The Yellowstone Lake Crisis: Confronting a Lake Trout Invasion
Varley JD and Schullery P (ed). 1995. The Yellowstone Lake Crisis: Confronting a Lake Trout Invasion. Yellowstone Center For Resources, National Park Service. Yellowstone National Park, WY
On July 30, 1994, lake trout (Salvelinus namaycush) were discovered in Yellowstone Lake, Yellowstone National Park, Wyoming, the core of the remaining undisturbed, natural habitat for the native Yellowstone cutthroat trout (Oncorhynchus clarki bouvieri). Data from this and other lake trout caught subsequently by anglers and the U.S. Fish and Wildlife Service suggest lake trout have reproduced in Yellowstone Lake since at least 1989 and now number in the thousands, perhaps tens of thousands. A highly piscivorous, nonnative species, lake trout will probably thrive in Yellowstone Lake and reduce the lake’s cutthroat trout stocks substantially unless preventive management actions are taken.
