The Albury Local Government Area (LGA) contains several catchments that drain to the Murray River, which is the southern boundary of the LGA. Each catchment experiences flooding as a result of rainfall over the area (local catchment flooding) and high flows in the Murray River (riverine flooding), which inundates the southern fringe of each catchment. High levels in the Murray may also increase local catchment flooding.
We have carried out flood studies for the following areas:
- Bungambrawatha Creek, Lavington Drains, South Albury and West Albury
- Thurgoona Creek
- Eight Mile Creek
- Murray River
Bungambrawatha Creek area
The flood study area includes Bungambrawatha Creek, West Albury, South Albury and Lavington Drains. It contains a large section of the Albury urban area. Localised flooding occurs at several locations in the area. The most recent events occurred in February 2001 and September 2005.
Bungambrawatha Creek is the largest creek in the area, running north to south through the town centre and discharging into the Murray River near the Botanic Gardens. During severe storms, the creek can overflow and inundate houses. Flooding can be worse if culverts on the creek are blocked or if the Murray River also has a high water level.
West Albury, South Albury and Lavington Drains are also liable to significant flooding. West Albury receives runoff from the wooded area to its north and conveys the flows through artificial channels. When the capacity of these channels is exceeded, properties in the area may be inundated.
The Lavington Drains area drains runoff from a relatively small catchment; however, the drainage can be insufficient in large storms, leading to flooding of properties and roads.
South Albury is subject to local catchment flooding as well as inundation from the Murray River; however, it is partially protected by a levee.
The Thurgoona catchment is located two kilometres east of Albury town centre and contains three drainage branches, all of which discharge into the Murray River. The catchment contains part of the suburb of Thurgoona as well as the airport and undeveloped pastoral land.
The primary issues identified in the flood study are potential flooding of roads and overland flow in the airport area.
Eight Mile Creek
The Eight Mile Creek catchment drains a relatively large area (65 square kilometres) on the eastern half of the LGA. The catchment has a mild slope and contains four major tributaries that combine to make Eight Mile Creek. The area is mostly lightly wooded pastoral land and contains part of the suburb of Thurgoona.
Records of flooding in the area are relatively limited, probably due to the relatively low level of development in the catchment. A severe flood occurred in January 1974 and there was a minor flood in August 1983.
The Murray River
The Murray River lies on the south boundary of the LGA. The Murray floods as a result of high rainfall over its catchment (largely upstream of the Hume Dam). The most recent major floods occurred in 1974 and 1975.
