Notes

1. Dark discharge around mouth & slightly to east but main flow seems to be west infront of cliffs. The east flow seems to be stopped by the sand projection near east end of beach. This sand projection (beach) has increased but sea is much closer to dunes (beach) near mouth
2.Sand is building up into 'cliffs' on beach (1/3 from mouth)
3.Sand is visiable in waves out to sea up to70m.
Sand is also being deposited into channel by longshore drift
4.Low tide has exposed a very large area of sand bars.
Dead and rotting seagrass on eastern side of estuary is also exposed
5.Senecio elegans in full flower. Huge increase from last year. All through the dunes and along western cliff
