Notes

AHD G6 1.17  @ 14:40

Mouth closed & short berm formed area between sea & estuary.The length has been reduced because of recent heavy local rainfall raising water level (over 40m. in some areas) . Waves over topping berm but not reaching estuary (however this had occurred during last hi tide). Entrance very dynamic & waves being driven  far up on beach driven by strong SW swell.

More sand over rocks, only about .30 of 2nd rock remains exposed. Large amount of sand visible in breakers all along beach. More rocks down at south face of Pt Ronald

No flood water over any roads or tracks (apart from low track) nor in camp ground

Many small fish observed in shallows along low track & around auto monitor
