I've never fished Kaw Lake, usually at Ft. Gibson, Tenkiller, Hudson, or Kerr. My wife and I drift fish for cats all the time.Most of the time we do pretty good. Seems like drift fishing is good for 10# and under - jug lines get the bigger ones.
Shad population seems to vary from lake to lake. May not be a bad idea to take a few with you from home.
