I live in KY and live but a few miles from a small lake that was, once upon a time, stocked with walleye. I don't quiet know how to explain the details of the lake but it tends to get deep, up to 80 ft in spots. My dad and I have caught walleye both trolling deep cranks and on live minnows (mostly while crappie fishing). Just wondering if anyone could help me with other techniques. If any other lake info is needed just let me know, Ill try to answer the best I can.

Here is my personal best caught a few years ago. 8 1/2 lbs while trolling a chrome/blue back Norman DD22 over about 30-40 feet of water at night

I have caught the majority of my walleyes in 18-30 feet of water.  I catch them using one of two methods.  The first you already mention and that is pounding deep cranks into humps, points, flats and ledges in that water depth.  The second is dragging a live bait rig across those same areas slowly.  The rig is basically a split shot rig with a sliding sinker and a swivel instead of a split shot.  (Google Lindy Rig).  

A tactic I like to use when night fishing or ealy morning/late evening is fishing with slip bobbers over rocks in 18-25 feet of water.  I like leeches, but minnows and night crawlers work well too.

I have no idea if the walleye have different behaviors in the south, but that is a fool proof plan up here in the north.

PM me if you have any specific questions, I've been walleye fishing since I was a little kid.  

I have used vertical jigging on KY lake in the past.  Get some 1oz lead ball head jigs and some plastic shad bodies ( i like chartreuse wih some sparkle).  Put the shad bodies on the jig head and then attach a stinger treble hook to the jig hook.  Put a minnow on the stinger hook.  Just drop this off the side of the boat and bounce it off the bottom. I used a 7' MH bc and 12# line.

I was fishing for sauger but that is pretty close to a walleye, although we caught a share of drums to.

During the night walleye will come really shallow (sometimes 2-3ft) and this is when they like to feed. So go out during the night and target deep drop offs, say from like 4ft to 20ft, the waleyes will be hanging out around there. And during the day use orange jigs and mister twister grubs and jig over these drop offs, as well as run deep diving crankbaits along them.

I'd try trolling crawler harnesses with inline planer boards.They're a deadly summer technique.Caught these a couple weeks ago doing just that.

Thanks for the advice guys. Walleye fishing is something I'd like to do more of.

Went out last night for some bass fishin...caught maybe 3 or so small ones but my dad decided to troll flats along the way back to the boat ramp. Caught this little 3lber at the edge of a large weed flat that rises from 50 or so ft up th 12-15 ft. Caught it on a series 3 strike king bleeding shad.
