Yes, on the classification rather than on a thermometer. VDWR's trout-water designation on the South Fork Holston River names rainbow trout as a species it is managed for, and 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 — but no USGS gauge on this river reports water temperature, so this site has no measured July mean to hold against the 55–65 °F band this fish wants. Fish of 7–14 inches are what Virginia reports as typical.
Introduced. Wild populations sit in the steeper, faster mountain water, and stocked fish carry most of the put-and-take season.
No USGS gauge on this river reports water temperature, so there is no measured July mean to put beside the species' band. VDWR publishes no temperature classification for this water; the Cold band above is inferred from its management tier for the fishery, and it is not a thermometer.
Virginia DWR classifies this water as Class II. The management tier on those reaches is wild. Species Virginia DWR records in the classified water: brown trout, rainbow trout. This is a designation of the fishery and not the season and creel rules.
