[quote PBH][quote kentofnsl]I wish they would explain in the article if that creek flows into or out of Yellowstone Lake. [/quote]
Atlantic Creek flows into the SouthEast Arm of Yellowstone Lake.
Looking at Google Earth, and using Utah's hunt map application, you can see that this hypothesis is not so far-fetched.
We've seen similar things happen in the past. A very good example is the Bear Lake cutthroat and the Snake River cutthroat. Some theories suggest that Bear Lake cutthroat evolved from Snake River cutts (not Bonneville), which is explained by a similar geological situation where the Bear River drained into the Snake River.
It is also a reason why we have found native Bonneville cutthroat trout on the Pine Valley mountain, which drains into the Colorado River.
While the examples I cited above are due to a geological shift, the Pacifc Creek / Atlantic Creek geological area provides a current avenue for fish migration during high water years -- maybe?
Fish are amazing.[/quote]
They are also thinking that many of what were previously called "greenback cutts " are now felt to be genetically Colorado River cutts that arrived at headwaters of Eastern draining creeks by similar means, and the true greenback cutts are a much more narrowly distributed fish, all based on genetic studies.
Not exactly the same comparison but didn't one of your family catch a somewhat scraggly looking lake trout in Lake Powell?
