Low water level in estuary with sand bar partially exposed & drying algae draped over veg. at E side of estuary. Waves entering shallow over wide area / dense sea mist & air temp about 18C. |

Notes:
AHD G6 over AHD board @ 07:48 G2 0.65 @ 09:35 Turbidity G6 34 NTUs pH 6.8 Very cold North wind 5 Monitoring difficult because of very fast flow. Probe attached to rope with 4 weights. The use of weights raised the height of the probe above 10 cm from the bottom both at G2 & Lt1 The turbidity water sampler was possibly dragged about 5m.downstream in the very fast flow so bottom readings may not be accurate |

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 |

#12193 | 22 Jun 2018 | Approved |
Notes:
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.

Notes:
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 |
