Notes
Very strong dark discharge out around mouth & to east, increased flow caused by very low tide 0.17 @ 06:31 - large amount of foam over exposed rocks & beach at east end of beach. Despite strong outflow waves are entering & travelling down sheer east side of a 25-30m. wide channel (.50-1.00m high) which is collapsing into the flow. At the start of the lagoon waves turn sharply east travelling over the increased sand build up resulting from recent very rough seas. Waves in all directions at entrance & large amount of sand moving in the flow along the channel. Area directly around mouth has been lowered & more of the old breakwater post has been exposed
