The U.S. Drought Monitor map is updated each Thursday to show the location and intensity of drought across the country. The map uses five classifications: abnormally dry (D0), showing areas that may be going into or are coming out of drought, and four levels of drought: moderate (D1), severe (D2), extreme (D3), and exceptional (D4).
This map is used by USDA to trigger disaster declarations and loan eligibility. Individual states and water supply planning may utilize additional information to inform their declarations and actions.
The U.S. Drought Monitor is a joint effort of the National Drought Mitigation Center, USDA, and NOAA.
This map shows precipitation for the past 30 days as a percentage of the historical average (1991–2020) for the same time period. Green/blue shades indicate above-normal precipitation, while brown shades indicate below-normal precipitation.

The Lawn and Garden Moisture Index measures the capacity of current soil moisture to sustain healthy lawns and gardens.
The index is computed in two stages. The first involves how much recent precipitation (over the past 21 days) contributes to current soil moisture. The second involves finding how much the total effective rainfall for the current day differs from a “standard” amount of rainfall considered to be adequate for that time of year to sustain healthy lawns and gardens.
Positive values of the index indicate adequate precipitation or better, while negative values indicate a precipitation deficit.

Current and forecasted lake levels for U.S. Army Corps of Engineers (USACE) projects in the ACT and ACF River Basins. Where applicable, lakes are color-coded based on USACE lake action zones*, which provide guidance on meeting minimum hydropower needs at each project and determine the amount of storage available for navigation, water supply, and water quality. Click on any of the lakes to view the current lake level and (where available) the 1-week forecast (measured in ft MSL, feet above mean sea level).
* Forecasts are not available for R.F. Henry and William Dannelly. For Lake Seminole (Jim Woodruff Dam), which has no action zones, green = below maximum operating level, and blue = above maximum operating level. Navigation restrictions in the action zones below do not apply to Allatoona and Carters, as navigation is only directly supported for reservoirs in the ACF Basin.
The ACT River Basin contains sixteen reservoir projects—five managed by the U.S. Army Corps of Engineers and eleven managed by the Alabama Power Power Company (APC). This map shows the eleven APC-managed projects within the ACT River Basin—seven on the Coosa River and four on the Tallapoosa River—as well as three nearby projects on the Black Warrior River.

The U.S. Drought Monitor (2000–present) depicts the location and intensity of drought across the country. Every Thursday, authors from NOAA, USDA, and the National Drought Mitigation Center produce a new map based on their assessments of the best available data and input from local observers. The map uses five categories: Abnormally Dry (D0), showing areas that may be going into or are coming out of drought, and four levels of drought (D1–D4). Learn more.

Drought results from an imbalance between water supply and water demand. The Standardized Precipitation Index (SPI) measures water supply, specifically precipitation. SPI captures how observed precipitation (rain, hail, snow) deviates from the climatological average over a given time period—in this case, over the 9 months leading up to the selected date. Red hues indicate drier conditions, while blue hues indicate wetter conditions. Data are available monthly from 1895–present. Learn more.

| W3 | #0000FF | W3 (PMDI of 4.0 to 4.9) Tree rings were used to reconstruct a Palmer Modified Drought Index (PMDI) value for each June–August, estimating relative dryness. The PMDI value for this location is 4.0 to 4.9, indicating extreme wet (W3) conditions. |
| W4 | #0000AA | W4 (PMDI of 5.0 or greater) Tree rings were used to reconstruct a Palmer Modified Drought Index (PMDI) value for each June–August, estimating relative dryness. The PMDI value for this location is 5.0 or greater, indicating exceptional wet (W4) conditions. |
In paleoclimatology, proxy climate data (e.g., tree rings, ocean sediments) can allow us to reconstruct past climate conditions before we had widespread instrumental records. The Living Blended Drought Atlas, shown here, estimates average drought conditions each summer (June–August) as far back as the year 0 by combining tree-ring reconstructions and instrumental records. Red hues indicate drier conditions, while blue hues indicate wetter conditions.
Drought Response in the ACT River Basin
The ACT River Basin contains sixteen reservoir projects. The U.S. Army Corps of Engineers (USACE) Mobile District operates five federally owned reservoirs, while the Alabama Power Company (APC) owns and operates the remaining eleven dams—seven on the Coosa River and four on the Tallapoosa River.
In times of drought, the USACE and APC work together to enact conservation measures across the basin’s reservoirs, following the Alabama Drought Response Operation Plan (ADROP). This plan defines three “drought intensity levels” for the basin, which activate certain drought management actions.
Drought Level 1 occurs when one of the below conditions are met:
- Low basin inflow
- Low state line flow
- Low composite conservation storage in APC reservoirs.
Drought Levels 2 and 3—which indicate more severe drought conditions and bring additional drought management actions—occur when two or three of the above conditions are met, respectively.
