planer boards info needed

Hi, we want to try to troll using planer boards, I know there are many
factors that effect the depth of the lure. Such as: line size/type, weight
of lure, sinker weight, how much line is out ahead of the lure, speed of the
boat and most likely more that I have not thought of. My question: Is there
some kind of chart/book that one can use to help figure out how much weight
vs. amount of line out will equal a certain depth in the water at different
trolling speeds? We will mainly be fishing on medium/large sized fresh water
lakes for walleye, lakers & stripers. The trolling speed we plan to fish at
will be 1-1/2 to 2. Thanks for any advice, we have never tried this before
so we can use all the help we can get.
