Yes, the Colorado Division of Wildlife devoted quite a lot of effort to restoring "Greenback" cutthroats found in various locations in Rocky Mountain National Park and other locations east of the divide in the original range of the Greenback. Then a fisheries biologist came along and did DNA comparison with old museum specimens of Greenbacks and found that these fish were actually hybrids between Greenbacks and Colorado River cutthroat. Apparently Colorado River Cutthroats had been stocked east of the divide quite early. It turned out that pure Greenbacks were only found in one small drainage near Colorado Springs. Back in the '80's, I caught some cutthroats from beaver ponds in the Lost Creek Wilderness. I caught the cutts only in beaver ponds. In the creek that fed them, I caught only very small brook trout. This was a very small stream and there are no lakes in the drainage, so it doesn't seem likely that cutthroats would ever have been stocked there, but who knows? After all, the brook trout got there somehow. I've always wondered if these could have been true Greenbacks. I haven't fished that area since, so I have no idea of those cutthroats are still there. Part of the problem is that, prior to maybe the '70's, the game and fish people really didn't concdern themselves much with subspecies. Cutthroats were Cuttthroats, as far as they were concerned, and they stocked a lot of them outside their original native range.

Thanks!

Thanks!

Nice! Have fun!

Thanks Michael!

It was, because that's the only type of cutthroat in that drainage, but it definitely doesn't have the "fine-spotted" spotting. The fine-spotted spotting is much more, well, fine. Compare the spots on that fish to the ones on the last fish in the video. Thanks for watching.

Yep, pretty neat!

Nope, I've actually never caught a whitefish.

Whitefish.. come on bro-

Nope, but stay tuned. Thanks for watching.

They are all subspecies of cutthroat

Tenkara Addict thanks brotha!

No, it's not. It's the Colorado River cutthroat trout, which is different from the greenback cutthroat.

The Greenback Cuthroat is native to the South Platte drainage (east of the continental divide). The Colorado Cutthroat is native to the Colorado River drainage, including the Green River drainage in Wyoming. They are closely related ssubpecies, as the Greenback likely evolved from Colorado Cutthroat that got across the divide due to a stream capture.
