Although it is not well-known, the infinite wisdom of Yellowstone fishery biologists has sometimes been a bit strange. In 1893 they stocked bass in the Gibbon (unknown whether they were smallmouth or largemouth). In the early 1900s, they put largemouth bass in Goose and Feather lakes (Firehole drainage). And in a real act of folly, in 1908 they dropped 7000 Atlantic salmon into Yellowstone Lake. Thankfully none of these introductions survived (although the Gibbon would be an interesting smallie stream). As a consequence of the Goose Lake introductions, Yellow Perch showed up there and survived until the late 1930s when they were poisoned out. I wish the biologists had more sway in advocating the extirpation of clueless tourists who don’t follow the rules.
