No USGS gauge on Lower Twin Creek reports water temperature, so this report is the hatch record and the classification rather than a live number. October is Blue-Winged Olive, Cranefly, Green Rock Worm / Green Weenie and Crayfish in the Virginia mountains, across the state line — 8 insects are recorded as active.
No gauge on this river answered with a temperature when this page was built. That is a gap in the gauge network, not a judgement about the water.
