On lakes it dont matter. Fish the whole point! If you have good electronic use them to locate bait and bass. I.e. Traditionally Fork my home lake, fishes poorly when the gates are open. (I think this is more of an excuse for guides on a bad day) when they are open releasing water down river into the sabine. It creates current but we would never know. Ive seen fish relate to points up stream, down stream, and right on top. Start where you graph bait or activity. Simple
