Hey boss, I'm in your neck of the woods! Fished all weekend on a private lake north of COMO.
I caught lots of dinks, probably only three decent fish 3lbs +. After that major front moved through Friday evening the fishing did slow down.
For what's it's worth, I downsized my bait to a T~rigged baby brush hog or zoom trick worm and the bite picked up for me. Showed down the retrieve, slow bottom hop.
Had my most success thoroughly fishing brush/standing timber and docks on rocky banks with quick access to deep water. I would darn near anchor on a spot that looked fishy. Had 0 luck at the back end of coves so I stuck to points and structure just off the main drag.
I've never been to Smithville but I hear folks over this way rant and rave about the crappie action.
Tight lines, and keep at it.
