The river was very muddy and ebbing very quickly.

The river was in flood.

The EC measurements had to be estimated as the readings on the Hach meter would not stabilise.

Wind direction - S/SW

Beaufort Number - Fresh, 4-5

Sea state - rough to very rough

#15091 19 Oct 2022 Approved Notes:

EC readings would not stabilise. We took the average of the range.

While water appears cleaner than four days ago, it was still very brown and murky. There was no apparent debris.

The speed of the water flow made it difficult to get accurate depth readings.
