To the northeast of the cottages are the remains of a propagating structure - further testifying to the importance attached to the establishment and maintenance of this landscape. Nearby is a very large Scribbly Gum which, as part of the indigenous vegetation, long predates any use of the site for Sydney's water supply. The loop road, giving access to the area along the ridge, is edged by a low stone retaining wall that also dates to the late 1920s-1930s period. Along the main entry road to the dam site near an old gate are clumps of Agave americana and Flax which may indicate the earlier presence of a cottage now demolished.
