Without a map in front of me, it’s hard to point out some specifics but I’m on the lake almost every opener because it’s close to the family cabin.
From the Hwy. 40 launch, head south a ways and theres a rock pile with sharp drops on both sides. It comes up to about 3′ so be carefull when getting in that area but it’s a great spot to troll raps when cloudy or tossing cranks down the incline to see where the eye’s are. The darker, the shallower. At night they’ll get right on top of that pile.
Also, there’s an after dark bite if trolling cranks along the shorelines between 8 and 12′. They’re not consistant so you’ll have to fish until you find the magic depth.
Around to the east is a long point/sandbar that can produce fish readily. I’ve never found an big ones but the eye’s have been fairly easy targets off this point.
Also from the “40” launch is a big ol’ feeding flat with cribs in it. Dusk and dark often provides a nice eye bite too. I’ve had more success in the fall with this flat than the spring but I still see plenty of guys working it.
All around the lake there are endless possibilities as there is an abundance of structure and breaks. There are flats, sunken islands, gradual declines, sharp drops…………just tons of things to check on but the MAIN thing to keep in mind is the water clarity. It makes for challenging even your “goto” presentations. You have to be on your best game on Long or you may be in for a “long” day! Few are the “easy” days there.
SuperFluke is right about the bass on this lake…………plenty of 5#+ fish to be found if you target them, but put ’em back! It’s a trophy lake and should be treated as such.
If you’re going to be in Ladysmith, get some time on the Dairyland Flowage. It’s a typical river experience………….fewer anglers and some real BIG surprises in her! There’s good ‘eye action near you on the Chippewa River as well and I’ve read that the Thornapple area is pretty decent too.
From Ladysmith, truthfully…………..there’s an abundance of good fisheries within an hours +/- drive. Get a NW WI map book and check a few out!
