    Notes Weather - clear sky, sunny, light SE breeze. The preceding days of the week, the wind had been very strong SE. Most of the birds were sheltering out of the wind. The mouth of the estuary was closed, with evidence of the spring tide washing kelp over the berm into the estuary mouth under the promenade walkway. Barry and Val Cleveland counted by canoe and did the northern canals of the Marina and the Night Heron roost canals. The pans in the upper Reserve area are dry. There was no inflow into Zandvlei from under the railway bridge confluence of the Westlake and Keysers Rivers.
