Oncorhynchus mykiss — introduced to Virginia, holding water between 55 and 65°F. Virginia's own fisheries records name 20 waters here, and the state stocks it into 20 more.
Virginia's rainbows are introduced and they sit in the steepest, fastest water the classification covers. DWR's coldwater layer carries a rainbow column, and the waters named from it here run from Rock Castle Creek and the Smith River to Crab Run, Redbud Run, Pass Run, Muddy Run and Helton Creek away in the southwest. Twenty more are designated stocked waters, which is where most of the put-and-take season happens.
Seven to fourteen inches, holding 55 to 65°F and tolerating 75 — a band that overlaps the brown trout's almost exactly and sits above the native brook trout's, so the three sort themselves by gradient and elevation rather than by county. Virginia does not set a size limit by species: the class on the water is the rule.

Typical length in Virginia is 7 to 14 inches. That is a curated range for water of this kind, not an average of any survey: MDNR's abundance file counts fish per acre and per mile and records no lengths at all, and no other state on this site publishes lengths either.
Introduced. Wild populations sit in the steeper, faster mountain water, and stocked fish carry most of the put-and-take season.
Waters VDWR records this species from, off the coldwater classification layer that rides on every reach in this map's Virginia footprint. Miles are of classified reach carrying the species, and the watershed is named because Virginia has five Mill Creeks and eleven Dry Runs.

VDWR's designated stocked-trout waters, with the designation each one carries.
Every subwatershed this site covers in Virginia as a faint dot, and the ones holding the waters listed above lit. A coverage map with this species on it — the map on the front of the site is the map.
Rainbow trout hold 55–65°F water and are under real stress above 75°F. On this map's own colours that band is cold, cold-transitional, cool water, which is what the river pages and the live map are painting when they run green and blue. The season follows the temperature rather than the calendar: the water is in the band early and late in the day through the summer, and all day either side of it.
Spawning: Spring — March into May — on gravel, which is what separates it from the two autumn spawners above.
What is hatching in Virginia, month by month, from the same seed the app's hatch panel reasons from. These are the state's recorded hatches, not this species' — trout eat what is in the water.

Faster, broken, oxygenated water: riffles, runs and pocket water, more often in the current than under the bank.
Patterns from this site's book, chosen by the insects recorded from Virginia's own regions and filtered to the kinds worth putting in front of this fish. Each one has its tying recipe.
Virginia does not publish its limits split by species: the bag and the season apply to trout as a group, by the class or category the water carries. So what follows is that, and not a rainbow trout rule dressed up as one. Snapshot taken 2026-08-16.
| Class | Bag | Season | Waters |
|---|---|---|---|
| Class i — wild, self-sustaining | — | — | 31 |
| Class ii — wild | — | — | 360 |
| Class iii — wild, limited | — | — | 169 |
| Class iv — put-and-grow | — | — | 72 |
| Other trout water | — | — | 2 |

Faster, broken, oxygenated water: riffles, runs and pocket water, more often in the current than under the bank.
The four thermal classes named there are the ones every river on this site is painted with, at breaks of 58, 64 and 70°F. A river page showing cold water is showing water inside this fish's band; that is the whole point of the colour.
The same fish, on different water and under different rules. Michigan's sand-bottomed rivers, Wisconsin's driftless springs, Minnesota's North Shore, Virginia's mountain brook water and North Carolina's tailwaters and freestone gradient are five fisheries, and the limits differ with them.
