#12223 27 Jun 2018 Approved Notes:

I have had another look at the dissolved oxygen DO results for 27/6 as we were concerned about the very high readings. I went back to Augusta Street bridge the next day and took another reading which was considerably lower. Unfortunately I didn’t retest the other sites. I now believe that the meter was incorrectly calibrated so I think we should include a note to that effect on the data sheets. On re-reading the calibration data I didn’t allow enough time for the DO reading to stabilise.
I will allow more time for future calibrations. Jan Jones

#12177 25 Feb 2018 Approved Notes:

No stratification (sea water). Lack of stratification possibly due to the creek being very low (not flowing) for 2 months due to lack of rain. High tides and very strong westerlies (sometimes gale force) have probably pushed the seawater back up the estuary. The estuary flowing in reverse with resultant seawater.

All samples of nearly pure sea water.

Lower than usual pH samples. pH meter checked against standard afterwards.

Met with Peter O'Brien on Monday 19th at Augusta bridge site tot discuss last months data. He as going to investigate storm water drains, including current citation oval damage to explain high B.O.D. and EColi count.
