    Notes A cold NW wind was blowing strongly (30 - 35kmh), the sun was shining brightly, with heavy cloud on the peninsula mountain range. No rain present. The light condition was very good. The mouth of the estuary was open and the water was flowing strongly under the railway bridge into Zandvlei. The water level was low. On the western shoreline the waterline was a minimum of 60cm below the waterline high mark on the shoreline. Barry and Val Cleveland were in a canoe and checked the Night Heron roost in the northern canals. They also recorded the birds in the Marina canals from Uitsig Cove in the north down to Park Island Bridge. There was no waterweed present on the surface to support the Whitebacked Duck requirement on the western shores of Zandvlei.
