Ok reason I wanted to know is to make sure you understand the size of this water. Traditionally Tzaneen dam is what I call a points dam, as you know this dam have a huge amount of main points and a hell of a lot of secondary points. What you want to do is to focus on the main points that is where you will probably find most of your fish, you will either find them on the main points or right at the back. If you tried this and had no luck THEN only try secondary points. The structure is obvious and visible.
The lures will use is as follows:
Topwater: Popper, Plastics: flukes, brushog and dead ringer. Colors Watermelon, Green Pumpkin and Junebug if you have cloud cover. Rigs small texas and mojo.
Good luck
