Long Description:
Lake Colac is relatively shallow, and has a surface area of 2,668 ha.
With a catchment area of 217 square kilometres.
"Lake Colac is part of the landlocked Corangamite Basin formed by early (Pleistocene and Tertiary) volcanic activity. There are over 1000 lakes and wetlands in the Corangamite Basin many of which have been drained or degraded.
"Volcanic activity blocked the natural outflow of Lake Colac's two tributaries, Deans Creek and Barongarook Creek to the south of Lake Colac and caused the rivers to flow into the basin and leave alluvial deposits. Wind action caused lunettes to form, creating many of these shallow lakes and wetlands.
"Lake Colac is relatively shallow and has a surface area of 2,668 ha. The catchment area of the lake is 217km2. Most of the catchment is made up of volcanic materials whilst tertiary and sand mudstones make up the remainder.
"Volcanic rock and soil has low permeability creating higher runoff than the tertiary sand and mudstone sediments. (Courtesy Colac Otway Shire sign)
