Notes

AHD @ G6 2.41@09:00

Dark discharge around mouth being held back by V.rough SW Swell

SW swell impacting on E end of beach has created a continuous sand cliff from mid beach to rocks at east end (1-2m.) Some waves going over the top.

Very strong rip going out at east end, meeting incoming waves then travelling fast parallel to foreshore toward mouth(west). The resulting longshore drift on reaching the mouth turns N entering the channel and then turns east into the estuary

Waves in all direction at mouth with backwash rolling more sand into channel (back wash stirring up sand all along the beach)

Sand build up at mouth visible under water. Sand stir visible in ocean

Water has covered all of low track at last hi tide

Strong N wind across estuary

OOR water visible at edge of road near flood markers, water across causeway @ G4 & flats upstream underwater but level lower than 25/6/16

4 dead Kangaroos found NW end of camp ground
