Chattahoochee River Professional Review and Guide
"Two sections are worthy of note. The lower river upstream from Atlanta is an outstanding tailwater fishery. Don’t overlook the upper river in the mountains near Helen. You can count on the thumb of your left hand the number of major cities in the South or anywhere else in the nation, for that matter, that have a great trout stream running through their centers. But that’s just what the Chattahoochee brings to Atlanta, thanks to the frigid outflow from the base of Buford Dam about 45 miles north.
The suburban ‘Hooch is the section of river that gets all the glory, but high in its headwaters in the mountains above Helen, the river is quite good for both wild and stocked browns and rainbows. Species: Brown, rainbow, few brook. Angling methods: spin, bait, and fly-fishing."
