Your method is still ok in the winter months,maybe change to smaller or larger bait and spit shots.

Yeah the river looks GREAT and relaxing just wished it looked that way year round.
I only use jigs but your minners will work the same way as a jig if worked the same way.I start looking for them in the eddies,usually start in the middle of the eddie.I cast a 1/16 and let it fall to the bottom,let lay for couple seconds and hop it 1 to 2 ft. off bottom and let fall back to bottom,repet 3 or 4 times.Reel in cast 3 to 4 ft. to the side of the area just worked,repet all the way to shallow and deeper water.If no takers try again with a 1/32 repet as above and do not to forget and change colors if no takers on the one your useing.
When useing jigs or minners this time a year a crappie nibble and or a spray on scent may be needed if the bite off limits.
Wednesdays bite was hair putting until I found what they wanted which took 3 hours with nothing in the cooler.In 30 mins. I was headed back up river with a limit of the prettest Ky.bass I've ever seen,thanks to the clear water.
Shad are dieing right now so a minner and small spit shot as to let it fall slowly to the bottom may be the right thing to do.Who knows what they want but I keep a pink crankbait tied on just in case they want something different....Meaning if you aren't catching do something different.
