The Paradise Dam, also known as the Burnett River Dam, is a rock-filled gravity dam across the Burnett River, located northwest and southwest of in the Wide Bay-Burnett region of Queensland, Australia. Built for irrigation, the impoundment created by the dam is called Lake Paradise. ==Location and features== The concrete dam wall is up to high and spans approximately . The dam is named for the ghost town of Paradise, which is now under water following construction. Approval to build the dam was given in 2002.〔 It was constructed on behalf of the Queensland Government between 2003 and 2005. The dam is owned by a government-owned corporation, Burnett Water. Since construction was completed in December 2005, it has been operated by another Queensland government-owned corporation, Sunwater. Construction of the capacity dam cost 240 million to complete and was intended to assist the social and economic growth of the region. The dam is also significant in that it has been the centre of a controversial fishway designed to allow movement of fish upstream and downstream of the dam wall, including the endangered Queensland lungfish. When the Paradise Dam is full, water is released over a stepped spillway followed by a stilling basin. The spillway chute is wide with an smooth ogee profile, ending a few small steps leading to 1V:0.64Hstepped chute with a step height of . The chute is followed by a stilling basin before rejoinging the natural river course. Between 2010 and 2013, the spillway system passed four major events, thus mitigating the effects of flood in the downstream catchment including the city of Bundaberg. The peak discharges were experienced in December 2010, January 2011, January 2013 and in March 2013. 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「Paradise Dam (Queensland)」の詳細全文を読む スポンサード リンク
