Huge dam to be removed on Roaring River

History will be made soon as one of the largest dams to ever be removed in Tennessee wil be taken out. The aging dam on the Roaring River in Jackson County, Tenn. is being removed over the next few weeks for river and stream restoration purposes. The dam is roughly 220 feet across and 15 feet tall.

The Roaring River Dam is located about five miles before the beginning of the lake formed by the Cordell Hull Dam. The Roaring River is designated as a state scenic river and is a destination for paddlers, anglers and swimmers.

The dam was built in 1976 by the U.S. Army Corps of Engineers. It's being targeted for removal because the base of the dam is eroding in what is known as a “head cut,” creating a risk that it could fail. Rather than repair the dam, the Tennessee Wildlife Resources Agency and the Corps of Engineers determined that it would be better to remove the dam, which was originally built at TWRA’s request to keep reservoir species from migrating upstream into areas inhabited by stream fish. Fish surveys have shown that the barrier was not effective, and it is no longer needed. Click to read the U.S. Army Corps of Engineers environmental assessment.

“With the dam failing, it has provided an opportunity to enhance the connectivity within the Roaring River Watershed,” said Mark Thurman, TWRA Region 3 Fisheries Coordinator. “While the barrier has not excluded reservoir species, it does still function as a barrier through most of the year. Removing the dam will open up the river for fish such as white bass, sauger, smallmouth bass and redhorse. It will also benefit other species such as the eastern hellbender, whose numbers have declined across the species range.”

The eastern hellbender is a giant native salamander (growing up to 16 inches) that is listed as endangered in many states. In Tennessee, it is listed as a species of greatest conservation need. The salamander has been found both above and below the dam and its removal will reconnect these populations and allow for improved reproduction and overall species health.

“We know of more than 2,000 of these dams in Tennessee’s rivers and streams. Many have outlived their intended purpose and fallen into disrepair. There is a growing recognition that removing these old dams results in safer rivers for recreation and healthier habitat for wildlife,” said Rob Bullard, Tennessee and Cumberland Rivers Program Director with The Nature Conservancy.

Partners in the joint effort to remove the aging dam include TWRA, the Corps of Engineers, The Nature Conservancy, the U.S. Fish and Wildlife Service, the Tennessee Department of Environment and Conservation and the Southern Aquatic Resources Partnership.
