63°F water is prime, but oxygen nags at me.

Smallmouth are squarely in their comfort zone with the river at 63°F, clear at 2.9 FNU, and flows holding steady around 314 cfs — on paper, it looks good. That said, dissolved oxygen at 3.2 mg/L is genuinely low, which can keep fish lethargic even when temps are ideal. Fish may be active, but I'd temper expectations and watch how they're responding.
