Just paddled through it - a big lake with relatively few campsites, though the ones that there are are BWCA style; at least some have picnic tables and latrines, and are marked with bright orange signs.  A fair number of motor boat fishermen, but not crowded at all.  A fairly short moderate portage will take you into Crooked Lake if you want to get away from the motors, though I saw one motorboat there also (I think an outfitter keeps a couple of fishing boats there).  Saw one big fish finning near the surface going after bugs, otherwise, the fishing wasn't very hot because the weather was.  All the fishermen I talked too were only catching one or two fish a day.  If you go, plan on fishing at dawn and dusk.  They seemed to mostly be driving up or down the lake heading for structure.   If you are open as to when, I'd wait till fall, maybe eearly Sept.  The Mosquitos were pretty bad, black files mostly gone already now - should be mostly bug free in the fall.

Thanks for your responses.  I hope to get up to that area some time this fall and any information I can gather will help a lot.
