Over 2000 individual assets are maintained along the rivers and floodplains.
An embankment providing a reduction in in flood damages to towns in moderate and major flood events and the rural areas in minor events.
Drainage Channel (or drains)
Control discharge of floodwaters from the river spilling into defined floodways.
Control and diversion banks
Reduce the potential damage by controlling the speed, direction and depth of floodwaters. These are located on the Bolwarra, Oakhampton, Swan Reach and Raymond Terrace floodways.
Prevents backflow from the river as water levels rise during flood events and releases water from drains and creeks after flood waters recede.
Part of the natural floodplain allowing diversion of floodwaters away from the main river channel during a flood and which is often a naturally defined channel. If these areas are blocked they can cause a significant change in flood flow, direction and levels, affecting other areas.
Bank stabilisation and protection works
Protection works stabilise and protect surrounding river banks from erosive flood waters, which in turn protects the levee assets.
River or stream banks without vegetation will continue to be unstable if the toe of the bank, where the levee meets the original surface foundation, continues to wash away.
Vegetation within the levee protected zone is limited to grass or low ground coverage. OEH does not permit planting of trees or shrubs within the protected zone.
