The Lockyer Creek is a creek located in South East Queensland, Australia. A tributary of the Brisbane River, the creek is a major drainage system in the Lockyer Valley. Rising on the eastern slopes of the Great Dividing Range, the creek flows generally north-easterly for more than before it reaches its confluence with the Brisbane River north-northeast of , and downstream from the Wivenhoe Dam. The creek is named after Edmund Lockyer.〔 ==Course and features== Draining parts of the western Scenic Rim, the creek's headwaters are in the Main Range National Park, a small sub-section of the Great Dividing Range. Its tributaries drain the slopes east of Toowoomba and areas to the north of . The total stream length of the Lockyer Creek network is . The total catchment area is , and covers nearly one quarter of the total catchment area of the Brisbane River. O'Reillys Weir is located about upstream from the creek's confluence with the Brisbane River. Approximately upstream from the junction of Lockyer Creek and the Brisbane River is the Wivenhoe Dam. Tributaries flowing into Lockyer Creek include Flagstone Creek, Sandy Creek, Alice Creek, Laidley Creek, Tenthill Creek, Murphys Creek and Ma Ma Creek.〔 Lower areas of the catchment have been cleared for intensive agriculture.〔 Upper parts of the catchment remain mostly forested,〔 partially protected within Lockyer National Park formerly known as White Mountain State Forest. Bushfires, soil protection, water quality and flood management are the main resource management issues for the waterway.〔South East Queensland Regional Strategy Group, ''Strategic Guide to Resource Management in South East Queensland'', November 2000. p 102.〕 The creek is significantly degraded. The poor conditions have resulted in unstable stream banks and gully erosion from the removal of riparian vegetation.〔 There are a total of nine major private and public water storages within this drainage system, including Atkinson Dam, Bill Gunn Dam and Lake Clarendon.〔 The Lockyer Creek valley had been one of the driest catchments in Queensland during the recent droughts in Australia. 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「Lockyer Creek」の詳細全文を読む スポンサード リンク
