Notes

AHD @ G6 3.40 @12:10

Estuary from G4 to G6 has been mainly been affected by tidal movement for many weeks despite deep extensive flooding upstream in all areas Area downstream G4 has not been flooded nor water over OOR despite heavy rain fall & large amount of runoff

Dark discharge out along shore line to east but held back by rough sea. Waves entering very wide across the entrance, some travelling up the channel into the estuary where they are dispersed by strong north wind against sand projection & beach on south side of estuary. Large waves are being driven across the estuary by wind

Area directly below Gp1 site has been scoured out by wind & waves becoming much lower than the rest of the beach. More sand has been deposited on new areas of the dunes
