This information has been developed from the publication:

Sites of Geological and Geomorphological Significance in Central Gippsland (1981) by Neville Rosengren, M.S McRae-Williams and S.M Kraemers

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. Reference should be made to the most recent reports.

Location:	455181. Three kilometres south-west of Agnes Railway Station.	Sites 8120-8 9 10
Access:	Barry Road, private roads south of the South Gippsland Highway.
Ownership:	Crown Land along coast, private land.
Geology/Geomorphology:	The estuary of the Agnes River describes several very tight meanders that sweep across the entire width of the incised flood plain north of Barry Beach. The estuary is fringed by a dense stand of mangroves (Avicennia marina) and there are broad expanses of the tidal flats occupied by rice-grass (Spartina townsendii). The meander pattern of the channel continues across the sandy inter-tidal and sub-tidal sand flats south of the river mouth.
Significance:	Regional. This is one of the most rigorous growth areas of the introduced marsh grass Spartina. Studies of the physiographic effects of this growth are continuing.
Management:	Dredging or filling of the estuarine section should be prohibited.
