    Notes The main body of the vlei was full due to the mouth being open for the spring high tide. Bright, sunny morning with light SE wind. No clouds. The start time is not ideal for summer time. There was no sago pond weed (potamogeton) evident in the scout base bay on the western shore, which supports the Whitebacked Ducks needs. Barry and Val Cleveland paddled the northern canals of the Marina down to Park Island bridge. They also checked the canal in the north western corner for Night Herons.
