Arkansas River
The best month to fish the Arkansas River is April. The month to avoid is July. Right now, in August, it is worth going.

- April: 90 out of 100
- May: 55 out of 100
- June: 44 out of 100
- July: 40 out of 100
- August: 71 out of 100
- September: 71 out of 100
- October: 83 out of 100

- December: 62 out of 100
Water averages 68°F this month — fishable, but the margin is thinning. Fish early, land them fast, and stop when the afternoon heats up.
- The water is 8°F warmer than normal for this month — 75°F right now against a typical 68°F.
- At 75°F this is above the point where a fought and released trout often dies anyway. Whatever this month usually looks like, right now is not the time.

WHERE THESE NUMBERS COME FROM
Flow and water temperature are medians of the monthly means reported by USGS gauge 07096000 over 1999-2018. Air temperature and precipitation are ten-year normals from Open-Meteo at this river’s gauge coordinates.
The window is deliberate. USGS’s own full-record statistics for a dammed river reach back before the dam — at Lees Ferry, to 1922, forty-one years before Glen Canyon closed — and describe a river that no longer exists.
Flow is scored against this river’s own fishable band of 386–586 cfs. There is no universal band: 8,000 cfs is low water on a big tailwater and a flood on a spring creek.
Water temperature is a ceiling rather than a weight. Above about 68°F a trout that is fought and released frequently dies anyway, so no month above that line is scored as worth booking, however good its flow.
The Arkansas River is at its best in April — water around 51°F, flows near 339 cfs.
