section 3

1.5 year daily flow volume, for a node, means the daily flow, at the node, that has a 67% probability of being reached at least once a year.

90% non-zero daily flow, for a node, means the daily flow, at the node, that is equalled or exceeded on 90% of the days on which there is a flow under the pre-development flow pattern.

adopted middle thread distance means the distance in kilometres, measured along the middle of a watercourse, that a specific point in the watercourse is, at the commencement of this plan, from—

AMTD means the adopted middle thread distance.

annual variability, for a flow at a point in a watercourse, means the amount of change in the flow that happens between years.

annual volume probability, for a water allocation group, means the percentage of years in the simulation period in which the volume of water that may be taken by the group is at least the total of the nominal volumes for the allocations in the group.

annual volumetric limit, for a water allocation, means the maximum volume of water that may be taken under the allocation in a water year.

authorisation means a water licence, water permit, interim water allocation or other authority to take water given under the Act or the repealed Act, other than a water permit for stock or domestic purposes.

coordinated project means a coordinated project under the State Development and Public Works Organisation Act 1971.

daily flow, for a node, means the volume of water, expressed in megalitres, that flows past the node in a day.

daily volumetric limit, for a water entitlement, means the maximum volume of water that may be taken under the entitlement in a day.

discharge, for a flow at a point in a watercourse, means the rate at which water passes the point, measured in cubic metres per second or megalitres per day.

event duration, for a flow at a point in a watercourse, means the period of time when the discharge is greater than or less than the level necessary for a particular ecological process to happen.

existing groundwater works means—

flow regime means the entire range of flows at a point in a watercourse including variations in the watercourse height, discharge, seasonality, annual variability and event duration.

groundwater means underground water not connected to artesian water.

groundwater management area see section 7.

Indigenous purpose means the purpose of helping an Indigenous community achieve its economic and social aspirations.

in-stream works means works constructed within the banks of a watercourse.

IQQM computer program means the department’s Integrated Quantity and Quality Modelling computer program, and associated statistical analysis and reporting programs, that simulate daily stream flows, flow management, storages, releases, in-stream infrastructure, water diversions, water demands and other hydrologic events in the plan area.

mean annual flow, for a node, means the total volume of flow, at the node, in the simulation period divided by the number of years in the simulation period.

median annual flow, for a node, means the annual flow volume, at the node, that is equalled or exceeded in 50% of years in the simulation period.

micro hydro-electric power scheme means a scheme that—

node see section 9.

nominal entitlement see the Water Regulation 2016, section 28.

pre-development flow pattern means the pattern of water flows, during the simulation period, decided by the chief executive using the IQQM computer program as if—

prescribed existing groundwater works, for chapter 5, part 3, division 2, subdivision 3, see section 67.

prescribed groundwater management area, for chapter 5, part 3, division 2, subdivision 3, see section 67.

project of regional significance means a project the chief executive considers to be a project of regional significance under section 29.

refugia means the habitats required by a species during a time of stress, including, for example, drought.

resource operations plan means the resource operations plan to implement this plan.

Note—

See the Act, section 1266.

seasonality, for a flow in a watercourse, means the time of year when the flow happens.

simulated mean annual diversion, for an authorisation or group of authorisations, means the total volume of water simulated to have been taken under the authorisations, if the authorisations were in existence for the whole of the simulation period, divided by the number of years in the simulation period.

simulation period means the period from 1 January 1890 to 30 June 2008.

State purpose means—

subcatchment area see section 6.

supplemented water means water supplied under an interim resource operations licence, resource operations licence or other authority to operate water infrastructure.

surface water see section 10(1).

this plan see section 1.

traditional owners, in the plan area, means the Aboriginal people who identify as descendants of the original inhabitants of the area.

unsupplemented surface water means surface water that is unsupplemented water.

unallocated water means water available for allocation in the plan area.

unsupplemented water means water that is not supplemented water.

unsupplemented water allocation means a water allocation to take unsupplemented water.

waterhole means a part of a watercourse that contains water after the watercourse ceases to flow, other than a part of a watercourse that is within the storage area of a dam on the watercourse.
