Notes
AHD G6 0.95 @ 09:15 AHD board difficult to read because of silt.
Observations made at low tide. Extremely pale discharge out around mouth over large sand build up - also sand building up in channel. Reduced flow only passing through very narrow gap between 1st & 2nd rock and a larger area over rapids between 2nd. & 3rd rock. Some water passing between 3rd. rock & cliff base
Sand on south side of estuary extending north into estuary. North wind driven waves (gusts much stronger than 4 ) have cut sheer side to the projection. Sand bar also exposed. The east side of the channel south of rocks also has sheer side -possibly resulting from tidal action
