"Officials Consider Whether Lake Trout Swam To Yellowstone"

"JACKSON, Wyo. — A new culprit is under suspicion in the unsolved case of who “stocked” Yellowstone Lake with nonnative trout, an ecological disaster now costing the government millions of dollars to control.

The conventional theory explaining the unwelcome newcomer, backed by some hard data, has been that a “bucket biologist” scooped lake trout out of nearby Lewis Lake and dumped them into Yellowstone Lake.

Suspecting foul play, officials offered a $10,000 reward in the mid-1990s for information leading to the arrest and conviction in the crime once dubbed “an appalling act of environmental vandalism” by former Yellowstone National Park Superintendent Bob Barbee. An emerging theory suggests the vandals might be the fish themselves."
