There are several access points / parks along the Chattahoochee River in metro Atlanta that are part of the National Recreational Area that include some popular fishing spots. Lots of the area below the dam can be covered by walking up from outside the local hatchery. The Island Ford area may be affected, I haven't fished that area enough to know if there is a gate they may have locked closed. There are also a couple of areas with boat ramps that are probably now inaccessible.
