No doubt. On Union the night bite will always be at least twice as good as fishing during the day. I use a cheap old coleman gas latern set on the edge of my boat for light to attract the fish. The key for me has always been to make sure I'm on my spot before the sun goes down and have the latern setup and ready. Right now the south end is where you'd want to try fishing at night (I can give more detail via PM). Sometimes you'll pull up on a dock or row of pilings right before sunset and the crappie will already be there and feeding right below the surface. If you setup on a spot like that you'll catch crappie all night long down there. You'll have to weed through the little guys like always but the catching can be fast. 70% of the time I'll be casting/tightlining pilings. The other 30% I'll be making cast toward the shore.

You need the right type of shoreline though....deep (5-6 feet deep right at the shore) rocky flat that breaks to even deeper water. Almost like a good perch hole would look. There's an old saying "if you're catching perch, you're fishing too deep"...because perch and crappie will often times use the same type of feeding areas but the crappie will be up shallower. Don't forget out the marinas too. Most of them are set on top of deep water with hard bottoms....have pilings and boats for the crappie to use as ambush points....and best of all they have plenty of light during the night.
