Green River browns and fall smallmouth stay fed as water cools
Water across the Green River system is sitting in the low 50s, a range that keeps fall feeding steady. Gauge 09261000 reads 51°F with 3,390 cfs, gauge 09234500 reads 50°F at 2,300 cfs, and gauge 404417108524900 reads 51°F. Per Wired 2 Fish, October to mid-November is prime time for big spawning brown trout moving out of larger waters and into feeder creeks and rivers, and that article describes Ontario. The same seasonal pull applies to brown trout in cooling Western rivers, so treat it as a pattern rather than a local report.

Temperatures this close to 50°F suggest the bite is driven by cooling water and shorter days, not by heat. Expect fish to stay active through the middle of the day, when the water is warmest, with the best window running from late morning into mid-afternoon. Mornings may start slower after a cold night.
For trout, Hatch Magazine and MidCurrent pattern roundups point to low-light, overcast days favouring a beaded purple nymph and midge-style flies in clear, pressured water. Streamers that bounce the bottom, such as a pine squirrel jig, are another option when the water is moving. With flows around 2,300 to 3,400 cfs, fish seams, inside bends and softer edges, not the main current.
For smallmouth, Field & Stream advises following forage to deep structural edges as water drops into the 40s and 50s, using oversized baits. Tactical Bassin adds that a bladed underspin or swimbait works well when bass are chasing baitfish in fall. If a cold snap pushes temperatures lower, slow down and fish closer to the bottom. The first quarter moon gives decent evening light, so a late session is worth planning.
Context
Mid-October is the shoulder of the season for this region. Water in the low 50s is on schedule for the date: summer patterns have faded, fish are shifting off shallow haunts, and brown trout typically start staging ahead of fall spawning. Check state regulations before fishing, since some waters carry seasonal closures or special restrictions during spawning periods.
