Date and Time Friday 19th April 2019 11:40am
Approved Approved

Notes

Very pale discharge out (mainly salt water return).                                   Outflow very shallow around rocks & entrance. It is wider but also shallow at start of channel from estuary, the previous high sheer east side of channel has been reduced but sand is a lot higher around rocks. Some waves entering & continuing upstream.

Beach rises & falls with deep depressions (N -S direction) -2 bays have formed with a projection out to sea at mid beach. Area at east end has had full impact of previous WSW swell & rough seas extending well back towards dunes. Low water level has exposed large areas of sand on beach but sand bar in estuary is under water.

Many very small fish observed in shallow water beside low track.
