Overview

Observation ID #16032
Date and Time Wednesday 21st February 2024 10:00am

Notes

Approx 0.4m of black sludge above bottom.  Exceptionally clear water enabled us to see the weight disappear 0.4m before it touched bottom!  This may account for strange bottom depth readings previously seen at A5
