How do catchments work?
Within a catchment, water runs by gravity to the lowest point. The water is called surface runoff if it stays on the top of the land or groundwater flow if it soaks into the ground. When water reaches the lowest point in a catchment, it eventually flows into a creek, river, lake, lagoon, wetland or the ocean.
How are catchments managed?

What is catchment hydrological cycle?
a catchment is an area of land in which water flowing across the land surface drains into a particular stream or river and ultimately flows through a single point or outlet on that stream or river (Fig 1.5)
What is catchment outlet?
A catchment is often bordered by hills or mountains. The water enters via precipitation (rain or snow) and then moves across the surface or subsurface (as groundwater) until it drains into a stream or river. The outlet may be another stream or river, wetland, lake, estuary or the ocean.

A catchment is an area of land, usually bounded by mountains, over which water flows and is collected by the natural landscape. In a catchment, all rain and run-off water eventually flows into a creek, river, lake, lagoon or the ocean.
What are the threats to our local catchment?
Pollutants on the move Heavy rain and flooding in the catchment can transport pollutants over the land and into creeks and rivers. Creeks and rivers can then carry potential pollutants into our drinking water storages. Heavy rain can cause overflows of sewage and industrial waste.
What is the boundary between catchments?
A catchment is the land area from which all run-off water flows to form a waterway. Its boundary is the natural features, such as hills and mountains, which surround it, forming what is known as the watershed. A watershed is simply the dividing ridge between two catchments with water flowing down each side.

How are catchment stories compiled by the Department of Environment?
The information in the ‘catchment stories’ was compiled with experts using the ‘walking the landscape’ process, where experts systematically worked through a catchment in a facilitated workshop, to incorporate diverse knowledge on the landscape.
