A single shore entry dive by Gary and David of 55 minutes. Maximum depth 5.7 m, 20 C water temperature (rounded up) and maximum 8 m viz.
A shorter than usual immersion courtesy of a couple of equipment failures. We probably only covered about 10 lineal metres of river bed but managed nevertheless to sight more species than we sometimes record in dives of three times the duration and ten times the distance covered. The substrate has been significantly altered due to the recent river bed profiling operations.
