A lot of them around today
Jumping in lake right after bugs came out. Alas no fishing pole or license here.
Caught and release several grayling from Cascade Lake in Yellowstone National Park. While grayling are native to the park, they are not native to the upper Yellowstone River drainage, of which this lake is a part. It's likely these adfluvial fish were stocked in Cascade years and years ago.
Caught a Yellowstone cutthroat trout inside Yellowstone National Park at Cascade Lake.
Just a little guy.
