What 840.55 ft means

What each level means

Approximate by design — anchored to published thresholds (ramp minimums, full pool, spillway, records) but every cove is different.

1. Approaching the recordabove 858 ft

   The flood pool tops out near 860 ft; the 1964 record was 861.2 ft, when water reached the top of Allatoona Dam's gates.

2. In flood storage841–858 ft

   Above summer pool the Corps is storing floodwater; shoreline parks and courtesy docks flood first.

3. At summer pool837–841 ftnow · 840.55 ft

   Summer (full) pool is 840 ft — docks, ramps, and marinas in good shape.

4. Drawdown range823–837 ft

   Every winter the Corps draws Allatoona down well below summer pool; shallow coves and some ramps drop out. Normal in winter, notable in summer.

5. Deep drawdown815–823 ft

   Below the usual winter range — widespread ramp and cove impacts.

6. Near the record lowbelow 815 ft

   Approaching 809.3 ft (December 1954), the lowest level in the lake's record.
