NON-TIDAL CHANGES IN SEA LEVEL AND TIDAL STREAMS

Water level within Port Phillip is much affected
by winds blowing for a long period in one
direction and may remain above mean level
continuously for some time after southerly
gales, or below mean level continuously for some
time after northerly gales. 
At about the time of high and low water in the 
entrance the stream runs at its strongest, 
4-7 knots. For details see Australia Pilot 
Vol II NP 14.
