Location and features

On the occasions that there is an overflow from Lake Hindmarsh to the south, water enters Outlet Creek, (Wergaia: Krumelak[3]) which then feeds Lake Albacutya. When full, Lake Albacutya covers 5,500 ha (14,000 acres), is 8 m (26 ft) deep, and holds around 230 gigalitres (8.1×109 cubic feet) of water.

The lake generally fills and empties on a 20-year cycle, the longest dry period on record being 27 years.[5] In 2011 it was reported that the lake had not received any inflow for some years and remained dry throughout the wetter years of 2011–2012.[6]

Being less saline than Lake Hindmarsh, Lake Albacutya supports a denser cover of vegetation during its dry phase.[7]
