The Lahontan cutthroat trout in Nevada's Pyramid Lake are pretty uncommon.
There really isn't another trout species in North America (and possibly anywhere) that has the potential to consistently grow into the 18-25 pound range. But that hasn't always been the case with Pyramid Lake's Lahontans. Years ago, before diversions and barriers were installed on the Truckee River, these massive trout used to run from Pyramid Lake in the Nevada desert all the way up the Truckee to Lake Tahoe to spawn. That run, sadly, is now gone.
But thanks to a coalition of advocates ranging from the U.S. Forest Service, the Bureau of Land Management, American Indian tribes, local governments and local Trout Unlimited volunteers, the fish are once again making their way into the Truckee River to spawn.
A recent article on the Al Jazeera America site highlights the fish's return to its natal waters--perhaps one day, Lahontans will again make their way all the way into the Sierra to spawn in the deep, blue waters of Lake Tahoe.
