Prolific Blue-Green Algae.

Condition of water  - dark green and murky, meant that we could not carry out the Phosphate, Nitrate or Nitrate tests.

Blue-Green Algae forming on various areas of the lower lake

Phosphate - Unable to determine besause of discolouration of the water.

Nitrite - 1

Nitrate - 10

Phosphate = 0.7

Nitrite = 0

Nitrate = 10

Nitrate = 0.0

Nitrite = 0.5

Phosphate = 0.05

Nitrite = 0.0

Nitrate = 0.0

Phosphate = 0.05

we were unable to measure Temperature, Dissolved Oxygen and Electrical Conductivity because our multi-purpose meter was under repair.

Phosphate reading =  Top = 0.07        Bottom = 0.02

Nitrate reading  =          Top =   10        Bottom = 10

Nitrite reading  =           Top  = 1          Bottom = 1

Phosphate = 0.02

Scans of the Data Sheets have been forwarded to Deirdre Murphy

New Physio-chemical Data Sheets required before next monitoring date

The pH meter could not be correctly calibrated, therefore pH readings were not taken from top and bottom samples

The pH meter failed the calibration test, coming up with ERROR 4.

We used the meter to take pH readings, the results were 

Top    = 6.6

Bottom  6.9

Because we cannot be sure of the accuracy of these readings, we have not included them in the results.

Seriously bad haxards.

Too Toxic to carry out records

Diabolical!  Action required

Blue-green algae infestation of the river, particularly near the boat ramp.

No Fresh water

Large bed of thick blue-green algae behind the pontoon.

Very bad smell from the river

Water where algae mat is not floating on the surface is very cloudy, 

Hach meter kept on shutting down.  New batteries fitted, no problems after.

Bad Buue-Green Algae present.

Very strong, unpleasant smell

No photos were taken during this monitoring session.  Photos are to be taken later in the week

River re-opened, and running fast, brown in colour.

No signs of blue-green algae.pH meter did not show a smiley face after a 5 minute wait, the test was repeated with a new sample and was completed satisafactorily     

Bird life abundant

No wind, brilliant sunshine                               

The water at the Curdies Estuary is putrid with Blue Green Algae, to the extent that the surface is coated in a thick scum close to the shore.. The water is like pea soup over the entire depth, but the smell is more like an open cesspit.

The Caravan Park adjacent to the river is constantly getting cancellations because the tourists cannot stand the terrible smell.  Local resicdents are also complaining about the terrible smell.

The river was putrid with Blue-Green Algae.

Sludge was backed up around the boat ramp, between the pontoon and the shore, and up onto the shore in most areas.

The smell was disgusting, an obvious health hazard.

Where the sludge was not present, the water was more like soup.

The pH readings taken were considered high, so the meter was re-calibrated and new samples re-tested, with identical results

The LaquaTwin pH meter failed calibration several tlmes..

Calibration results were: -

pH 7   12.4

pH 4   11.2 

The pH meter readings must be considered suspect.- data removed

pH readings could not be taken because when we were calibrating the meter, the results fluctuated, and error message E3 and E$came up.

We had requested repair or replacement of ths meter some months ago. 

Ph readings could not be taken because the Ph meter could not be calibrated.

We did not monitor the site at Curdie Vale because the monitoring site was under water
