Notes:
- Fish death event. 145 fish collected, 100's more small dead fish along each side of estuary around G2.
- After the artificial opening the water level dropped by a metre over night.
- Some dead fish on ledge near entrance suggest that many fish have gone out to sea in the strong current. (discharge straight out to the south).
- Fish death event mainly from stranding by sudden water level drop and caught in vegetation and algae. Oxygen levels were also very low (0.55mg/L at G2)
- Banks of channel about 0.3m near the estuary, rising to 3.5 near ocean. The channel is 20-30m wide near the ocean.
- Discharge around the mouth and south out to sea for over 100m.
