What is a catchment?

A catchment is an area with a natural boundary (typically formed by ridges, hills or mountains) within which all surface water drains from higher areas to a common creek or river channel at the bottom.

Larger catchments are made up of smaller areas called sub-catchments. Saltwater Creek Catchment is a sub-catchment of the larger Cairns Urban Catchment.
