Bear River (Lake) Cutthroat Trout
Oncorhynchus clarkii utah (variety)
The Bear River/Bear Lake Cutthroat Trout has an interesting history. It is considered by most to be a "variety" of the Bonneville cutthroat. Although the Bear River terminates in the Great Salt Lake within the Bonneville Basin, the Bear River cutthroat seem to have differently than the Bonneville cutthroat trout. It is believed that the Bear River, as the result of geological or perhaps glacial activity, changed from it original course. Many think that the Bear River was connected to Bear Lake and the Snake River drainage further north. As a result, the Bear River and Bear Lake cutthroat trout are thought to have a genetic connection to the cutthroat trout in the Snake River and Yellowstone drainages.
I listed the Bear River/Lake cutthroat trout because of its somewhat unique characteristics and the fact it is popular enough and appears to have reasonably healthy populations.
