Yes, on the classification rather than on a thermometer. Michigan stocks rainbow trout into Mitchell Creek, and MDNR classes most of its typed water as cool — 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 8–16 inches are what Michigan reports as typical. The river is designated Type 2 and Type 4 trout water, which is what sets the size and creel limits.
Introduced from Pacific-slope stock in the 1880s. The lake-run form — steelhead — is the same species, and the rivers that hold resident rainbows are largely the rivers steelhead run.
No USGS gauge on this river reports water temperature, so there is no measured July mean to put beside the species' band. MDNR's classification of the typed reaches is Cool, and that is a classification rather than a thermometer.
