Sorry to report a bit of a fail really.
The jigging was very hard - we all managed 1 or 2 but only small fish that were all released. Conditions were variable - from 2-3 knots to 10 knots . Not bad at all. Lots of smelt sign - more up eastern end of lake.
Spoke to a chap in a stabi who was at anchor - he ended up with 6 averaging 4lb!! He was up Otaramarae end of lake.
We tried all manner of smelt flies, the new jelly bean flies, bullies and kilwell no 1 flies. Uv flies, lumo sinkers.....
Lots of fish would follow up to surface without striking - but they were not monsters.
Jigged from 20m to 43m - mostly 30-35m
Trolling with lead line we got one really nice 2.5kg rainbow in perfect nick plus 2-3 others that were a bit small.
We tried a downrigger and got a couple more small ones on that. Lots trout marking in 20-30m quite often in much deeper water.
Back to the drawing board im afraid but think that anchoring in a prime spot or using electric gps motors are a distinct advantage over drifting like we were doing.
