Notes

AHD G6 1.28 @ 11:45 = both G6 & G2 are the same

Mouth barred- the actual length of the berm without water is not great but only a very narrow very shallow projection is coming out of the estuary where an extensive sand build up is visible extending well into the estuary almost up to the tunnel entrance. Height of berm from estuary is .10 with gradual slope down to ocean. the recent storm has considerably lowered the beach around entrance & up to the sand spit at mid beach

No water over any roads but flats DS G4 have water cover.
