Annotation
At Hermits Haven, near Hepburn Point at Coles Bay, permanent groundwater probably exists only in small isolated pockets of dune sand behind the beaches. Elsewhere on the 13 ha property, the superficial sand, clay and gravel deposits overlying basement granite are irregular in thickness and variable in lithology. Even after heavy rain, they contain only temporary perched water tables. To provide water for a proposed holiday development, the creek along the western boundary of the property should be dammed.
