The Maroon Dam is a rock and earth-fill embankment dam with an un-gated spillway across the Burnett Creek that is located in the South East region of Queensland, Australia. The main purpose of the dam is for irrigation of the Scenic Rim Regional Council region.[3] The impounded reservoir is also called Maroon Dam.
The dam is located southwest of Beaudesert. The primary inflow of the reservoir is Burnett Creek, a tributary of Logan River.
Construction of the dam commenced in 1969 and was completed in 1973. The rock and earthfill dam structure is high and long. The 1620e3m3 dam wall holds back the 44300ML reservoir when at full capacity. The dam has a clearance of above full supply level for flood mitigation purposes. This allows for a full operating level at 37100ML.[4] From a catchment area of that lies within the Scenic Rim at the foot of the McPherson Range, the dam creates an unnamed reservoir, with a surface area of . The uncontrolled un-gated spillway has a discharge capacity of,[3] and is situated above the original stream bed. Initially managed by the SunWater, management of the dam was transferred to Seqwater in July 2008.
The reservoir was officially opened on 16 July 1975 by Neville Hewitt, the Queensland Minister for Water Resources. The reservoir contains some areas of standing timber in its upper reaches. It is generally shallow with extensive weedbeds. Drought in February 2003 reduced water levels in the dam to 12%.[5] It was at 18% capacity in November 2003.[6]
Camping is not permitted on the dam's property.[7] Private accommodation is available near the dam.
Fishing and water skiing are popular activities for visitors to the waters held back by the dam. There is a single concrete boat ramp and no restrictions on boat numbers.[7]
The dam is stocked with silver perch, golden perch and bass.[7] Additionally spangled perch are present. The Maroon Moogerah Fish Management Association is the local fish stocking group.[7] A stocked impoundment permit is required to fish in the dam.[8]
