Lake Lenthall is a lake created by the Lenthalls Dam in Duckinwilla, in the Fraser Coast Region of Queensland, Australia. The earth and rockfill embankment dam impounds the Burrum River to create a 28,411 ML (23,033 acre⋅ft) man-made reservoir. Due to its relatively small 518-square-kilometre (200 sq mi) catchment area, it takes a short time in moderate rain events to fill Lake Lenthall to 100% capacity.
