The main purpose of the dam is for supply of potable water for the Sunshine Coast region. The impounded reservoir is also called Wappa Dam. The dam and most of the reservoir are within Kiamba with the most northerly part of the reservoir in Cooloolabin, both in the Sunshine Coast Region.
Location and features

The dam is located 8 km north-west of .
Completed in 1963, the concrete dam structure is 24 m high and 138 m long. The 12 e3m3 dam wall holds back the 4614 ML reservoir when at full capacity. From a catchment area of 69.7 km2 with a mean annual rainfall of approximately 1700 mm that includes much of the Maroochy River, the dam creates an unnamed reservoir with a surface area of 74 ha. The ungated spillway has a discharge capacity of 1420 m3/s. The accompanying water treatment plant is also managed by SEQ Water.
Recreational uses
Recreational use of the lake and its surrounding bushland reserve is severely limited, with prohibited recreational activities including swimming, water skiing, diving, mountain biking, horse riding, canoeing and kayaking, camping, and bushwalking. Picnic facilities are available at four locations around the dam,
