Not many lakes have complete Batho maps such as you are looking for. If you go on Google Earth and zoom into the lake of interest it becomes very easy to see all the contours and depths. I've used Google Earth to map a lot of Western Lakes and they provide some of the best resources as you can see the contours with your own eyes. Beyond that, you can google some lake names, adding the word map, contour map, batho map, topo map and/or fishing map and find contour maps that were done 40 years ago for most N. Western Lakes.
