The bluegill spawn came and went rather quickly.  You might still be able to find a few on beds, but a majority of them have moved to deeper water.  Lake Onalaska is fully into the summer pattern with most of the crappies moving out to the sloughs by the main channel or in the channel itself.  Perch and bluegills will be spread out with weed edges being good areas to try.  Bass and pike are hitting topwater really well, and the catfish have become quite active as well.  The weeds on the main part of the lake are not very bad yet, if you like fishing out there it is still fairly easy to get around.
