What drought has meant in Oregon

The National Drought Mitigation Center's examples of impacts observed in Oregon at each level of drought, starting with this week's worst here.

D3 Extreme drought This week

  • Low oxygen and high river water temperatures are affecting fish
  • Planting is delayed
  • Pumping well water increases; wells are going dry; homeowners are trucking in potable water
  • Reservoirs and lakes are very low compared to normal; irrigation water is scarce
  • Waterfowl disease outbreaks increase
  • Wldfire activity is high

D0 Abnormally dry

  • Ski season is impacted

D1 Moderate drought

  • Some fields are left fallow
  • Water levels begin to decline; recreation and other uses impacted

D2 Severe drought

  • Fire risk increases
  • Marshes are drying up, little water is available for waterfowl and wildlife; bears are moving into urban areas
  • Pastures are brown; hay yields are down and prices are up; producers are selling cattle
  • River flows are low and tributaries are running dry; conservation efforts begin in irrigation districts

Burn bans and water restrictions

The Drought Monitor does not issue burn bans or water restrictions. Linn County's officials, the state forestry or fire agency, and local water utilities set them, often once drought reaches D2 or dry fuels raise the fire danger. Check the county's emergency management office or fire marshal for a ban in force, and the alerts page for red flag warnings and fire weather watches.

This week in the West

The Drought Monitor authors' narrative for the map of Sep 15, 2026, released Sep 17, 2026.

An area from southwestern Oregon to central Washington into northern Idaho and Montana received some welcome rainfall during the week. The rain resulted in regional improvements in drought conditions. One location that just missed out was in northwest Washington on the Canadian border, resulting in a drought degradation, where continued low streamflows were observed. There were also areas on the California-Nevada border and central Arizona with drought degradation that also received little-to-no rainfall. Extreme drought is shown over much of central Oregon, central Utah, southern Idaho down into northern Nevada, and small areas in northern Washington and southern Arizona. Exceptional drought continues in southern Idaho, northern Nevada, and northeastern Oregon.

Looking ahead

Over the next five days leading up to next Tuesday, above normal rainfall is forecast in south Florida as well as a large area in southern Wisconsin and Minnesota into eastern Iowa and northern Illinois. The latter area of forecasted rainfall continues to the east through central Michigan, the southern Great Lakes, Pennsylvania, New York, and much of central and southern New England. Other locations with rainfall in the forecast this week are in the Appalachian Mountains, the western Great Plains, and the Four Corners states. Unfortunately, most of Texas, Oklahoma, Arkansas, Louisiana, Mississippi, and Alabama are forecast to receive little rainfall. Dry conditions are also forecast in California, Nevada, and Washington. Much above normal temperatures are forecast to continue this week in the central and southern U.S.

The 6- to 10-day outlook (September 22-26, 2026) favors above normal temperatures continuing over nearly all of the continental United States. Areas most likely to be above normal are again the south into the southeast, plus the far north. Hawaii is also likely to be above normal. For precipitation, the Eastern Seaboard is likely to have above normal rainfall as is the Southwest. The central U.S. into the upper Midwest is likely to have below normal rainfall. Hawaii and Alaska are both likely to have above normal rain during this period.

What this means

The five categories the Drought Monitor draws, and how the map is made.

D0 Abnormally dry
Going into or coming out of drought.
D1 Moderate drought
Some damage to crops and pastures; water shortages developing.
D2 Severe drought
Crop or pasture losses likely; water restrictions imposed.
D3 Extreme drought
Major crop and pasture losses; widespread water shortages.
D4 Exceptional drought
Exceptional and widespread losses; water emergencies.

The US Drought Monitor is drawn every week by authors at the National Drought Mitigation Center, USDA and NOAA, who weigh rainfall, soil moisture, streamflow, groundwater, vegetation health and reports from local observers. Each map shows conditions through Tuesday morning and is released on Thursday. It shows where drought is and how bad it is; it does not forecast it. CPC's outlooks do that.
