Cooloolabin Dam is a concrete gravity dam on Rocky Creek located to the west of Yandina in the headwaters of the South Maroochy River waterway. The main dam wall is 19-metre (62 ft) high and 243 m (797 ft) long, the five saddle dams total 1,100 m (3,600 ft) in length. The dam was completed in 1979 with a capacity of 13,600 ML (11,000 acre⋅ft) and overflowed for the first time in 1988. As part of the seqwater Dam Improvement Program, a section of the spillway was cut away in 2015 to lower the spillway by 3 metres (9.8 ft), reducing the full supply capacity to 8,183 ML (6,634 acre⋅ft).[1][2]
