i know the pond you are talking about. never caught anything there either. they are there though. back in feb some guys went ice fishing with a cam and saw them swimming about. i think they stay in the north end on the pond were its deeper.
another pond to check out is hermitage park pond just off the yellowhead by the north saskatchewan river, also if the pond doesnt produce the river is a 2 minute walk and along that whole side of the park you can catch big fish.
third is you can try muir lake but its by spruce grove, one heck of a drive to get skunked.
also on the whitemud and north saskachewan river right beside the quesnell bridge by the spillway there is a pool you can catch goldeye on the fly.
