I caught males really shallow on 5/6 and 5/7, at that time the females were still holding deeper in the same area, which was south of the 245 bridge. I did catch a couple bass up shallow too.
Unfortunately I was broken down until the 16th, I have not been able to find any fish up on the bank in the same area as before, aside from dozens of carp.
The fish that I have caught this week while trolling were mostly females, and they still had eggs but were not ready to burst like they were before.
I'm no expert either, but I know that things like water clarity, temperature, and weather patterns will all affect the depth that they spawn in, and those factors can vary considerably from one end of the lake to the other.
