Matt released this data yesterday. Great to see that there are now more biomass of Brookies than the rainbows they replaced:biggrin: While I am generally cynical in nature, I wasn't about this, and hope all my friends that were cynical about this project will now go eat a healthy dose of crow;)

Anyway here's the report:



Lynn Camp Prong Update 2015 8 July 2015
The fisheries staff, with assistance from local volunteers, Trout Unlimited members, Great Smoky Mountains National Park (GRSM) interns and a group of outdoor writers, ranging in age from 7 to 82, conducted population monitoring surveys on the lower 3 miles of Lynn Camp Prong June 22, 24 and 25. Electrofishing surveys on Lynn Camp and a tributary (Marks Creek) indicate brook trout populations are at (15 kg/ha) or exceeding (>34 kg/ha) pre-treatment biomass of rainbow trout at all 5 sites. The data indicate there are now between 1,392-5,616 brook trout per mile of stream on Lynn Camp Prong. The upper end of the biomass range (>35 kg/ha) would be considered exceptional in terms of trout abundance for any GRSM stream. Both 2014 and 2015 produced excellent year classes of young-of-year (YOY) brook trout, which means there will be good numbers of adults in the next 2-3 years. In fact, YOY fish comprised 53% of the total brook trout catch across all sites. Of the adults collected in all sites, 23% were greater than 7 inches with good numbers of fish >8 inches. Catch rates of anglers have been reported in the 20-40 fish per hour range with the highest catch rates being reported farther from the trailhead.

The pre-treatment biomass of rainbow trout was used as a recovery target for the newly established brook trout population. Each site number represents 100m increments from the barrier falls.

Interesting read thanks for sharing. Glad to see that these projects are such a success and brook trout are successfully reclaiming and sustaining their territory.

1 mile. Similar results as to what my fishing has indicated. I'm glad to see it back open.
