Ron,

My guess would be chironimids, chironimids, chironimids.

I've fished them over here on the west side during winters past when I had cabin fever and just had to get out. The hatches I've encountered are usually good sized black chronies... about a 10 or a 12.

I forget the name of this one lake, it was out Sultan Basin way. Drug a canoe down to it. Didn't take into account the angle up... and had to use a tow line to help get the canoe out.

I'll be up for fishing Lenore next year. Shouldn't have too many outdoor projects like I did this year.
