Flood Warning Number: 38

MODERATE FLOODING POSSIBLE AT MUDALL ON TUESDAY

Rainfall across the Bogan catchment last week has caused renewed river rises and prolonged flooding.

An earlier flood peak along the Bogan River has passed Gongolgon, where flooding has eased. River levels may remain elevated near the minor flood level as floodwaters from last week's rainfall continue to extend downstream.

Flood Safety Advice:

In life threatening emergencies, call 000 (triple zero) immediately. If you require rescue, assistance to evacuate or other emergency help, ring NSW SES on 132 500.

  • * Avoid drowning. Stay out of rising water, seek refuge in the highest available place.
  • * Prevent damage to your vehicle. Move it under cover, away from areas likely to flood.
  • * Avoid being swept away. Stay out of fast-flowing creeks and storm drains.
  • * Never drive, ride or walk through flood water. Flood water can be deceptive and dangerous.
