I dont know about oahe, but I think the smelt population at sak might be higher than usual, I just posted a picture of one I caught through the ice a few weeks ago, Every time I put a lure down in wolf creek area, there would be dozens of smelt around it in a few minutes, also the big pike havent been biting very well which leads me to believe there might be an over abundance of baitfish around also. I was just up there again on sunday and only caught one small fish, didnt see anyone catching much either.
