Notes

Mouth Barred                  AHD G6   1.14 @ 08:45     G2 1.17 @ 09:05

Observations taken near very low tide - Large expanse of beach with sand highest at east end possibly highest it has been for about 10-15 years.( However sand has been removed from Rivernook beach east of this site.) The shore line is horseshoe shaped with deep backwash scouring mid beach. Sand was visible in breakers going out to sea from this area

Berm is more exposed - front now1.70m high with more sand build up in that area. More sand has covered the rocks in the channel & the front of the estuary has widened. The water is also completely across to the dunes at the start of the channel

Water has completely covered the low track but there is no water over any other tracks or roads. Very large number of small fish observed at side of estuary from G2 site to start of channel. . Water is on flats downstream G4 but not on any pasture upstream - some in drains in small area close to G4
