However, due to primitive logging techniques and the introduction of non-native rainbow trout, many populations were lost at the end of the 19th century. Nowadays, wild brook trout populations are only found in the coldest and cleanest headwaters of the mountains of East Tennessee, at elevations above 3,000 feet, where the water temperature is usually below 68° F. To expand the range of brook trout, TWRA biologists have been working with the United States Forest Service, Great Smoky Mountain National Park, Tennessee Aquarium, and Trout Unlimited to reforest native vines in their native waters. Rainbow trout is native to the Pacific drains of the western United States but has become the most abundant and distributed trout species in Tennessee due to extensive trout management throughout much of the 20th century.
Wild populations are now found in about 300 streams in eastern Tennessee. Rainbow trout spawns in late winter and their young are born in early spring. They can tolerate slightly warmer temperatures than stream trout, and prefer water temperatures below 70° F. Brown trout is native to Europe and Asia and was naturalized in Tennessee through repopulation.
They are usually found in lower-altitude streams and often coexist with rainbow trout.
