Don’t get caught trying for Salmon in the Waitaki at present, the season closed for Salmon end of March.
The river is however full of Salmo Salars! (Typical)
If you are ok with the canals idea, there have been some very big fish caught recently, the biggest I heard of was a 25lb Rainbow and another, a 24lb was caught by a local from Oamaru last week too. Shrimps, the pinker the better (nudge nudge, wink wink, say no more….)
No info on Dunedin south sorry to say….. over to another member for that fill in.
