4. Swamp/Lake - "Eastern Downs"

This information has been developed from the publications:

  • Sites of Geological and Geomorphological Significance in Central Gippsland (1981) by Neville Rosengren, M.S McRae-Williams and S.M Kraemers,
  • Sites of Geological and Geomorphological Significance on the Coast of Port Phillip Bay and in the Catchment of Westernport Bay (1984, 88) by Neville Rosengren.
  • Sites of Geological and Geomorphological Significance in the South Gippsland Marine and Coastal Parks (1989) by Neville Rosengren.
Geological heritage sites, including sites of geomorphological interest and volcanic heritage sites, are under regular revision by the Geological Society of Australia, especially in the assessment of significance and values. Reference should be made to the most recent reports. See the Earth Science Heritage (external link) section of the Geological Society of Australia website for details of geological heritage reports, and a bibliography.

Location:100540. Three kilometres north-east of the “Eastern Downs” property.

Narrow lunette ridge, (dotted), on the eastern end of lake near "Eastern Downs"

Access:
Seaspray Road.

Ownership:
Private land.

Geology/Geomorphology:
This large inter-dune lake is aligned east-west between hummocky sand ridges. The shorelines have been modified by erosion and spit growth. The eastern shoreline has been shaped into a broad, arcuate form by the action of prevailing westerly winds and in bounded by a low, irregular ridge. This ridge is composed of peat, fine sand and silt which has been blown from the lake floor during dry periods.

Significance:
State. This is one of the largest inter-dune lakes that lie on the coastal terraces in the study area. It has a much higher percentage of open water area than comparible wetlands, e.g. Kangaroo Swamp and Long Swamp. It represents an active example of the relict lake and ridge terrain near Gelliondale.

Management:
Discharge of waste materials into the lake should be prohibited as management strategies should aim to avoid deterioration in the water quality. The lake should not be drained or reclaimed in any way.
