    Notes "There were very few birds visible on the main waterbody or flying about. A few were on the southern side of Australia Island. We found the Cape Dwarf Chameleon in the reeds where we have found possibly the same one last year. The Water Thick knees were missing this count at the scout base, a possible explanation there was plenty of activity in the area during the school holidays. The schools started the new year this last week, so hopefully they will return. There were a few recreational users on the water in various craft. We found a dead fish (spotted grunter) on the shore near the Yacht Club basin, it had an oily substance coming from its insides (see the photo). It could have been a victim of the sewerage pollution washing in from the Keysers River. We established the estuary mouth was open as it is New Moon today. The water flowing out under Thesens pedestrian bridge was the same as measured at the railway bridge 1 metre per 6 seconds, which is considered fast. There were large sand bars evident with very little water in shallow and narrow channels at the ""Cookie Cutter"" between the 1st and 2nd bends from the estuary mouth. There was also a large sand bar at the Royal Road bridge. This is where the biggest concentration of birds were recorded for the lower section. The bulldozer was on the beach at the estuary mouth as part of the estuary mouth management process. A house owner opposite the vlei has had a pink spoonbill painted on the front wall and house face, which makes a striking mural with a bird theme. Note: No ZVNR staff were available to help with the count. The southern Marina canals, the Caravan Park and Park Island were not counted."
