Notes
AHD G6 3.90 @ 08:15
G2 0.76 @ 08:40
Strong N wind 4
Water very dark & dirty
Recent heavy rainfall (G6 16/09/17 20 ml o/n) has caused levels to rise again with water over/bank from G6 -G4. At G4 water is up on the concrete deck & over top of causeway but just starting to go over/bank immediately D/S of bridge - no flooding on flats beyond this point. Water is across OOR near flood markers but passable by 4x4. Flooding from run off (N - S flow) only
