Notes

Mouth still barred, some waves have been over topping along the berm but not reaching the estuary where water levels are higher with wider front . Water is completely across from cliff to dunes at northern end of channel

No water over OCR & only puddles from rising ground water in camp ground ( no visible connection with river observed) Water still only at S side of OOR -between Lawson's & GOR (1 small puddle) More water near flood markers where a huge no. very small fish were observed swimming in drain & pond on S side. Small area of water on N side of road at west blocked culvert. More flood water on flats D/S G4

This is an very unusual event as there has been very little local rainfall /runoff. Water in estuary has been mainly from springs flowing strongly (confirmed by many local land owners) & only a very minimal flow from upstream catchment
