What drought has meant in Idaho

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

D2 Severe drought This week

  • Grazing season is shortened, vegetation is sparse; crops are left unharvested; feedlots are not profitable
  • Hydroelectric power is down; irrigation water allotments are significantly curtailed
  • River levels are very low

D0 Abnormally dry

  • Irrigation demand is higher than normal
  • Ski areas open later, visitation is lower, snowpack is lower

D1 Moderate drought

  • Deer are scrawny; bird population suffers due to loss of food and habitat; trees are stressed
  • Dryland hay and grain crop yields are low; other crops and pasture are in poor condition
  • Fire risk is elevated, fires spread easily
  • Well levels decline; reservoir levels are low; water shortages occur; water conservation programs are in place

D3 Extreme drought

  • Dryland farms are left fallow; forage is limited; cattle herds are cut
  • Number of fires increase
  • Spring snowpack is very low

Burn bans and water restrictions

The Drought Monitor does not issue burn bans or water restrictions. Nez Perce 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 29, 2026, released Oct 1, 2026.

Outside of Arizona, New Mexico, and Colorado, which experienced deep and substantial drought-busting rainfall this past week, the western states generally had unchanging drought conditions. The Pacific Northwestern states of Washington and Oregon began experiencing the first of its fall rainy systems, helping to ease drought pressure across western Oregon, where drought was downgraded in a couple spots. Drought and dryness also improved in southwest Montana and northwest Wyoming this past week.

Looking ahead

Ongoing substantial rain was falling Tuesday morning at the onset of the new U.S. Drought Monitor week, from Arizona and New Mexico into the Central and High Plains. This excessive rainy system connected to Hurricane Polo is projected to continue eastward this week into the High Plains, Midwest, and South regions. The Weather Prediction Center has moderate threats for excessive rainfall from the Southwest into Texas, Oklahoma, northward into Nebraska and Iowa. Drought-busting rains may be possible across the South as this weather system evolves this week. Looking into the next week, the Climate Prediction Center’s 6–10-day outlook indicates that well-above average temperatures will shift into the western states, along with below normal precipitation chances. Meanwhile, above average precipitation chances are projected from southern Texas into the southeastern states, including Florida. Above average precipitation chances are also projected for southeastern Alaska, with near neutral rainfall forecasts for Hawaii.

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.
