Badbrad, I always try to set up in water 20'-35' deep. Most of the time the fish are caught between 10'-18' deep. I usually start out with one line down 10', another 12', another 14', etc. I fish 5 rods at different depths until I see a pattern as to what depth the fish are gonna bite. Once determined I set 'em all within a foot or so in depth. Now, I say "usually" cause during the cold months we caught alot of fish right on the bottom. Not know your water conditions I'd stagger the depths until I started getting bites then adjust the depths.
I like fishing clear water. I believe the light drawing the baitfish penetrates the water farther in clear water vrs. stained water drawing in more bait.......thus drawing in more crappie. When you get started fishing try different places to learn more about your lake. Some spots will be better than others. Some places might not pay off at all. You wont know until you go. An hour or so before dark I like to ease around in the area I plan to fish to see if I can see balls of baitfish on the graph prior to anchoring too. Someitmes I dont see 'em but still catch fish. Smetimes I see the bait but dont do so good on the fish. You just never know. I guess that's why they call it "Fishing" and not "catching"!!
Oh, and by the way, dark nights are way better than bright nites. This is one thing I've watched this year and light nites turns the fish off. If the moon rises late you're alright but if the moon is already up when it gets dark you wont do as good.
Go fishing. Report back what worked good and ask questions about what changes you might can make. There's alot of experienced night stalkers on these forums that might be able to give you some good advice. Good luck!
