Southeast idaho catfish?

[PalisadesPorter]

I've caught a few channel cats at mctucker ponds just south of Blackfoot, but only one over 20" in several trips. I also heard they started to stock roberts gravel pond with channel cats again but they would all still be pretty small. Swan Falls may still be too far away for me to consider an afternoon fishing stop, though I'm not opposed to a good multi day fishing pilgrimage. Has anyone ever caught anything big out of Alexander over by Soda Springs? I've heard they have catfish but I don't know if it is too cold there for them to ever make it much past 3 lbs
