Notes:
For some reason, I was unable to calibrate the HACH meter. The option to check standard for LDO101 would not highlight. I turned the meter off numerous times but got the same result. I did check its accuracy by comparing a result of 1413 micro Siemens/cm against the analytical reagent of 1376. Assuming this result was in the ball park, we went ahead with monitoring. |

Notes:
We were not able to calibrate the Ph as tube of test liquid was empty. Consequently, we used Ph strips from the kit. |

Notes:
Very strong outgoing tide, so consequently hard to measure depths. pH measured using litmus paper as meter couldn't be calibrated. |

Notes:
pH meter would not calibrate (Error4 message) - instead we used the pH paper kit. |

Notes:
The river was very muddy and ebbing very quickly. The river was in flood. The EC measurements had to be estimated as the readings on the Hach meter would not stabilise. Wind direction - S/SW Beaufort Number - Fresh, 4-5 Sea state - rough to very rough |

#15091 | 19 Oct 2022 | Approved |
Notes:
EC readings would not stabilise. We took the average of the range. While water appears cleaner than four days ago, it was still very brown and murky. There was no apparent debris. The speed of the water flow made it difficult to get accurate depth readings. |

#14405 | 15 Dec 2021 | Approved |
Notes:
The 50cm markers of the depth monitor need adjusting. Turbidity was les than 9 on top and bottom. We did not do monitoring at B2 (fisherman jetty) and B5 (Taits Point) as the water appeared very dirty due to sewerage discharge into the river as a result of the Barwon Heads sewer system failure event requiring emergency work by Barwon Water over the past few days. We considered the state of the water to be a potential Health and Safety issue. |
