Since running any weighted system. The depth is determined by mostly by the speed that the weight is being pulled. If going with, across, or against the current also has affect on the depth. When you add in the variables like line type, line dia. etc there is no real answer. The best "known" chart is in your head. It is quite easy to set out one weight when at your trolling speed and direction. Semi slowly let out the weight till you touch bottom. Stop right there and once the baited system reaches the boat's speed. Typically a spinner blade will lift 3 to 5 ft. Let more line out and you will be closer to bottom. Do that a 3rd time and you should be dragging bottom.
Divide that first bottom contact number into the depths you want to cover. Say 45 out, 30 out and 15 out. For example. Change those numbers to 50,35,10 on the other side of the boat and you are covering the water column quite well. When the fish tell you where they want the bait. Move a couple rods at a time closer to the line out that caught at least 2 fish and you are starting to dial into the active biting fish. If that makes sense.
Doing this for just a couple days, you should have a real good idea on what line out numbers to use in the future in area's you fish. And when going to other area's, you will have a good idea on what numbers to use.
