Notes

AHD G2 1.69 @ 13:17     G6  1.67  @ 13:05

Strong outflow down channel with pale discharge visible slightly to east.

Rough sea = SW swell impacting E end of beach, large amount of backwash occurring at mid beach & longshore drift across entrance over outflow, small waves are going up channel into the estuary. Small areas of east side of channel are sheer sided ( above lower exposed area).  These sides are currently sliding down into water as wave action in channel increases. Channel sides about .10 - .20 m.high & about .20m deep. About 8m wide

Wind much stronger gusts from south down channel

Water at side of GOR & OCR but across OOR at flood markers. Only at side of OOR closer to GOR
