Googong Reservoir, also known as Googong Dam, is a significant freshwater impoundment located just over the New South Wales and Australian Capital Territory border near Canberra. Constructed in the late 1970s on the Queanbeyan River, it serves as a crucial backup water supply for the region. The reservoir is characterized by its deep, clear waters, with the main basin plunging to depths exceeding 60 meters. While historically a mixed fishery, it has evolved into a stronghold for native Australian species, offering a challenging and rewarding environment for anglers focused on trophy fish. Access is managed with strict environmental protections, and the waterway is restricted to non-motorized or electric-powered craft only.
