Trout like this one were first introduced into the waters of Sixty Lake Basin in the Sierra Nevada nearly a century ago. The fish flourished, creating a paradise for anglers. They also devoured tadpoles and froglets, nearly wiping out native amphibians like the mountain yellow-legged frogs. Trout stocking was stopped here in Sequoia and Kings Canyon National Parks in the 1970s, and now national park staff are working to net out the fish from many lakes in hopes that reduced predation will help frog populations recover.
