The main purpose of the dam is for potable water supply of the Redland City in Brisbane.〔 The impounded reservoir is called Tingalpa Reservoir. ==Location and features== The dam is located between the suburbs of Capalaba, Chandler and Burbank, approximately southeast of Brisbane. The primary inflow of the reservoir is the Tingalpa Creek, not far above its confluence with the Brisbane River. The dam is one of a number of dams connected to the South East Queensland Water Grid, and the dam provides approximately 20% of the water supply for Redland City. Completed in 1968, the earthfill dam structure is high and long. The dam wall holds back the reservoir when at full capacity. From a catchment area of that includes much of the northern slopes of the Venman Bushland National Park, the dam creates Tingalpa Reservoir, with a surface area of . The controlled gated spillway has a discharge capacity of .〔 Initially managed by the Redland City Council, management of the dam was transferred to Seqwater in July 2008 as part of a water security project in the South East Queensland region, known as the South East Queensland Water Grid. In 1984, the dam wall was raised and gates were installed,〔 and in 2014, work began on improving the safety of the dam after Seqwater completed a major investigation of its operating dams, which includes draining the dam to approximately 50% capacity. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Leslie Harrison Dam」の詳細全文を読む スポンサード リンク
