    Notes It rained the day before with very cold air temparatures. There was a strong inflow via the Keysers and Westlake Rivers with the water very turbid and muddy, visibility less than 15cm. The wind was from the SE with some high cloud covering. See the attached photos for an example of cloud cover. Immediately noticable was that the birds were missing for some inexplicable reason. The light was good, the temparatures were warmer than the day before. The mouth of the vlei was open, and the waterbodies were full, indicating a strong inflow from the catchment. Approx visible water flow rate on the water surface was 1 metre per 4 seconds at the railway bridge.
