As of the 13 October 2026 U.S. Drought Monitor map, 88.3% of Oregon was in drought (D1 or worse), with 20.2% in extreme or exceptional drought (D3–D4). The 24 reservoirs we track in Oregon were 12.9% full on their latest readings. 22 of 24 tracked reservoir sites sit inside the drought area, 18 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.

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.
