Early Warning Network

Water NSW has an automated notification system, the Early Warning Network (EWN), to improve notification of dam and supply activities to the public. When you register, you nominate the dam(s) you are interested in and the type of notifications required. Once registered, you will receive notifications in the event of a significant dam release or an emergency situation depending on which you choose.

How to register

Important note about registering

  • Register as many contact details as possible so we have multiple ways to alert you in an emergency.
  • iWAS users are not automatically enrolled to the EWN. Please follow the directions above to be notified by EWN.
  • Please be aware that if you register a landline number, you will be called on that number by the system, whatever the time the alert is issued.

Notifications

Notifications list

What is a notification?

  • Factual information about our dams or water supply.
  • We may include possible effects (such as low level flooding or a need to move stock or equipment)
  • We may include specific location impacts if they have been agreed in advance with agencies.
  • Each dam's notifications will vary, depending on a number of factors, (such as gated or un-gated, conditions that lead to an alert and so forth).
  • There is a web page for each dam or service, showing what sort of notifications we will be sending for that dam or service.
  • Any inclusion of this information into forecasting or warnings will be done by agencies (Bureau of Meteorology, SES, councils etc).

Notification categories

  • Dam safety notifications
  • Flood notifications
  • High regulated releases
  • Fish River Supply Interruptions

How do I receive notifications?

You will receive notifications in all registered formats for any dam you have registered for. The service does not restrict notifications to your registered address, improving our ability to notify you.

  • Mobile phone (SMS message - max 158 characters)
  • Landline (Text to Voice) - This message will repeat the key message and should be fairly detailed.
  • Email - This message will be the most detailed and have links to other agencies who can provide more information, such as SES and Bureau of Meteorology.

What do I use my password for?

Use your password along with your email address to log in (at www.ewn.com.au) and update your details, change what you are registered for, or how you get notified (sms, email, landline).

How do I change or update my details?

  • If you registered by email - use your password along with your email address to log (at www.ewn.com.au) in and update your details, change what you are registered for, or how you get notified (sms, email, landline).
  • If you registered without email - contact 1300 662 077 to change what you are registered for, or how you get notified (sms, landline), you will receive a call verifying your identifty.
