North of Atlanta, the lower section of the Chattahoochee is tailwater from Buford Dam that flows 48 miles southward into Atlanta to the Standing Peachtree Creek confluence. This outstanding lower section is quite popular with urbanites. While normally wadeable, during dam releases this section can be floated (watch for 5,000 to 10,000 cfs).
This section is managed for about 5,000 trout per mile. There are plenty of rainbow trout and brown trout. A 15 mile stretch north of the city of Atlanta from state route 20 to state route 141 (Peachtree Parkway) is restricted to artificial lures only.
Overall, Lower Chattahoochee River is the 6th most popular fly fishing river of all 12 fly fishing spots in Georgia.
