This definition applies to:

The volume of water that a water storage can hold between the minimum supply level and full supply level; equal to the total storage capacity excluding the dead storage capacity. It is the sum of this capacity that is reported for a collection of water storages. See the water storage diagram for more information.

Synonym: accessible storage capacity

This definition applies to:

This definition applies to:

An artificial or constructed waterway designed to convey water. Often described as open channels to distinguish then from pipes, channels can be categorised as: main (or major) channels whose primary purpose is to convey bulk water from headworks storage or river diversion points into the distribution system; or distribution channels whose primary purpose is to deliver water from main channels to individual farms. The term canal may sometimes be used for main channels that are used for other purposes than just conveyance of bulk water, such as recreation or transport.
