AHD G6  2.86 @  09:22

AHD G2   rising from 0.88 to 0.96 within a period of 48 secs  @ 11:45

Wind driven waves travelling downstream to G2

Turbidity/ pH not taken

Water has drained from flats downstream of G4 but Rivernook flats & upstream have extensive deep water cover. Water flowing strongly through dip in causeway  at G4

AHD G2 0.55   @   09:55   AHD  G6 Water over the top of the AHD board

Very deep water across flats with extremely fast flow from upstream G6 to G4  -  no water cover over flats except small area immediately downstream G4 bridge, this area was draining back into the river channel- there was no water across OOR at flood markers or any other roads or tracks. G5 & G4 not sampled because of flooding.

AHD G2   0.91  @ 11:35           0.98  @ 12:35

Freshwater inflow difficult to estimate as waves were going upstream to 1.00m, then with slight downstream movement before returning upstream

Flats upstream to & around G4 have drained but visible water remains around G5 in lower areas. Large areas od water cover occur upstream of Rowans Gully
