Notes

No flow , mouth barred but some waves over berm at last hi tide

Berm increased in height

Attempted illegal opening last night(?) but currently no out flow as waves have been over this area on a wide front infilling the dug out drain

Beach horseshoe shaped, south west waves have strongly impacted mid beach with longshore drift travelling back to mouth. Sand is building up higher at both ends of beach

Last 2 day about 40c.temp but strong se wind today has created turbulence & estuary surprisingly clear of algae, small fish noted along s side

Water up to car park along low track but top track only damp

Many Squid carapaces, dead moths & small blue jellyfish along swash line

Dead Albatross found near mouth oxer past week

Silver gulls (7) feeding along swash line
