BirdTroutOpen the map Is Smith Creek good for rainbow trout?
Yes, on the classification rather than on a thermometer. WDNR has stocked rainbow trout into Smith Creek once, in 2025, and WDNR classes most of its typed water as cold — 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. That is a stocking record and not a survey: it says WDNR put the fish in, not that anyone has since found one holding over. Fish of 8–16 inches are what Wisconsin reports as typical.

Introduced, and the least widely reproducing of Wisconsin's three stream trout: stocked broadly, wild in a smaller share of the classified water than brown or brook.
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. WDNR's classification of the typed reaches is Cold, and that is a classification rather than a thermometer.
| Gauge | Now | July mean |
|---|---|---|
| TYLER FORKS RIVER AT STRICKER ROAD NEAR MELLEN, WI | 58.8 °F | 69.8 °F |
What you may keep
Wisconsin DNR classifies this water as Class II, Class III. The management tier on those reaches is stocked, wild supplemented. This is a designation of the fishery and not the season and creel rules.
