Recent Events
Event Details |

29-03-2017 Estuary Entrance Closure The Powlett Estuary Mouth closed on this date. The closure was likely to have occurred in the early hours of the morning. |
14-06-2016 Estuary Entrance Opening Estuary mouth artificially opened at 2.63m AHD, with peak flow of 663.74 mega litres per day on the 12th of June at Foster Creek Junction gauge. |
02-06-2016 Estuary Entrance Closure The Powlett is still closed, with the water level sitting at 2.34m AHD. At this height the gravel section of the Mouth of Powlett Road is only mildly inundated (see image attached). This is different to previous years, where at this height this section of road would have been completely inundated. This is thanks to the Bass Coast Shire Council who lifted this section of road following the 2015 estuary closure event. |
14-05-2016 Estuary Entrance Closure The estuary opening conducted on the 13th of May was unsuccessful. The opening began early in the day and works continued into the night. With a lack of water level height @ 2.01m AHD, and river flows (100mg/l per day), the large seas (2 to 3 metres) and large high tides (1.6 to 1.7m) there just wasn't enough water in the estuary to prevent the ocean from reclosing the mouth. |
13-05-2016 Estuary Entrance Opening Powlett Estuary Artificially opened at 2.01m AHD, with a flow of 90 to 100mg/l per day, a 2 to 3 metre ocean swell and a 1.6 to 1.7m high tide. |
