Stuarts Point groundwater update #11
Published on 26 April 2022
Key updates
Groundwater levels are falling very slowly with a drop of 0.5m since the end of March. Further rainfall will continue to impact the rate levels will fall and it is expected that groundwater will drop at a similar rate to last year.
Pumping is still taking place in low-lying residential areas and is likely to continue for several weeks.
As levels continue to drop, Fire and Rescue NSW have been disinfecting properties in residential areas.
Pumping to provide capacity in onsite septic systems also continues in low-lying residential areas where groundwater levels are impacting system operation.
Please do not drive, ride, walk or play surface water as it may pose a health risk.
The potential of heavy rainfall remains a concern as it risks further flooding of low lying properties.
If you need emergency help with flooding in your property call the NSW State Emergency Service on 13 25 00.
In life-threatening situations call triple zero (000) immediately.

How to read this diagram
The diagram shows the groundwater level for the past 30 days. The three graphs essentially present the same data but each with relation to a different reference point (or datum).
- The blue graph shows the depth of water below the Mount Point, which is where the laser that takes the reading is mounted.
- The red graph shows the height of the water above the Australian Height Datum (AHD) which is the official height metric based on the average of sea levels from 1966-68.
- The green graph shows the depth of the water below ground level at the location of the meter.
