Notes:
According to Mike Linsell the fish in the estuary have moved upstream. This would be consistent with the D.O. results.
Nick Wison's new green Estuary Watch cap matches his scarf nicely.

Van Dorf out of action.
pH monitor not able to be calibrated so we used the pH strips.
Team coordinating beautifully in Estuary Watch raincoats.

Notes:
Fast flowing water in both directions created very turbulent water at about 1.5 metres and so the readings for salinity were very unstable. Measurements were taken on the high tide so the incoming tide was meeting the fast flowing fresh water caused by resent high rainfall.

Notes:
Following a few days of high rainfall there was a very strong current. The fast flowing water made it difficult to accurately measure the depths so there will be greater error in the depth measurements. The current also prevented the Van Dorn from settling on the river bed. It was pulled along in the current.
The water appeared to be very muddy and the turbidity readings confirmed this. A possible reason for the high reading may be to do with the above average rainfall this winter and the fact that much of the surrounding farmland has been turned to mud by cattle. A greater amount of this sediment would be washing down the surrounding tributaries as the wet winter drags on and the mud increases. Also there have been reports of many landslips in the Powlett catchment due to the high rainfall this winter.

Notes:
Very strong out going current dragged the van dorf even with the weight so it was difficult to know if we reached the bottom.

Notes:
Accidentally kicked turbidity tube into the Powlett. It has gone to join the old lead weight from the Van Dorn. Robbie was working very hard to get the job done quickly due to an overwhelming urge to clean his house.
Young lady fishing below the bridge pulled in healthy quantity of seaweed.
The results indicate that there is very little fresh water on the surface of the river..

Notes:
The river remained at the same height from the start to the finish of the monitoring. The sand build up at the mouth may be preventing the river from emptying out. There was a small amount of flow from the mouth into the sea.
