Notes
Observations made at low tide. Flowing strongly out through start of channel about 6m. wide then widening around rocks & going wide over sand build up at actual entrance. Strong flow creating large waves , Sheer sides of channel collapsing into flow & a very large amount of sand being carried. Water cascading over top of rocks then creating large deep furrows where it is met by some incoming waves from WSW swell & strong longshore drift. Outflow waves up to .70 m close to shoreline area where action is scouring out large amount of sand.
Later in the day there was a pale discharge around mouth then going south about 30-50 m out to sea. Sand turbidity visible
