Green River tailwater fishes steady as fall cools the water

What's next

Flows are the story for the next few days. With 2,570 cfs at the lower gauge and 1,900 cfs at the upper one, expect a moderate, wadeable-in-places river that pushes fish toward edges, seams and softer inside water. If releases hold steady, temperatures should stay near 50 to 52°F, and the midday window from late morning through mid-afternoon is the best bet for active fish.

MidCurrent's recent Tying Tuesday notes that spare midge-style patterns excel in clear, pressured tailraces, which fits this kind of cool, steady water. Small, subtle patterns fished deep through the feeding lane make sense, and overcast days favor darker, higher-contrast flies per the same source. Mornings will be cold, so expect a slow start and plan to be rigged and walking by mid-morning. Check the gauges before you leave, since a release change can shift where fish hold quickly. The waxing crescent moon sets early in the evening, so expect little moonlight after dusk.

Context

Mid-October is typically the heart of fall in tailwater country. Cooling nights keep water temperatures in the low 50s, trout become more active than they were in summer, and fish often feed with more urgency ahead of winter. Streamer and nymph presentations commonly work alongside small midge and baetis imitations, and the window before the first hard snow tends to be short, as Field & Stream notes in its fall fly-fishing piece. Compared with a typical year, these readings look on schedule for the season. Check state regulations and any seasonal closures before heading out.
