DELICATE WATER ZONE · D0 — Abnormally dry over a member dam

Atlanta, Georgia

Metro Atlanta drinks mostly from Lake Lanier — the prize in a three-decade tri-state water war that reached the Supreme Court — with Allatoona carrying the northwest suburbs. Both are Corps reservoirs measured against conservation pools that guide curves lower every winter; a dry autumn here reads as a falling percent on two dials at once.
