|16-08-2022 Weather Event
After heavy rains (60mm+) over the weekend in a saturated catchments cause peak flows of 8500ML/day at D/S Powlett/Foster Confluence. This reached the estuary yesterday and caused estuary water levels to peak at 2.44mAHD and the estuary to be flushed out with freshwater. Mouth of Powlett Rd was flooded. 1st photo taken from social media and was taken on August 17 after water levels began to subside.
|09-06-2022 Estuary Entrance Opening
With water levels reaching a maximum of 2.66mAHD and peak flows recorded at 1715ML/day later in the night at Powlett/Foster confluence (Wattlebank) the decision was made to artificially open the Powlett River Estuary. With a berm height of 2.9mAHD a natural opening had too many risks involved hence the need for an artificial opening. The opening was successful in lowering water levels and lowered water levels by over 1.5m.
