Title: Observations on communities of brook and brown trout separated by an upstream movement barrier on the Firehole River

Journal Article · · Prog. Fish-Cult.; (United States)

Division of a fluvial fish community by stream impoundment can give rise to dissimilar upstream and downstream assemblages which may themselves differ from the original community. These changes are often ascribed to the modification of physical habitat or water quality. Less well documented are effects on fluvial fish communities of an upstream-1 movement barrier alone. Observations were made on contrasting communities of brook trout (Salvelinus fontinalis) and brown trout (Salmo trutta) separated by Kepler Cascades in the Firehole River of Yellowstone National Park, Wyoming, a series of waterfalls that form an upstream-movement barrier.
