Flysmallie, last time I trapped was mid September, around the time these photos were taken. I was only somewhat successful until the 3rd night when I pulled in a trap with about 25 that were "eating" size. I imagine you can catch atleast a few of any size year round. I'll get to work on trap building instructions soon and put them up here for you. I don't know how I'd do in mid-winter... haven't tried it yet. I plan on going again in late February to early March, and I'll let you know how I do then.
Blazerman, yep, that was from the Current, I think about 3 miles upstream from Akers. I was kind of surprised at how big that one was too. In the photo, I was trying to figure out how he got into my trap (there are only two 1 and 1/2 inch diameter access holes - the maximum legal size). I keep imagining he opened the access hatch, crawled in, and latched it behind him!
I baited the traps with small sunfish I'd fly fished in a creek behind my buddy's subdivision in Imperial. I'd frozen them before the trip in individual bags, then cut them up as I needed them for traps on the trip. I also had one small sucker I'd caught and prepared the same way, and they seemed to really like that.
