Catchment Hydrology
The Centennial Parklands ponds system is a modified remnant of the originally much more extensive freshwater wetlands at the head of the Botany Bay catchment.
Land filling and urban development in the late 19th century has reduced the extent of these wetlands.
The area still functions as a catchment area with stormwater and surface runoff diverted from surrounding suburbs collecting in the Parklands and the vast and shallow groundwater table underlying the Parklands, before continuing downstream to the Botany Wetlands and Botany Bay.
