    Notes "What a turnout we had today! Many newcomers from the Marina and Lakeside areas. They have formed a WhatsApp birding group. Kyran the Reserve manager was able to give the group a short introduction to the Reserve before the group set off. He and his students were doing the Marina canals in canoes to day. It is the first time in about 3 1/2 years that the southern canal is being counted. The weather was ideal, with high clouds from the SE. There was no wind at ground level, the sun was up and the water surface was like a mirror. The air temparature was cold at sunrise and warmed up considerably requiring layers of clothing to be taken off. Zandvlei has had a number of sewerage spills flowing into the main waterbody and in the canals of the Marina this year. The salinity levels have been kept high this year with the estuary mouth management. The winter mouth opening was eariler this year due to a large sewerage inflow, and allowing the flush to take place as best practice. The estuary mouth stays open until September New Moon or Full Moon depending when in the month these occur. The pond weed has not recovered yet so Coot are not as prolific as in past counts. It was a very good count with 34 species listed. "
