I am very familiar with dale. It is by far my favorite lake. So anyway if i were you i would throw a chartreuse spinner bait in the backs of creeks with trees in the water, Also on points at the mouths of coves and creeks. Then i would throw a green tube or a jig in backwaters of dale hollow. And also on main points of the lake try throwing abright colored crankbait like a red or blue.

Good luck
