1. The Chattahoochee River Marker
Inscription. From Buford Dam downstream to Peachtree Creek in Atlanta, the Chattahoochee River showcases a unique ecosystem unlike any other southeastern United States river. Built in 1956, and located at the southern end of Lake Lanier, Buford Dam is the main reason why the River is the southernmost trout fishery in the eastern United States. The cold, clear water that flows out from the bottom of the lake through the dam's power generators rarely rises above 50 degrees Fahrenheit – supporting a diverse population of aquatic and terrestrial species.

Sign made possible by:
Upper Chattahoochee Chapter of Trout Unlimited (ucctu.org) and Chattahoochee National Park Conservancy (chattahoocheeparks.org).

(caption) 1. Rainbow Trout (Oncorhynchus mykiss) Stocked throughout the year in the Chattahoochee River, this cold water fish requires water temperatures to be consistently below 65 degrees Fahrenheit to thrive.

(caption) 2. Brown Trout (Salmo trutta) The cold, clear water supports a wild, reproducing brown trout population in the Chattahoochee River.

(caption) 3. Bluehead Chub (Nocomis leptocephalus) Male bluehead chubs build gravel mounds for females to lay their eggs and are often used for habitat by other aquatic species.

(caption) 4. American Bullfrog (Lithobates catesbeianus) The call of the American bullfrog is a distinctive on a southern summer night, but not many people know that they are voracious predators that can consume small birds and rodents.

(caption) 5. Spotted Salamander (Ambystoma maculatum) Although large for a salamander, these critters are hard to spot, but if you do find one it would indicate a healthy ecosystem.

(caption) 6. Chattahoochee Crayfish (Cambarus howardi) Regularly found in the northern portion of the Chattahoochee River watershed, this crayfish with bluish-green coloration can be found in riffle habitat from the smaller tributary streams to the main river.

(caption) 7. Mayfly (Ephemeroptera) A vital food source for fish, these insects spend most of their lifecycle underwater as nymphs and can live for several years before they hatch as adults.

(caption) 8. Shoal Bass (Micropterus cataractae) Identified in 1999, the shoal bass is one of ten black bass found in the state of Georgia and is native to the Chattahoochee River.

(caption) 9. Great Blue Heron (Ardea herodias) The Great Blue Heron is the largest of the North American herons and often stalks the shallows of the riverbank, waiting for fish to swim within striking distance.
