Okay, that saves me typing a bunch of numbers!! ;D
Torch Lake, Elk Lake, & Lake Skegomog make up the main part of the Chain of Lakes. We used to fish this with the Michigan BASS Federation.
Given the choice, I would concentrate on Skegemog. Quite a bit smaller (2,700 acres) than either of the other two, and holds a combination of LM & SM Bass. If I was there this month, I would start in the narrows between Skegemog & Elk lakes. Nice saddle back and with any kind of westerly wind, you'll get quite a bit of current moving through there. After that, I'd work the deep weedlines in 16'-18' range.
If you are going to stay on Torch Lake, it isn't that hard to fish. While it is approx 18,770 acres in size, the average depth is something crazy like over 100'. That pretty much leaves you to working the shoreline drops or weedbeds. You may want to have a drift anchor if the wind kicks up out of the North or South. Just keep covering water until you hit a fish or two and then slow down.
Lures? Pop-R's in the morning, followed by crankbaits (shad or perch), then soft plastics. My top choices for soft plastics include 3"-5" Kalins Grubs, Tubes, Yamamoto Grubs, and ribbon tail worms of course. Top colors have always leaned towards light colors like Avacado, Sand, or Motor Oil.
Good Luck!
