Yes, on the classification rather than on a thermometer. WDNR has stocked brown trout into Bearskin Creek across 4 recorded plants, between 2015 and 2019, 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 54–66 °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 in the 1880s and now the fish most driftless spring creeks are managed for, reproducing without help across most of that footprint.
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.
Wisconsin DNR classifies this water as Class I, Class II, Class III. The management tier on those reaches is stocked, wild, wild supplemented. This is a designation of the fishery and not the season and creel rules.
