Abstract Enterprise Pit Lake is a water‐filled mining void located in Australia’s wet/dry tropics south of Darwin in the Northern Territory (13°49.6′S, 131°49.8′E). In the mid‐1990s, the void was rapidly filled by the artificial diversion of the nearby Pine Creek watercourse. Profile data and surface water quality data were collected in the lake on a monthly basis from November 1998 to October 1999. Analysis of this data showed that Enterprise Pit Lake was strongly stratified for most of the year with deep mixing occurring once during the middle of the cool, dry season (August, 1999). The relatively small volume of its epilimnion and its low productivity allowed significant oxygen concentrations to remain in the hypolimnion of the lake when it was strongly stratified. Low pH values in a layer of water with a depth of approximately 35 m and located in the lake’s hypolimnion might be associated with several factors, including enhanced sulphide oxidation on the walls of the pit in this region.
