rate that weights sink

[beckoning]

I troll for salmon and trout in Lake Michigan. Sometimes, instead of downriggers or lead core or dipsy divers, I like to "long line" whereby I have a spoon 200' behind the boat. I add torpedo shaped weights to take the spoon down. Otherwise, the spoon skips on the surface. The problem is I don't know how much torpedo-shaped weight to add at 2mph trolling speed. There must be a graph that would show for every 1 ounce of weight at 2mph, the weight will sink so many feet. Has anyone seen such a graph?

Yes, such graphs exist

If I understand the chart correctly, to get a spoon or body bait down 35', I need to let out 100' of line and have 16oz of weight on the line? That is much, much more than I had thought would be the case.

That is correct. If anything, the weights are on the "light" side.

Now you know why people use down riggers

Torpedodivers.com will give you an accurate depth chart for their divers. http://www.walleyesinc.com/walleyeinc3/onlinestoreprecision.htm

Usually for snap weights 1 oz will give you about 5' of depth if you let it back about 50'
