    Notes 18/10/2013 a very strong SE wind blew. The estuary mouth was closed in the late afternoon on same day. Full moon is today 19/10/2013. The water level was quite high with the mouth closed, compared to the last 4 months with the mouth open. There was no visible water flow under the railway bridge at the confluence of the Keysers and Westlake Rivers into Zandvlei. The sky was clear and sunny with a gentle SE breeze. There was the odd carp spawning with thrashing about. Observations by local residents indicate the carp all stopped spawning on 13/10/2013, after fierce activity for days preceeding this. In this process the water was very turbid and visiblity at the surface almost zero. Visiblity today was about 15cm down from the surface.
