Notes

Dark discharge out continuing along shoreline to east. Very rough wsw swell impacting on east end of beach where a large dense area of foam covers the beach & rocks. The very rough sea was sending small waves over the top of the strong outflow up the channel into the estuary

South side of estuary sand projection at start of channel is directing flow to create a small bay at the SE corner. Despite high flood water around G4 & upstream a small area of the sand bar was exposed
