The recent warm weather has changed the fishing dramatically on the lake.  Although the crappies are still around the bite has slowed dramatically.  There are still guys who have been able to adapt to the changing conditions and are still able to catch them.  As the crappies have been slowing the bluegills have been picking up.  I have seen several limits from different guys of large bluegills in shallow water.  The question is what will happen with the cooler temperatures.  It most likely will push the bluegills deeper, and hopefully improve the crappie bite.  If you put in the time and adapt to the changing weather there is the opportunity to catch some nice fish on Lake Onalaska.
