There had been a heavy rain storm during the night which we later discovered had resulted in news reports back home. In the morning we found that our boats were floating. The river had risen by about a metre overnight and covered the previously exposed rocks along the river banks and was encroaching a little on the vegetation line.
The water level was higher than we had seen before. We figured that it would continue to rise through the day as heavy rain had only just eased and lighter showers were continuing. Everyone felt it was at a reasonable level and were keen to paddle on.
The first rapid which exited from the large, calm pool of Rafters Basin was wide and shallow as well as very long. Jamie was keen to get moving and led the way. He called back directions to the rest of us and used hand signals to indicate the best route through the rapid. We all negotiated the rapid through the much stronger current and larger volume of water than we had been used to without any problems. It was not a steep drop, making it fairly easy, and the speed of rafts on this more substantial current was exhilarating.
The first few rapids of the day got us very excited. We were charging along at break-neck speed and having a ball. Even where the water was flat the current was very fast. The fast strong current in flat water produced a very odd feeling in an inflatable raft. It would invisibly push or pull the boat in unexpected ways and occasionally it would hold the boat in place with water rushing past. Presumably this strange tangle of strong currents was produced by the rush of water rebounding off boulders hidden below the turbulence of the dark and furious river.
