australia. The main purpose of the dam is for potable water supply. The resultant reservoir is called Lake Baroon.
Just below the dam is Obi Obi Gorge, one of the few remaining places left where the Mary River cod maintains a wild population. After its initial filling, the dam reached its lowest level between December 2002 and February 2003 at 50% capacity.
Located 7 kilometres (4.3 mi) north of Maleny in the Sunshine Coast region, the dam wall was completed in 1989 over the Obi Obi Creek, Small Creek and several unnamed watercourses.
The dam wall is 58 metres (190 ft) high and 370 metres (1,210 ft) long and holds back 61,000 megalitres (13×109 imp gal; 16×109 US gal) of water when at full capacity. The surface area of the reservoir is 380 hectares (940 acres) and the catchment area is 72 square kilometres (28 sq mi). The uncontrolled un-gated spillway has a discharge capacity of 1,013 cubic metres per second (35,800 cu ft/s).
Baroon Pocket Dam's primary use is for town water supply for Maroochy and Caloundra. An intake tower allows water to flow from the dam through a 2.5-metre (8.2 ft) wide, 2.5-kilometre (1.6 mi) long tunnel under the Blackall Range. Water is then distributed by UnityWater for a range of purposes. The dam and catchment is managed by Seqwater.
