No posts here in a long while...not too surprising. What I can tell you is not much has changed. Plenty of catchable walleye and bass every year all in the 10"-14" inch range. Plenty of bluegills, pumpkinseeds and especially rock bass, for the kids. Every few years you get a good run of keeper panfish. Perch, when you can find them, tend to run small.
About 17 years ago (2002) the DNR experimented with stocking trout, but they didn't take (likely due to the lake's infertile water) despite a vast majority of the lake being deeper than 20'. Many publications will list rainbows as being present here, but they are long gone.
There's possible remnant populations of smallies, crappie and northerns, as they have all been caught in the past. A few bullheads here and there. And every once in awhile, a good ol' esox shows up to remind you that his kind are still lingering in Long Lake's crystal clear waters.
Most fishing these days is done related to the weeds and downed trees along the shore and the L-shaped rock bar crossing the middle of the lake. Many cribs installed 20 or so years ago were hot spots for a long time, but most have begun to deteriorate and aren't holding gamefish like they used to. In high water years, the "Loon Bay" on the south end can be very productive, but please avoid during nesting season.
