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. Learn more.

This graph shows the year-to-date composite conservation storage (in acre-feet) for the ACF River Basin—that is, the combined storage of Lake Sidney Lanier, West Point Lake, and Walter F. George Lake—as well as forecast storage for the next 4 weeks (orange line). The U.S. Army Corps of Engineers (USACE) categorizes conservation storage into 5 action zones, which trigger drought operations in the ACF River Basin:
- Zones 1 and 2: Not classified as drought conditions; normal operations are in place.
- Zone 3: Drought contingency operations are triggered; hydropower is supported at a reduced level.
- Zone 4: Severe drought conditions exist; navigation is not supported; hydropower is likely to be generated only during concurrent use.
- Drought Zone: Emergency drought operations are triggered; hydropower will only be met as a result of meeting other project purposes.

Current and forecasted lake levels for U.S. Army Corps of Engineers (USACE) projects in and near the ACF River Basin. Except for Lake Seminole, 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 the 1-week forecast (measured in ft MSL, feet above mean sea level).

* 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 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. Learn more.
NASA’s Short-term Prediction Research and Transition Center – Land Information System (SPoRT-LIS) provides high-resolution (about 3-km) gridded soil moisture products in real time to support regional and local modeling and improve situational awareness. The 0–100 cm soil moisture percentile data has shown to be useful for drought monitoring. The near-surface (0–10 cm) layer responds quickly to heavy precipitation and rapidly drying events. In deeper layers, soil moisture evolves more slowly and has demonstrated greater utility overall for drought monitoring purposes since drought evolves typically on timescales of weeks to years. Learn more.
Developed by researchers at Ohio State University and the University of Illinois, this high-resolution gridded soil moisture map shows soil moisture percentiles at 20 cm depth, derived from merging in situ soil moisture data from a wide range of state and federal mesonets across the continental U.S. and interpolating these data into a 4 km grid. Data are updated daily with a 1-day delay due to differences in network report timing. Learn more

The Keetch-Byram Drought Index (KBDI) assesses the likelihood of wildfires becoming large and difficult to contain by representing the net effect of evapotranspiration and precipitation in producing cumulative moisture deficiency in deep duff and upper soil layers.
The KBDI attempts to measure the amount of precipitation necessary to return the soil to full field capacity. The index ranges from 0, the point of saturation (no moisture deficiency), to 800, the maximum dryness that is possible. The KBDI value indicates the amount of net rainfall (in hundredths of inches) required to reduce the index to zero, or saturation. Learn more.
The Coastal Salinity Index (CSI) is a long-term monitoring tool that characterizes relative changes in coastal salinity regimes for salinity gages with long periods of record. It was developed to characterize coastal drought, monitor changing salinity conditions, and improve understanding of the effects of changing salinities on fresh and saltwater ecosystems. The CSI uses the same classification scheme as the U.S. Drought Monitor for high saline (or drought) conditions and the inverse for wet conditions. This map shows salinity classifications over the past month. Learn more.

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. Learn more.
The Standardized Precipitation Index (SPI) is an index to characterize meteorological drought on a range of timescales, ranging from 1 to 72 months. The SPI is the number of standard deviations that observed cumulative precipitation deviates from the climatological average. NOAA's National Centers for Environmental Information produce the 9-month SPI values below on a monthly basis, going back to 1895. In the legend below, D0–D4 represent dry conditions and W0–W4 represent wet conditions. Learn more.
Tree-rings are used to extend the instrumental record of drought to over 2000 years. The Living Blended Drought Product (LBDP) is a recalibrated data series of June-July-August Palmer Modified Drought Index (PMDI) values in the lower 48 U.S. states. This dataset blends tree-ring reconstructions and instrumental data to estimate the average summer PMDI values, which extend over 2000 years in some parts of the U.S. In the legend below, D0–D4 represent dry conditions and W0–W4 represent wet conditions.
