The Barham River has a short wide floodplain south of Apollo Bay with well defined terraced margins. Drilling into the Barham River sediments has shown over 60 metres of alluvial fill. This indicates the depth of river incision during low sea level episodes in the Pleistocene. The alluvial surface is now drained and cleared but near Mount Bay, there are lagoons which are abandoned tidal channel meanders. These developed during earlier Holocene times, before the Barham entrance was enclosed by the sand barrier spit that extends north from Marengo. The barrier also encloses a now dry lagoon, the inner edge of this being the degraded low bluff near the Apollo Bay landing ground.
State. These are the largest abandoned tidal meanders of any stream in Western Victoria. The sequence of barrier, lagoon, bluff, infilled estuary and meanders demonstrates a classic case of river infilling and modification by marine and estuarine processes.
