SES BULLETIN – Major flooding at Mungindi Thursday, March 10
Major flooding has been observed upstream along the Weir River at Talwood and Jericho. Minor flooding has also been observed recently along the Macintyre River at Goondiwindi.
These flood waters are causing major flooding along the Barwon River at Mungindi, with a peak around the current level likely at Mungindi on Thursday.
These river levels are similar to those experienced in the April 2021 flood event, however, the river is expected to remain well below the December 2021 major flood levels.
Minor flooding is expected at Mogil Mogil later this week and is likely to extend to Collarenebri and Walgett during next week.
Further rises are possible and predictions for downstream locations will be refined as upstream peaks are observed.

What you need to do:
- Prepare now to minimise damage to your property and possessions.
- Consider evacuation as an option if severe flooding is predicted. Deciding to remain in your home when it is inundated or surrounded by floodwater can be dangerous.
- Ensure you can leave the area safely if flooding worsens.
- Stay up to date with information. Listen to flood warnings and follow advice on how to protect yourself, family, and property.
- People working or camping along the Barwon River should relocate to higher ground.
- Farmers and landholders are advised to relocate livestock, pumps, chemicals and equipment to higher ground. Do not wait until the flood peak approaches.
- Be aware of vermin, snakes and spiders seeking refuge from flood waters.
- If you become trapped by rising floodwater, seek refuge in the highest part of a sturdy building. Stay there and call triple zero (000) if you need rescue.
- Never drive, walk or play in floodwaters. Floodwater may be deep, fast flowing and may contain hidden snags and debris.
For emergency help in floods and storms, call the NSW State Emergency Service on 132 500.
In life threatening situations call triple zero (000) immediately.
