Waterway — Catchment — Sub-catchment areas

***This dataset is available on Brisbane City Council’s open data website – data.brisbane.qld.gov.au. The site provides additional features for viewing and interacting with the data and for downloading the data in various formats.*** Waterway sub\-catchments are smaller divisions within a larger waterway catchment area, which represents a more specific area of land that contributes to the flow of water within Brisbane City Council's waterways.

Like catchments, a sub\-catchment is typically delineated based on the natural drainage patterns of the land, such as the flow of streams or rivers. It is defined by the topographic features and the boundaries of the land that drain into a specific tributary or section of the larger catchment.
