I have fished this lake since the early 90s quite frequently.
It is a very clear water lake which is primarily lake trout, walleye and bass. It can be very tough to fish from time to time especially for walleye.
When you are headed up there is a good chance that you will get into some lake trout. Often we catch them trolling a shallow in the spring as well as drifting with jigging spoons.
If you are looking for numbers of trout (and not size) there are smaller adjacent lakes to portage to that hold trout.
There are some very large walleye, bass and trout in the lake.
