Every stream in the Great Smoky Mountains National Park is open to fishing for the first time since 1934.

Different streams have been unavailable to the public on and off since the park opened in 1934, and a recent reopening of 8.5 miles of Lynn Camp Prong was the last to be closed. The prong was closed due to biologists working on the removal of invasive rainbow trout for over six years.

“The opening of all streams in the park to recreational fishing marks an incredible milestone for the park and speaks to the commitment and dedication of our biologists and partners in restoring fish populations in the Smokies,” Park Superintendent Cassius Cash told WBIR.

The biologists were working to protect the population of the native brook trout, which were threatened by the presence of the rainbow trout, and say it is now safe to fish for the brook trout recreationally.

The national park has 2,900 miles of streams to fish. License requirements and other fishing regulations are available from the National Park Service.
