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 above average in February at 225% of the Long Term Average (LTA). Over the last three months (December to February), our East region has received above average rainfall (146% of the LTA). As a result, soils remain wetter than average, meaning any forthcoming rainfall will provide a greater contribution to groundwater recharge.
Groundwater levels have continued to increase in February at a faster rate than the LTA curve as a result of above average rainfall over the last three months. Groundwater levels are likely to remain above average over the next seven months if rainfall is more than 60% of the LTA. Groundwater levels are currently higher than during the wet winters of 2013/14 and 2020/21 at this point in time.
Please refer to our Drought Plan for what this means for us and our customers.
