Yellowstone Lake Trout Problem [VIDEOS]| What Can You Do?

Lake Trout: The Primary Threat to Yellowstone Cutty’s?

As you may or may not know, I certainly enjoy fly fishing and catching Yellowstone Cutthroat trout has never brought a frown to my face.

Last year, my friend Dennis Kidd and I even set out to complete the Wyoming Cutt Slam. What a blast that was!

As such, I thought it important to help get the word out about the Yellowstone Lake Trout vs the native Yellowstone Cutthroat trout problem.

I’m sharing the current Yellowstone Lake Trout-Suppression Final Report National Park Service that has been going on for several years.

This is certainly a “hot topic” and one that has been debated for a long time.

Yet – no matter where you stand on the argument – I thought these videos were very informative and wanted to share them with you here today.

According to recent and ongoing studies, the Mackinaw or Lake Trout is indeed the main problem when it comes to the declining population of Native Cutthroat Trout in Yellowstone Lake.

Can anything really be done?

The data shared in these videos suggests a few directions that are being take and a few that are proposed.

Recently I attended and shot video of this excellent presentation put on by Wyoming Trout Unlimited YL Project Manager Dave Sweet.

Many are aware that there is a problem with Yellowstone Lake but do you know what that problem is? If you ever wanted to really understand what is going on at Yellowstone Lake – watch these videos to learn all about the Yellowstone lake trout problem.

The Dubois Anglers and Wildlife Group, a non-profit Organization in Dubois, Wyoming recently held a presentation by Mr. Dave Sweet, Project Manager for the Yellowstone Lake Project.

This was a fascinating presentation. I shot and edited this video project for the DAWGs and put it on their website. Decided that 2 posts is better than one and am also making a post about this presentation here. (Plus it gave me a chance to fix up a few errors I had on the first set)

After listening to Dave Sweet (Yellowstone Lake Special Project Manager, WY TU) give a presentation on the issue, I feel like there may be a glimmer of hope! Dubois Anglers and Wildlife Group (DAWGS) made a contribution to help purchase equipment for the research project.

Chock full of incredible studies about the battle between Yellowstone Lake Trout and their predation on the native Yellowstone Cutthroat Trout.

Tracking, telemetry, gill-netting efforts, surgically implanted trout and more are explained in great detail.
