One of my favorite venues, there is lots to know about Tzaneen. One basic thing you must remember is that Tzaneen is a points dam. What do I mean by that, the article on river channels is mostly based on information gathered on Tzaneen dam!
Firstly your morning fishing is ussually good using topwaters and spinner baits in the shallows. Also you should find the fish on either the points or in the back of the bays. Also keep a Super Fluke handy if you miss the strike on the top water. Keep an eye out for bait fish you normally see them scatter in the morning when the bass is feeding. Also throw top water when there is cloud cover.
When the sun is up the fish move a bit deeper, depending on wheather conditions this might vary from 6ft to 25ft. This is where the channels become important, most of the channels running into the main river channel have structure on them, this is stump fields, brush piles and trees. Here you can fish plastics, flukes, lizards, brushogs and jigs.
Flukes - Watermelon & watermelon candy slightly spiked tail
Spinner bait - Plain White or White & Chartruese
Brushog/Lizards - watermelon candy & green pumpkin spiked tail
Jig - black and blue
Trick worm - junebug, green pumpkin or pink
Unfortunetly do not have any maps with me but will try and explain areas I would consider. At the launch if you go right towards the dam wall the dam makes a turn to the left, as you come around the corner you will see brushes running far into the water, if you stop here you will also see a little island to your right. These brushes is on a drop off in the water. If you start fishing the brushes from the point right to the back you must find fish you will notice that the onse side is much deeper than the other side fish the deeper side of the brushes, I ussually throw a fluke on a number 0 mojo weight or spinner bait here. This is a migration point and these bushes keeps on re-loading. Also very good morning spot.
From here you will notice three legs splitting out of the main dam, you can try any three of these legs and look for secondary points and channels I believe most hold fish.
If you go to the left at the launch, the bau just before the bridge and the bay just after the bridge on the left bank usssually hold fish. There is a lot of trees in the water here, in the morning I will cas as shallow as I can and work lure towards boat. In the afternoon will fish the channel in about 10 - 15ft of water. Like to use the gp lizard here on a texas weight and be sure to stay in contact with the structure. In the morning also throw top water in the back of the bay. Go check out the back of this bay you will find it interesting.
The bay right across from the launch, the point on the left is also ussually good. There is a stumpfield here and I like to either throw a carolina 1/4 ounce or a mojo here with a trick worm. If the fishing is very slow I like to throw a pink trick worm in deeper water as this attracks a reaction strike.
Hope this helps!
Let me know.
