    Yellowstone River disease outbreak is not affecting Idaho fish

    The disease that killed thousands of fish in the Yellowstone River in Montana is present in Idaho rivers, but Idaho Fish and Game officials have seen no large outbreaks or die offs of fish in Idaho rivers this summer. 

    The Yellowstone fish die-off is attributed to proliferative kidney disease, which appears to affect mostly mountain whitefish and to a lesser degree trout.
