Does the cooler water temp more than compensate for the lower dissolved oxygen levels?
I do not have a clue!
However, one option is to use some heavier tackle, especially if you are worried about catching a HSB while fishing for your largest LMB.
It is not as sporting, but if you just "horse 'em in", then the HSB cannot turn their heads and make multiple exhausting runs.
P.S. In my neck of the woods, the middle of May is still cool water temps. What are the temps in your main pond now?
