After months of watching reservoirs shrink and stream gauges plummet, Georgia caught a break in May.
Metro Atlanta recorded more than five inches of rain during the month — well above the historical average and enough to rank May 2026 among the wettest on record for parts of the state. The rainfall recharged topsoil moisture, greened up parched lawns, and provided meaningful relief to farmers in south Georgia who had been drawing heavily on irrigation wells.
But state officials said it wasn’t enough to declare the drought over.
Where things stand
The Level 1 Drought Response declared by the Georgia Environmental Protection Division on April 27 remains in effect, despite the wet month. While the most extreme drought classifications have been downgraded in several regions — particularly south of the metro area — large swaths of the state remain in “severe” or “extreme” categories.
Lake Lanier, the state’s most closely watched reservoir, has risen from its April low but still sits roughly four and a half feet below full pool as of Wednesday. The Army Corps of Engineers’ target is 1,071 feet above mean sea level; the lake was measured at approximately 1,066.6 feet this week.
Why the rain hasn’t been enough
Hydrologists explain the gap with a concept they call the “sponge effect.” After months of dry conditions, Georgia’s soils were so parched that much of May’s rainfall was absorbed into the ground rather than running off into streams, rivers, and reservoirs.
That groundwater recharge is a necessary first step — plants, wells, and aquifers all benefit — but it means reservoir recovery lags behind rainfall totals.
“Think of it like pouring water into a dried-out sponge. The sponge has to fill up before any water reaches the bowl underneath.”

Additionally, the timing of rainfall matters. Scattered afternoon thunderstorms — common in Georgia’s spring pattern — produce intense but localized downpours that don’t always fall within the Lake Lanier watershed.
Flash-flood paradox
Ironically, some of the same storms that helped ease the drought also caused flash flooding in metro Atlanta. On May 20, heavy rain flooded sections of the Downtown Connector and parts of Midtown, stalling traffic and prompting water rescues. More storms hit May 24–26.
The paradox — drought and flooding happening in the same month — is a hallmark of Georgia’s humid subtropical climate, where dry spells can end abruptly with intense rainfall that overwhelms urban drainage systems.
Looking ahead
Forecasters warn that the relief may be temporary. The long-range outlook for late June and July calls for higher-than-normal temperatures and below-average precipitation across much of the Southeast — conditions that could stall or reverse the drought improvement.
The EPD said it will continue biweekly assessments and does not plan to lift the Level 1 response until Lake Lanier returns to within two feet of full pool and soil-moisture deficits are substantially erased.
