Is the Johns River good for rainbow trout?

Yes, on the classification rather than on a thermometer. NC DEQ recorded rainbow trout in the Johns River between 2007 and 2022, at one sampling site on it, and this site reads the water as cold from NCWRC's management tier for it, which is an inference from how the fishery is managed and not a temperature NCWRC 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 North Carolina reports as typical.

Introduced, and now the most widely distributed trout in the western counties — wild in the tumbling gradient water and stocked through the hatchery-supported season.

Is the water cold enough

No USGS gauge on this river reports water temperature, so there is no measured July mean to put beside the species' band. NCWRC 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.

What you may keep

North Carolina WRC classifies this water as Wild Trout Waters. The management tier on those reaches is wild. This is a designation of the fishery and not the season and creel rules.
