Abstract:

Flood plain landforms.

Access:

From Maffra Lake Park Road or Bellbird Corner Road.

Ownership:

Private land.

Geomorphology:

The present flood plain of the Macalister River lies between higher level terrace deposits east of Lake Glenmaggie. The flood plain is of the alluvial meander type with a highly sinuous channel form giving rise to numerous cut-off meanders. These display various stages of swamp reclamation. Fences and point bar deposits are prominent on those meander reaches not subject to intensive agriculture.

Significance:

Regional. The extent of meander cut-off development is much higher than for other East Gippsland streams. This is possibly due to the greater length of flood plain on the Macalister River.

Management:

The flood plain has been extensively modified by agricultural activities. However, continued course changes by the Macalister River should maintain the development of the fluvial features on the flood plains.
