Observation ID #761
Date and Time Thursday 10th July 2008 10:15am

Notes

Measurement repeated at 1.5m, because DO first showed 0.02mg/L and 0.5%, and although both these readings indicated a very low DO, these were extreme readings in comparison with those at 1.0m and 2.0m.
The DO readings at 10cm above the bottom were also very low.
