Notes

AHD @ G6  1.93 @ 09:32

Dark discharge out along foreshore & continuing to east. Waves from last hi tide have been well up on beach where more sand has built up at mid beach with wide depression between there & east end. More sand has also built up along east side of entrance. Because of low water levels large areas of sand have become exposed in lagoon & inlet pipe on auto monitor at G2 is well above water level. Waves from longshore drift across entrance are crossing over outflow & combining with WSW/SW swell resulting in very small waves entering channel around rocks.

Erosion continues on S & SE face of Pt Ronald. Large build up of algae or duck weed? at west side of northern wetlands below township.
