Notes

Out flow reducing, only running along side high sheer beach face for a short distance then out south.Sand bar at mouth has increased also sand from east forcing flow between these areas. Waves from SE swell are crossing the sand bar & small waves trying to go upstream. The 2nd rock is just starting to appear.

Sand bar in estuary is exposed & sand on S side of estuary extends far out . The high water has dropped significantly but the algal 'nets' that usually blanket the submerged stream side veg. are not evident, (but 2 very small contained pools along the low track do have these nets.) Some dead flathead gudgeons in these areas

Throughout this event there have been thousands of millipedes in all areas -even the dunes at Gp1
