Clarrie Hall and Tweed River Update
It has now been 4 months since the floods in March and Clarrie Hall Dam is still undergoing some change. The water is still coffee coloured but this will likely have a positive effect on the lake. It could be said that impoundments are in a constant cycle consisting of boom and bust phases. Clarrie Hall is probably in the latter phase now. My theory is that the elevated water levels and turbidity during the floods has cut off the cabomba weeds light source. Subsequently there has been a major die back of this invasive weed. The die off of the weed probably led to more turbidity which in turn caused more weeds to die. A kind of positive feedback loop. Hence 4 months later the dam is still turbid.
The good news is that much of the cabomba weed is now dead. This has exposed the edge of the lily pads making lure fishing a much easier proposition. The die back of the cabomba has also made access easier in a number of places including the boat ramp area which was previously choked with weed. The lily pads have had a bit of a shake up too and now there are gaps between the pads where anglers can swim a bait.
The Tweed River has also undergone some change. There has been some extensive erosion on the river bank where riparian vegetation has been removed for farming…..no surprises there. (River bank planting in these areas is desperately needed to stop erosion and siltation of the river.) However I was very pleased to see numerous new snags in the river. Some of these snags are absolute rippers and will no doubt hold good numbers of bass. On a charter yesterday Dan had some success fishing these snags with a Donny Brasco fly. On a number of occasions the bass appeared to be only sideswiping the fly but Dan managed to connect with a couple of nice fish. When the bass return from their spawning run in September there should be plenty of action to look forward too around these new snags!
