Fall trout window opens on the White River tailwaters
Cooling nights are pulling the White River system into its fall trout season. USGS gauge 07060500 reads 62°F with 3,040 cfs moving, while gauge 07060000 shows a cooler 53°F, so temperature varies a lot depending on where you fish. Cold-water zones near the dams hold the best conditions for Rainbow Trout and Brown Trout. Gink and Gasoline stresses scanning for dark shapes and subtle movements before you wade in, and Trout Unlimited notes that adding enough weight to a nymph rig is often the difference between getting bites and not. Caddis Fly (OR) calls the Perdigon a hot fly this fall, and the same compact, heavy profile suits tailwater nymphing.

Expect steady cold-water conditions in the upper reaches, with the 53°F reading at gauge 07060000 showing where trout are most comfortable. The warmer 62°F reading downstream should keep easing as nights cool, which pushes fish to feed more actively through the day.
A New Moon tonight means darker nights and typically stronger low-light feeding at dawn and dusk. Plan first and last light for the most active periods, then switch to deeper nymph rigs through midday. MidCurrent describes a beaded purple nymph for overcast, low-light days, and a spare midge pattern for clear, pressured tailrace water. Both are worth having on hand. Flow stage matters most here, so check the generation schedule before wading, since heavy releases change both safety and where fish hold.
The smaller tributary gauges at 07075000 and 07060710 read 70°F and 66°F with very low flow. Those warmer, thin waters are less suited to trout this week, so favor the main tailwater stretches.
Context
Early to mid October is on schedule for the shift from summer patterns into fall. Tailwater trout typically feed more aggressively as water cools and day length shortens, and Brown Trout begin moving toward pre-spawn behavior. Terrestrial patterns fade while nymphs, streamers and egg imitations gain value. Flylords Mag highlights the Atomic Egg as a simple pattern for fish keying in behind spawners. Check state regulations for seasonal closures and special-regulation sections before harvesting.
