Here are a few areas I would look. I have never seen this lake and like others stated, there are several other factors at play when looking for pre spawn fish such as bottom composition, brush piles, baitfish, bank angle (steepness), etc. I would pay attention to all factors in these areas. If I was starting I would look at the spot shown with the north cove and what appears to be steep banks on both sides leading into a good protected spawning cove. Again, I have never seen the lake, just trying to help you figure it out. Good luck!
