The BOM seasonal climate outlooks and streamflow forecasts for the summer period (2019-20) across North East Victoria show below average rainfall conditions and warmer than average temperatures with low streamflow. Based on the BOM outlooks and other available data, we forecast dry climate conditions for all water supply systems.
Although water restrictions are not expected for the majority of our towns this summer, they may be needed in 2020-21 if the dry conditions continue.
At this time there are no ‘Stage Restrictions’ implemented on any town within our service region. However, all of Victoria has 'Permanent Water Saving Rules' in place. These rules are a set of compulsory common-sense measures to reduce demand and make sure we use water efficiently.
You can view the rules here.
The Department of Environment, Land, Water and Planning controls the rules surrounding each stage of water restrictions which are applicable to all Victorian urban water corporations.
North East Water generally determines when water restrictions will be implemented in each town except in certain circumstances when we are directed by the Minister for Water.
We monitor water usage, storage levels and river flows which are then combined with river flow, rainfall and temperature outlooks from the Bureau of Meteorology. This allows us to forecast if towns and cities in our region need to be placed on water restrictions.
Conditions are continually monitored and our ‘Water Outlooks’ for each are issued on 1 December and then updated regularly over summer.
Restrictions have the most benefit when they’re absolutely necessary as there is a risk that customers will get ‘fatigued’ about such measures before they are really needed. We are currently monitoring conditions in accordance with our Drought Preparedness Plan and will implement restrictions if required. Water restrictions are not currently required.
We remind customers that being water wise is similar to bushfire preparedness. You shouldn’t start thinking about a fire plan when a fire is at your doorstep and you shouldn’t wait until a drought before saving water.
Lake Hume is currently at 21% capacity. This level is lower than usual for this time of year and reflects the dry conditions that we have had. The Murray Darling Basin Authority will manage Lake Hume to maximise volumes in storage via natural inflows from the Murray and Mitta Mitta rivers. In addition, water transfers from Dartmouth to Hume will continue to supplement natural inflows to Lake Hume.
Dartmouth Dam serves as a drought reserve and is currently at 50% of capacity and transferring water to Lake Hume.
The River Murray system operated by the Murray-Darling Basin Authority, consists of many storages and lochs to ensure that water can be stored and delivered to water holders across three states. Water is used for irrigation, environmental and urban water supplies. Urban water use makes up approximately 7% of all water use across the Murray System.
North East Water holds approximately 1% of water available on the Murray system which is used to supply half of our customer base. Our other customers receive their water from local waterways, storages and groundwater.
The Murray system operates on a seasonal water allocation model. The season runs from 1 July to 30 June each year. The Northern Victorian Resource Manager (NVRM) determines how much allocation is available. The level of allocation is based on how much water is available in the whole Victorian Murray system.
North East Water holds water entitlement that is far greater than annual customer demand. We hold this extra water to ensure that we can meet demand during dry years when reduced allocation is made available by the NVRM. We also have access to 'carryover’ – this is unused water allocation that can be carried over into the following season. Carryover into 2019-20 was maximised in preparation for ongoing dry conditions. This means that North East Water has access to allocated entitlement plus allocation carried over from the previous season.
Albury City Council is the responsible authority that supplies Albury with treated drinking water. Albury City determines when to implement restrictions based on conditions, outlooks and allocations. Although water is accessed from the Murray system on both sides of the border, the rules that determine how much water can be used by North East Water and Albury City are different. The Murray Darling Basin Authority determines how much water can be shared with Victoria and NSW.
North East Water holds a volume of water entitlement for the Murray system that provides the right to extract water. In Victoria, the amount of water available from this entitlement, or allocation, is set progressively by the Northern Victoria Resource Manager at regular intervals throughout the year. The percentage of allocation available to North East Water is the same as for irrigation water users and reflects how much water the state of Victoria currently has access to in the Murray system. In NSW, the allocation for town water supplies on the Murray system is determined for the year by the NSW government on 1 July. This allocation can be different to the allocation issued for irrigation water users.
The last time restrictions were needed in north-east Victoria was in 2010. Over the past decade we have invested around $35 million in projects to improve the drought resilience of our region. Projects include new efficient water treatment plants in Bright, Myrtleford, Whitfield and Eskdale as well as several new water pipe networks linking smaller towns to larger centres.
We also have a Drought Preparedness Plan that highlights our response for when a shortfall in water availability occurs. The Plan is tailored to each individual water supply system with trigger levels clearly indicating what actions are required and when. It is reviewed every five years or upon any supply system change. You can access the DPP here for more information.
For most towns across our service region, the more water people can save in the coming months, means more water will be available in the following year, reducing the likelihood of restrictions.

Permanent Water Saving Rules are also in place across Victoria. The compulsory rules include using a trigger nozzle on your hose to water the garden or wash the car, only using watering systems between 6pm and 10am, and never hosing concrete paths or driveways.
