Structure fishing like 90% of winter fishing requires excellent electronics, or a great memory of where and what time of the year, and how deep they were in the past.
My favorite spot of all time during the spawn has been one tree stump in 4' of water. Caught hundreds off that stump. Never knew why it was so good until getting good electronics with a hi def down scanner.
What I found is that it sits next to a 28' deep creek channel that has brush all up and down the side. The fish just move up and down the bank depending on the water temps and the timing of the spawn.
