From the north Georgia mountains to the Florida border, the Chattahoochee River is impacted by unplanned development, storm runoff and trash from industries, roads, and construction sites, and discharges from sewage treatment plants. Withdrawals from the river by municipalities and industries also affect its health through consumptive loss of water that is not returned to the river, impacting downstream water quality, recreation and ecology. While significant improvements have been made in the river, much remains to be accomplished.
