JACKSON, WY — Yellowstone Cutthroat Trout are on the brink of extinction. But one man has spent over a decade working to bring them back.

A new film from KGB Productions follows Dave Sweet as he works tirelessly to restore Yellowstone Cutthroat. The trailer just released, and it’s sure to inspire anglers, conservationists, biologists, and just about anyone who cares about the natural ecosystem that surrounds us in Jackson.

The film follows Sweet and his daughter, Diana, a fisheries biologist, as they travel into the infamous Thorofare area of Yellowstone, the most remote wilderness in the lower 48, to Sweet’s if his efforts have been successful and if the trout has returned to its native spawning runs.

“A lot of people thought that it was too late. That there was nothing that could be done. I refused to accept that,” Sweet says.

The trek in is two days on horseback through some of the most rugged terrain in the west with the highest concentration of grizzly bears outside Alaska — combined with extreme weather and unrelenting mosquitos among other challenges. Working with multiple environmental groups and government agencies, Dave has spearheaded the fight to save this native species that is said to impact over 40 species in this pristine ecosystem. Once there, he will get to witness first hand if these native fish have returned.

Local music fans might recognize the voice of Aaron Davis from Screen Door Porch. Screen Door Porch has two original songs, “Pay it Forward” and “Wrong the Right,” featured in the film.
