In the bottom 1 m of seawater at august St bridge hydrogen sulfide gas clearly detected. Indication of rotting vegetation, supported by very low and zero DO levels. This could indicate aftermath of high level nutrients (eg sewage spill), which needs to be investigated.
John Inchley rang Shire Health Officer, Peter O'Brien to inform him of data and he said they would investigate further (reported Mon, 29 Jan).
Jan Jones to investigate the use of drone to photograph estuary (and creek) with Balcombe Grammar.
