Hot afternoon ahead — fish early or wait for rain.

At 73.76°F the river's a touch above smallmouth's sweet spot, and dissolved oxygen has been maxing out around 3.7 mg/L all day — genuinely stressed, not just a morning dip. With a high of 90°F on the way and a slight chance of showers, conditions could shift either way, so I'd say manage expectations and keep sessions short. Worth a look, but I wouldn't bet the day on it.
