I fish the small creeks in Columbia area during the late spring to early fall. I have never ventured into the water during the winter months. I am looking for suggestions on waders. Summer waders with heavy sock and some kind of long underwear or more winter oriented waders like the coldwater waders use in trout and steelhead streams? I am diabetic so my circulation in my extemities is not as good as non-diabetics so will affect my choices. I am tired of being house bound in the winter.
