I don't know of any "real" depth charts for Wickiup. I have fished the lake for many years and I know the lake fairly well, costing me many $$$ worth or gear during that time. There are a lot of valleys leading into the lake, so when on the troll you cross them and lose a lot of gear on the high points. Here is a website (maptech server) that may help some. I am including a link to it with the "wickiup, or" already entered. You can play with the "scale" and "zoom" to get what you want. Notice the elevation lines which may give you a clue to the depth. Also, as you move your cursor across the map, you can see the latitude and longitude. This probably isn't what you want, but should help give you an idea. Here is the link, you may have to copy it into you browser,,,,this is a free service, but if the page comes up regarding buying, you just have to hit the "x" to close it out to continue.
