Lake Lenthall is a lake created by the Lenthalls Dam in Duckinwilla, Fraser Coast Region, Queensland, Australia. It was named after the pioneering family in the district.^[1]^[2] It was constructed in 1984 on the head waters of the Burrum River and raised by 2 metres in 2007. As a result of a 518 square kilometre catchment it takes a short time in moderate rain events to fill Lake Lenthall to 100% capacity.^[3] It reached its highest recorded level of 30.4m (4.4m over the spillway) in January 2013 as a result of heavy rain from ex Tropical Cyclone Oswald.

The lake has a relatively small surface area of 766 ha, an average depth of 4 to 5 m. Its main purpose is for town water supply for Hervey Bay and surrounding townships within the Fraser Coast Regional Council area.

Fish stock[]

It is stocked with Australian native fish such as barramundi, bass, golden perch and silver perch under the Queensland Governments stocked impoundment permit scheme. Other aquatic species which inhabit the lake include spangled grunter, saratoga, Krefft's turtle, Flinders Ranges mogurnda, rainbow fish, , long finned eel and many more. The lake is home to a myriad of reptiles, insects, bird life and mammals. A significant population of black-breasted buttonquails reside within the dry vine rain forests found on the ridges overlooking Lake Lenthall.
