Sounds familiar. We also fished Tough Creek all day Saturday and Cottonwood south of the sisters on Sunday morning. A total of 2 big rainbows and 2 perch between 4 people. There was a group to the south of the point on Tough Creek that were catching a few, other than that it appeared nearly dead out there. It sounds like the fishing was bad everywhere in the state over the weekend, at least the weather was nice!!
The ice on Boysen is thick (14-18") and very solid, there is no overflow. The pressure ridges were not doing much either...
