Southeast Region


SouthEast region water levels hydrograph

*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.

*Drought zone 1 is the LTA in Southeast region.

Rainfall in our Southeast region was above average in April at 132% of the Long Term Average (LTA). Over the last three months (February to April inclusive), our Southeast region has received above average rainfall (184% of the LTA) and effective precipitation (227% 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 declined slightly but remain above average due to the above average rainfall over the autumn and winter period. Groundwater levels are likely to remain above average over the next six months if rainfall is more than 60% of the LTA. Groundwater levels in our southeast region are similar to during the wet winter experienced in 2013/14 and 2020/21.

Please refer to our Drought Plan for what this means for us and our customers.
