Fontana Dam

Fontana Dam is a hydroelectric dam on the Little Tennessee River in Swain and Graham counties, North Carolina, United States. The dam is operated by the Tennessee Valley Authority, which built the dam in the early 1940s to accommodate the skyrocketing electricity demands in the Tennessee Valley at the height of World War II. At 480 feet high, Fontana is the tallest dam in the Eastern United States, and at the time of its construction, it was the fourth tallest dam in the world. The dam and associated infrastructure was listed on the National Register of Historic Places in 2017.

The dam impounds the 10,230-acre Fontana Lake, which spreads across a scenic stretch of the Little Tennessee along the southwestern boundary of the Great Smoky Mountains National Park. The Appalachian Trail crosses the top of the dam. Fontana is named for the now-inundated town of Fontana, a lumber and copper-mining hub once located at the mouth of Eagle Creek. The town's name was derived from the Italian word for "fountain."
