Fall shift settles in on the Green River tailwater
Early October marks the turn on the Green River tailwater, and the calendar is the most useful thing to plan around this week. With the moon at last quarter, expect the cooling-season shift that anglers below Flaming Gorge usually notice first in the mornings and in shorter afternoon windows.

Over the next two to three days, expect the seasonal drift to continue without a sharp change, so the current pattern should hold. Cooler nights will keep mornings slow to warm, which favors fishing the first hours of daylight and saving the midday hours for shade or structure. If a cold front moves through, expect a shorter feeding window and a quieter bite for a day or so before things settle. For planning, weekend trips are best approached with early starts. The moon is heading toward new, so nights will get darker over the coming week, which only matters if you plan to fish after dark. Check Utah regulations before you keep anything.
Context
For the Green River below Flaming Gorge, early October sits in the handoff from summer to fall. Tailwater temperatures are set largely by how the dam releases water, so they change more slowly than air temperature, and that stability is why the tailwater often stays fishable through the seasonal change. Typical for this region, the bite tends to concentrate in the warmest part of the day as the water cools, while the coldest mornings slow things down. The timing looks on schedule for this part of October, neither early nor late.
