the book "LAKES OF WASHINGTON", VOLUME 2, EASTERN WASHINGTON, SECOND EDITION, published in 1964 lists 89 unnamed lakes in pend oreille county. they are listed by township and range, but even if you could figure out which one you are interested in, the info in the book doesn't tell you much. none of the named lakes are called "wolf".

somebody apparently told you the name, "wolf lake"; can that person give you more info?
