Sea grass exposed (about 8m) on east side of estuary 2.Reducing dark brown discharge around mouth & to west. Some to about 50m. east 3.New sand projection starting near mouth (about 30m. from rocks) 4.Small area near rocks at east end of beach has been scoured out . The sand projection of the last few weeks remains about 50m west and is increasing along the beach to new area.(Horseshoe shape flattening out) 5.Visiability reduced because of sea fog. & 7ml. rain at G6 (30.10.09) 6.Senecio elegans is now flowering around the Ocean beach car park and along the western cliff(as well as everywhere else along the dunes) GP.1 GP.2 GP.3 GP.4 GP.5
