64°F water, steady flow — but oxygen stays genuinely tight.

The 24h DO range topped out at only 4.9 mg/L, which puts this stretch in a legitimately stressed category all day, not just at dawn. Smallmouth are in their temperature sweet spot at 64°F, and flow is a manageable 203 cfs with the turbidity steady, so conditions aren't hopeless — fish may still respond, though activity could be sluggish. I'd keep expectations modest and stay alert to how fish are holding.
