Hi Zac,
A friend of a friend went there about a month back and trolled up heaps of small cod and a few yellas.
I saw the pics so it appears to be true.
Hava look at the water resources site and see how much water they are letting out for downstream irrigation. If they are letting out heaps theres a good chance you will get zip as the freshies seem to go quiet when theres a big outflow.
I was goin to go there myself but my dear old mum wanted to go to see her sister at Inverell and she cannot drive long distances so Copeton it is for me n Kat.
Cheers, steve.
