Hi Mark,
I had the same experience in md-June near Aitkin. The Bass would filter up into the cabbage beds in 5-9 feet of water during low light periods but during the day they were out along the deep weedline. I tried slip bobbering in 20 feet of water for Walleyes using leeches and caught over 20 Bass for every Walleye I caught….
There are different populations of Bass in a lake. Some fish are going to spend most of their time shallow in the heavy slop, and others are going to stay out deep along the weedline. It can be easier (and it’s certainly more traditional) to fish for the shallow Bass. But there are a lot of nice fish out deep and it can be very rewarding to seek them out.
They might not have been the Walleyes you were looking for, but I’ll bet those Bass were fun to catch!
