Gnangara Water Mound
Whiteman Park was established in order to protect the southern tip of the Gnangara Water Mound, a large underground water source that supplies drinking water for up to 60% of Perth.
The Gnangara Mound is Perth’s largest source of groundwater, stretching from Gingin in the north, to the Swan River in the south.
Wetland and groundwater levels on the Gnangara Mound have been under considerable pressure in recent years due to a combination of the drying climate (less rainfall) limiting recharge of the mound, and extraction for irrigation and public water supply purposes.
