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:	130495 and coastline between 113467 and 158515. One to seven kilometres south-west of Seaspray.	Merriman Creek delta, truncated segments, Lake Denison.
Access:	Private road off Seaspray – Giffard Road.
Ownership:	Mainly private land around the lake.
Geology/Geomorphology:	Lake Denison is a brackish lagoon fringed by salt marsh and lies between a low, well defined bluff and the outer barrier sand ridges. Adjacent to the lake are several lagoons which represent inlets to the lake now blocked by sand. Truncated segments similar to those described near Woodside Beach occur between Lake Denison and Seaspray.
Significance:	Regional. The lake, barrier, bluff and the lagoonal channels represent distinctive stages in the evolution of barrier and lagoon systems. Of interest here also is the history of marram grass (Ammophila arenaria) plantings and the record of the breachings of the outer barrier by storm waves. Neither of these topics has been completely documented.
Management:	Reclamation and drainage of the salt marsh zone would gradually obscure the old lagoonal channels but high residual soil salinity will probably limit intensive utilisation of the lagoonal flats. Hence, localised land disturbance for further agricultural uses is unlikely to seriously alter the configuration of the significant features.
