EstuaryWatch Data Portal

On the 9th of July the sand berm was at approximately 2.21m AHD and the water levels were at 2.11m AHD (i.e. 10cm below height of sand berm). At 2.11m AHD the estuary was mostly made up of seawater from the weekends swells and tides. On the 10th of July, Freshwater Inflows further increased the water level height by to 2.21m AHD, which was enough to promote a natural opening early this morning (2am ish). Flows peaked at 455 ml / day on Sunday night / Monday morning and are currently at 125 ml / day. Surface waters were still quite salty during opening (i.e. 10,000 us/cm EC) resulting from the huge inputs of saltwater into the estuary over the weekend.
