Smallmouth temps are right; oxygen isn't close.

Water's sitting at 68.7°F — dead center for smallmouth — but the 24-hour DO range only reached 3.2 mg/L at its best, and that's genuinely stressed all day, not just a morning dip. Clear skies and sunny weather ahead won't help that number recover. I'd honestly wait this stretch out; it's hard to recommend putting fish through it right now.
