Wow, you are lucky!!! I’m jealous.
I look for them suspended in deeper holes. Sonar is a necessity. Often times they suspend anywhere in the bottom half of the water column. My best luck has been with small (1/8th ounce) jigging spoons (Go Devils work great) tipped with the head of a fathead. Watch for them on your sonar and tease them up. I find that they usually bite when the lure is still, but some jigging will get their attention. I usually get a few on a live fathead under a bobber, too, but not as many. I know some guys will fish a small chunk of cut bait under a bobber, as well.
The bite is usually pretty light. I like to use a spring bobber cause a lot of times they will just nibble it. I find I hook a lot in the skin of the lip or the whiskers.
It’s not too complicated, but it’s addicting. Hold on, it feels like you set the hook on a cinder block.
Let us know how you do!
