FLOOD INFORMATION FOR TUGGERANONG CREEK OVERVIEW Tuggeranong Creek is one of eight main water catchments in the ACT. Catchments are areas, usually bounded by hills, where the rain drains into the soil and streams and feeds into a river, creek or drainage line. In Canberra’s past, many natural waterways were converted into the familiar concrete storm drain channels as new areas of the city were developed. The Tuggeranong Creek catchment is the most southern of Canberra’s catchments, extending from the Monaro Highway, south-east of Theodore, to the Lake Tuggeranong outlet at Athllon Drive. The catchment covers approximately 69 square kilometres and spans approximately 5 kilometres north–south and 13 kilometres east–west. The catchment is highly urbanised (currently 72%), with some forested areas on the eastern fringes. Residential development began in the early 1970s. Ongoing development, including infill and redevelopment, continues. This information sheet outlines information about past and potential flooding for the Tuggeranong Creek Catchment and what is being done to mitigate the risk of flooding. The risk of flooding in Canberra is low.

D R V E KAMBAH A R I K D E N F O L O L R H T D A Flood maps have been developed for each catchment and reviewed by D R I V E WANNIASSA independent experts for accuracy. The maps highlight flow paths, flood LAKE TUGGERANONG ACT depth and the potential hazard posed by floodwaters arising from Canberra’s channels, creeks and rivers. This mapping is complemented by this information FADDEN NSW E sheet and a list of questions and answers. The updated maps show the areas V I R D E R I N D A L E which could be affected by flooding from waterways in Canberra during a major OXLEY flood event, known as a 1% Annual Exceedance Probability (AEP) flood. This GREENWAY means that in any given year there is a 1% chance of this type of flood occurring.

TUGGERANONG CREEK CATCHMENT FLOOD HISTORY RICHARDSON The Tuggeranong Creek catchment is not prone to frequent and extensive flooding.
