Nickajack Dam and Lake
Site Description and Habitats
Nickajack Dam (river mile 424.7) on the Tennessee River was completed in 1967 and replaced the aged Hales Bar Dam that had been built by private interests in 1913. Most of the shoreline is undeveloped. The site is the beginning of the Tennessee River Gorge that is dominated by upland hardwoods mixed with Virginia Pines. Ridges rise to 1,200' with impressive limestone cliffs topped with Eastern Red Cedars with riparian woodlands in lower elevations. The water area is the main focus for this site and the river here has some large eddies and bays with substantial milfoil. There are trails in the wooded and shrubby areas.

Detailed directions for birding Nickajack Dam and Lake
From Nashville: Take I-24 toward Chattanooga and exit number 158. Turn right at the end of the exit ramp onto TVA Access Road. This road will lead you to the Dam, follow the signs to the dam and explore the recreation area and boat ramp and the area below the dam.
The area above the dam can be scanned from the recreation area and boat ramp at Shellmound Campground. You can also stop briefly (pull completely off the road) at the top of the dam and scan. Drive below the dam to the restrooms an parking lot and scan for gulls, waterfowl, and herons. Also drive further down to the powerlines and walk the gravel road through the shruby areas and explore the woods. In about 500m up the gravel road, there's a large wooded lake on the left side of the pwerlines to check out. You may need boots to get there!
On the way to the dam area, there's a large pond on the left and a big fancy gated entrance to a mostly failed subdivision. Drive through here to look for sparrows in winter, and Yellow-breasted Chat, Prairie Warbler, and Orchard Orioles in summer.
Be sure to check out nearby Marion County Park and other good birding spots in the immediate area.
