Located in the Otway Ranges National Park, the West Barwon Reservoir supplies drinking water to the greater Geelong, Bellarine Peninsula and Surf Coast areas. It is the largest reservoir in the Barwon Water region and largest water supply source for the greater Geelong region, supplying more than 80% of the region’s drinking water demand.

At capacity the reservoir holds almost 21,500 million litres of water, enough for approximately six months’ supply of drinking water.
