For this Act, waterway means—

a river, creek, stream or other natural channel in which water flows (whether continuously or intermittently); or

the stormwater system or any other channel formed (whether completely or partly) by altering or relocating a waterway mentioned in paragraph (a); or

a lake, pond, lagoon or marsh (whether formed by geomorphic processes or by works) in which water collects (whether continuously or intermittently).

Waterway includes—

the bed that the water in the waterway normally flows over or is covered by; and

the banks that the water in the waterway normally flows between or is contained by.

However, waterway does not include land normally not part of the waterway that may be covered from time to time by floodwaters from the waterway.

In this section:

stormwater means water run-off that is normally collected by a stormwater system.

stormwater system means a system of pipes, gutters, drains and channels that are public works constructed to collect or transport stormwater in or through an urban area.
