The City of Ballarat has a history of flooding which is mainly due to flash flooding after high intensity rainfall often associated with thunderstorms. Other flooding is associated with flooding from rivers and creeks overflowing after prolonged rainfall.
In December 1991 severe thunderstorms brought intense rainfall, resulting in the largest flood events this century for both Ballarat East and Central Ballarat. In central Ballarat, Gnarr Creek caused flood and stormwater damage to homes and businesses, with the Lydiard Street area the worst affected.
More recently, several areas of Ballarat, including Miners Rest, Ballarat East, Delacombe and Alfredton, experienced flooding in January 2011 after prolonged heavy rainfall fell across Victoria.
The lead time to respond to a flood event may be limited. All households and businesses at risk of flooding should develop an emergency plan and beware of their flood risk.
Households and business should refer to their Local Flood Guide (below).
