As of the 27 October 2026 U.S. Drought Monitor map, 88.1% of Mississippi was in drought (D1 or worse), with 28.8% in extreme or exceptional drought (D3–D4). The 12 reservoirs we track in Mississippi were 42.3% full on their latest readings. 11 of 12 tracked reservoir sites sit inside the drought area, 11 of them in severe drought (D2) or worse.
The Drought Monitor maps where conditions are dry this week — rainfall, soil moisture, streamflow — not how much water is stored. Reservoir storage lags it by months, so a region can be in drought with full reservoirs, or out of drought with empty ones. Source: droughtmonitor.unl.edu. The U.S. Drought Monitor is jointly produced by the National Drought Mitigation Center at the University of Nebraska-Lincoln, the United States Department of Agriculture, the National Oceanic and Atmospheric Administration and the National Aeronautics and Space Administration.

Storage from official US gauges (USGS, USACE, Bureau of Reclamation, CDEC) and, in Texas, the Texas Water Development Board. Fill % uses design capacity from the National Inventory of Dams where available; Water Data for Texas lakes use that board's conservation capacity; a few sites without a match fall back to the 5-year maximum. "% of month avg" compares the current fill with the reservoir’s own average for this calendar month over its readings on record. D0–D4 is the U.S. Drought Monitor category of the ground at the reservoir’s coordinates on the latest weekly map — local conditions, not storage.
