Green River browns and bass slow into the fall transition

What's biting

What's next

Expect water temperatures to keep drifting down through the week, which tends to slow metabolism and push fish toward steadier, more predictable holding water. Plan around the warmest part of the afternoon, when a degree or two of warming can wake up a sluggish bite. Early mornings will likely be quiet on the bass side, so slow your presentations and downsize.

If flows hold near current levels, the river sections should stay fishable and the cooler water favors Brown Trout feeding more actively through midday. MidCurrent's recent Tying Tuesday features point to small, low-light patterns, including a beaded purple nymph for overcast days and midge-style flies for clear, pressured water, which suit this kind of cool, steady flow. On stillwater, Largemouth Bass and Smallmouth Bass should hold near remaining green cover and shallow structure, per Fishing the Midwest's advice to find living weeds in the fall.

The waxing crescent moon offers modest light in the evenings, so dusk and dawn windows are worth a look without expecting a major lunar push.

Context

For this part of Utah, mid-October typically sits in the settled fall pattern, with cooling water, fish feeding ahead of winter, and lighter angler pressure as many head to the hunting woods. Readings in the low 50s are on schedule for the season. Check state regulations and any seasonal closures before heading out.
