With a surface area of 2,778 hectares and a circumference of 33 kilometres, Lake Colac is the largest natural freshwater lake in Victoria. The lake has an average maximum depth of 2.5 metres, however in recent years the level has been much lower than this.
The lake is part of the Corangamite basin formed by early volcanic activity, which blocked the natural outflow of Deans Creek and Barongarook Creek.
Lake Colac is a popular location for fishing, water activities and other recreation along its shoreline. The area surrounding the lake includes the Colac Botanic Gardens, Bird Reserve, Yacht Club, Rowing Club, Fishing Club, and Meredith Park.
Amenities by the lake in Colac include parking, barbeques, picnic tables, a playground, and public toilets, all located at the eastern end of the foreshore below the Botanic Gardens.
