Observation details


Estuary Gellibrand River Estuary
Site Gellibrand River Estuary Mouth Observation Site
Observation ID #13274
Date and Time Friday 23rd August 2019 16:20pm
Approved Pending


Reduced dark discharge out alongside foreshore extending far to the east.   High seas earlier this week have created a high beach area at mid beach & increased sand build up at entrance. The east end of the beach has been scoured out & is lower than previously. Waves from rough sea are impacting on beach creating strong longshore drift that goes over the outflow creating small waves that travel up channel into lagoon

Flood water  is draining but levels remain high upstream G4
