Observation details

Overview

Estuary Powlett River Estuary
Site Site six (Fishing Hole)
Observation ID #5140
Date and Time Saturday 18th May 2013 10:04am
Approved Approved

Notes

River width and lack of access made it impossible to read bottom depth.
The bottom sample of water had a very strong odour. The low oxygen would indicate that there was very little movement of the deeper water leading to anaerobic conditions.
