May, June and July — those are the months with the most insects recorded from the Virginia mountains, 22 in May, 26 in June and 22 in July. Virginia DWR classifies it as Class III, managed as wild — that is the season and creel row to look up. This site reads the water as cold from VDWR's management tier for it, which is an inference from how the fishery is managed and not a temperature VDWR publishes, and no gauge on it reports temperature, so the calendar below is the hatch record rather than a thermometer.
27 insects peak in September in the Virginia mountains. By month, not week.

Insects peaking each month. Midges, scuds and sculpins are left out: they peak every month, so counting them would flatten the bars.

Virginia publishes no season on this reach in the file this site reads. Virginia DWR classifies it as Class III, managed as wild, and that is the row to look up in the digest — the season and creel rules follow the classification rather than the river. What the state designates on this water → Virginia regulations →
No gauge on this river reports water temperature. VDWR publishes no temperature classification for it either — the Cold band is inferred from VDWR's management tier for the fishery, which is a judgement about the trout and not a measurement of the water.
