Allocation

1.Water that is actually available to use or trade in any given year, including new allocations and carryover.

2. The water that is actually in the dam in any given year is allocated against water shares. The seasonal allocation is the percentage of your water share volume available under current resource conditions, as determined by the resource manager.

For example, in a dry year a 50% allocation to your 100 ML water share gives you 50 ML of water available to use or trade. A 100% allocation means that you have your full water share volume available.

In northern Victoria  the resource manager uses seasonal determination instead of allocation when allocating water to entitlements.  Seasonal determination is the term used in bulk entitlements and Victoria’s Water Act 1989.

Declared water system

A water system that has been declared in accordance with section 6A of the Water Act 1989.

In these water systems, the old water rights and take and use licences have been converted into unbundled entitlements.

As of 2012, the declared water systems are:
Broken, Bullarook, Campaspe,Goulburn, Loddon, Murray and Ovens which were all declared in July 2007 and the Werribee and Thomson/Macalister declared in July 2008.

A detailed description of these regulated water systems is in the declaration documents on the water reform history page

Entitlement

A right to take/use/extract/have water delivered that may be limited by conditions.

Different entitlements are necessary depending on where and how water is taken, and what it is then used for.

The most common types of entitlements are water shares, delivery shares, water-use licences, take and use licences, water allowances, supplies by agreement and works licences.

Groundwater Management Areas (GMAs)

A Groundwater Management Area (GMA) is an area where groundwater has been intensively developed or has the potential to be. GMAs have boundaries defined for the purposes of setting a PCV for ongoing management

Groundwater Management Units (GMUs)

Groundwater Management Units (GMU) define areas where specific rules are used to manage the resource according to the needs of groundwater users and the environment. There are two types of Groundwater Management Units: Water Supply Protection Areas (WSPAs), and Groundwater Management Areas. (GMAs)

Low risk of spill declaration

An announcement made by the resource manager for northern Victoria that there is a low risk of a spill occurring from dams.

The resource manager looks at volumes in the dams, likely inflows and expected releases.
If the risk of the dams spilling later in the season is more than 10 per cent, a declaration is not made.

A low-risk-of-spill declaration is made as soon as the risk is less than 10 per cent.

The low risk of spill declaration makes carryover water in a spillable water account available for use or trade.

This is different from a spill  announcement.

Regulated water system

A water system where the flow of the river is regulated through the operation of major storages or weirs to secure water supplies.

For example, in northern Victoria there are seven regulated water systems: the Murray, Ovens, Broken, Goulburn, Campaspe, Loddon and Bullarook.

In southern Victoria the regulated systems are the Thomson/Macalister and Werribee.

Resource Manager

The Minister for Water appoints a resource manager to allocate water on regulated river systems in accordance with Victorian water sharing rules.

A resource manager makes seasonal determinations for regulated water systems based on water availability and water sharing rules.

The resource manager is usually the water corporation responsible for that area.

Seasonal determination

The percentage of water share volume available under current resource conditions determined by the resource manager for northern Victorian regulated river systems.

Since 1 July 2012 the resource manager has used seasonal determination instead of the previously used term, seasonal allocation. This is to distinguish between water available under current resource conditions and the water customers have available because of carryover

Seasonal outlook

When the resource manager for northern Victoria looks ahead to the new irrigation season and estimates indications of allocation levels for each system based on a range of seasonal conditions and scenarios.

The resource manager uses the full record of inflows into storages to assess seasonal determinations for a range of scenarios.

These are categorised as:
wet - inflow volumes that have 10 chances in 100 (or 1 chance in 10) of being exceeded
average - inflow volumes that have 50 chances in 100 (or 5 chances in 10) of being exceeded, and
dry - inflow volumes that have 90 chances in 100 (or 9 chances in 10) of being exceeded.

The first outlook for a new irrigation season starting on 1 July is usually announced around February, and updated at various times through the season.

Spill

When water is discharged from the storage when there is more water in supply than demand for water.

Spill announcement

An announcement made by the resource manager that water is spilling from a dam, which has implications for the spillable water account.

This is different from a low risk of spill declaration.

In southern Victoria a spill declaration is an opportunity for irrigators to take water over and above their allocation annually (see spill entitlement).

State Observation Bore Network (SOBN)

Organisations charged with supplying water to people in towns, farmers and other water users across Victoria for urban, industrial and commercial use.

They administer the diversion of water from waterways and the extraction of groundwater.

The corporation must provide the service of delivering water to the owner or occupier of each serviced property in its irrigation district at the volumes and for the periods determined by the corporation.

Water Register

The Water Register is a public register that records water-related entitlements in Victoria.

It holds water shares recorded by the Water Registrar, together with mortgages and limited term transfers (leases) relevant to these water shares, records of licences to take and use surface water and groundwater, and records of works-related licences.

The register also holds records of water allocations available in the current season and tracks and reconciles volumes of water entitlements by water system and trading zone.

It generates statistics and reports on levels of use, directions of trade, and prices paid.

Water Registrar

Victoria's Water Registrar records transactions on water shares including transfers, mortgages, limited term transfers and discharges of mortgage.

The  Registrar is also responsible for the Water Register system and the accuracy, reliability and accessibility of records

Waterway

A river, creek, stream, watercourse and a natural channel where water regularly flows, whether or not the flow is continuous (as defined in the Water Act 1989).

Groundwater Management Units (GMUs)

Groundwater Management Units (GMU) define areas where specific rules are used to manage the resource according to the needs of groundwater users and the environment. There are two types of Groundwater Management Units: Water Supply Protection Areas (WSPAs), and Groundwater Management Areas. (GMAs)

Groundwater Management Areas (GMAs)

A Groundwater Management Area (GMA) is an area where groundwater has been intensively developed or has the potential to be. GMAs have boundaries defined for the purposes of setting a PCV for ongoing management

Water Supply Protection Areas (WSPAs)

A Water Supply Protection Area is an area declared under the Water Act 1989 to protect the groundwater or surface water resources through the development of a statutory management plan.
