Date and Time	Friday 19th February 2010 07:45am
Approved	Approved

Notes

1.Out flow has increased creating a larger pool upstream of the rocks with 60cm banks on east side. The water in this pool is higher than downstream of rocks. Water is cascading over rocks in channel between large rocks and cliff (4-5m wide)
2. water downstream of rocks is sweeping strongly around the curve(east side) then through a deeper channel (close to cliff) across the sand build up at the mouth. The flow is very turbulent. Longshore drift is still bringing sand back into channel and the high edge (50cm +) constantly dropping into the flow.
3.The redish brown discharge is mainly around the mouth and slightly to east. A lot of sand is visiable in the breakers south of the entrance
4. Beach front has a more gradual slope to ocean and rocks at east end are exposed
5.Water level in estuary is higher
