East Region
*The long term average (LTA) has been calculated statistically, using the long term data record for this hydrograph. The respective drought zones are used as operational triggers, and have been derived using the LTA.
Rainfall in our East region was below average in July at 93% of the Long Term Average (LTA). Over the last three months (May to July inclusive), our East region has received below average rainfall (68% of the LTA) and well below average effective precipitation (44% of the LTA). Soils dryness (SMD) remains above average, meaning any forthcoming rainfall is unlikely to contribute to groundwater recharge.
Groundwater levels continued to decline through July and remain below average due to below average rainfall and effective precipitation in 2025 to date. The decline in levels through July has resulted in groundwater levels reaching our Environmental Stress trigger. Groundwater levels are likely to remain within this trigger over the summer and autumn if rainfall is less than average.
Please refer to our Drought Plan for what this means for us and our customers.
