What better way to start the new year than a day fishing for our native Australian bass. Matthew, a bream tournament angler was eager to sample the bass fishing in the Northern Rivers. We were lucky to have some low light overcast conditions in the morning at Clarrie Hall Dam which often results in some surface luring action. At this time of year under such conditions popping sounds can be heard as the bass suck in frogs, bait fish and insects from the surface among the lilies. However today the bass were holding down deeper. Plenty of fish could be seen on the sounder out in the open water at varying depths. There was no shortage of fish to target with the finesse hard bodies that Matthew bought with him.
Matthew worked the edges of the weed with his lures and was stoked to land a couple of bass for the morning. With the sun inflicting its punishing rays upon us we opted for some lunch in the shade of the pines at Crams Farm. After lunch we fished the Tweed River. By this stage the temperature had reached mid to high 30’s and the water temperature in the river was like a warm bath. The water at the dam was crystal clear in contrast to the rivers murky soup. We worked our lures for hours on the river but didn’t get so much as a touch. The bass were obviously shut down in what must have been very challenging conditions for them.
The Tweed River has seen very little rain in 2016 and it is showing signs of stress. With little rain to flush the system nutrients can build up in a water body. This initially promotes vegetation and algae growth. But as water temperatures and turbidity increases this growth can die off. The microorganisms that assist in the decomposition process have a high oxygen demand. The decomposition process ultimately strips the water of oxygen. Turbidity reduces available light and therefore photosynthesis and productivity is further reduced. The hot spell we have been experiencing warms the water which in turn reduces the capacity of the water to carry dissolved oxygen. The combination of these processes often lowers pH levels too. Bass could be seen on the sounder but there was no way they were going to feed in the river.
The dam however looks great! The water was so clear that fishing with a light fluorocarbon leader of about 6lb is wise so as not to spook the fish. A stealthy approach is also necessary under these conditions to ensure the best results. Bass could often be seen as streaks on the sounder that would rise diagonally towards the kayak. When the bass spot a boat or kayak they rise to the vessel out of curiosity. Once they spot you however, they are unlikely to fall for your bait. They must have seen many anglers before and know to be cautious. So, long casts, light lines and a quiet approach should all be part of the plan at Clarrie Hall Dam.
