Exploring river systems during drought conditions is never a good idea. On my latest trip, many hours were wasted in the attempt to find enough water to hold fish. Most of the bigger pools had turned a nasty green colour and the idea of inflating the float boat to enter the slime seemed crazy.
Hot, oxygen deficient water usually means tough fishing, as a rule the morning session usually provides the better results with such unforgiving conditions.
Strangely the small pools looked a little healthier and a lot less affected by the dry conditions; my main goal was to explore the river and find what fish the river held, while knowing there was so much stacked up against this particular trip.
