I fish there often, more often as I think I should, hehehehe. Never been mugged, never been bothered.
Patience is the word. I can safely say that 3 out of the 4 times I go there, I land a fooshie. The weather plays a big role in fish biting there. The past week we felt the first of the cold. Give it 3 days of sunshine and good weather, then go.
Cast near fallen tree stumps, inbetween reeds and 1-3m along the dam wall, focus on areas with small bits of structure along the dam wall.
Good luck.
