Notes

Dark discharge out along foreshore

Strong outflow but small waves entering & travelling north across the sandbar

Sea rough with occasional very high set of waves -SW swell continues to impact east end of beach causing long-shore drift to mouth. Previously high sand near east end has been reduced in height by wave action. Swash-line high up on beach (many purple shells)

Recent storm surges have deposited more sand into the estuary extending sand at south side further north into the estuary(observation taken near low tide).Sand bar visable with channel partly cut into middle. The deep scour areas along low track have been filled in and new ones created. Areas of black sand at start of channel from estuary

Maram grass regeneration along base of dunes closer to mouth. Increase of Euphorbia paralais & senecio elegans along dunes

Thousands of small eels(?)/ fish making their way upstream observed at G4. moving along vev at side of channel away from strong flow

Rivernook flats have no visable water cover but all areas up stream to G6 are under water- no flood water below G4
