I fish the Green Bay/Sturgeon Bay area.  I'm new to smallmouth fishing.  

As Spring progressed, I kept moving North to catch pre-spawn fish, and I was doing very well.  Now, in the Southern areas, it's post-spawn, and I'm lucky if I can average one fish per hour.  Mostly, I'm catching small males.  I've tried many different baits and depths, and nothing seems to be working.  I know where they spawned, and I know where they'll be in the Summer, so I feel like I should be able to catch more of them.

Does anyone have any tips for locating/catching post-spawn fish?  Maybe it's just not a good time to fish for them?

I would try and find the deepest structure you can find, close to where they spawned and drop shot it.
