Yellowstone Lake-End of an Era

[riverdog]

It has been shown that the lake trout in Yellowstone Lake came from Lewis Lake/ Shoshone Lake as adult fish. Since the lakes are on opposite sides of the continental divide it's pretty clear it was done by man. I don't remember all the details but otoliths from the fish reveal they spent many years in the other lakes before being transplanted. This went on for a couple years then stopped.
I imagine it's just too big of a lake to poison off all the fish and reintroduce natives.
