    Drought in the Pacific Northwest

    Drought and its impacts vary from region to region—due to differences in climate. The Pacific Northwest is an ecologically diverse region where water supplies are heavily reliant on snowpack, precipitation, and groundwater, as well as on highly managed rivers, like the Columbia River. Despite its soggy reputation, the region is primarily wet in the winter but dry in the summer, and has experienced multiple droughts in the early 21st century—impacting agriculture, water supply, hydropower, tourism and recreation, fisheries, and wildland fire regimes.

    Recently, in 2001, 2015, and beginning in 2020, virtually the entire region experienced significant drought. In 2015 historic levels of drought were experienced across western Washington and Oregon. Over the last several years, while the coastal regions experienced an unprecedented single-year drought, central and southern Oregon and Idaho suffered under a prolonged, multi-year drought.

    In response to drought in the region, NOAA’s National Integrated Drought Information System (NIDIS) launched the Pacific Northwest Drought Early Warning System (DEWS) in 2016, encompassing Idaho, Oregon, Washington, and western Montana. The Pacific Northwest DEWS is a network of regional and national partners that share information and coordinate actions to help communities in the region cope with drought.

    Reach out to Britt Parker, the Regional Drought Coordinator for this region, for more information, or sign up for the Pacific Northwest DEWS newsletter.

    Historical Drought Conditions in Idaho

    Drought is a normal climate pattern that has occurred in varying degrees of length, severity, and size throughout history. Below, you can look back at past drought conditions for Idaho according to 3 historical drought indices. The U.S. Drought Monitor is a weekly map that shows the location and intensity of drought across the country since 2000. The Standardized Precipitation Index (SPI) is a monthly depiction of drought based on precipitation (with data going back to 1895). And the paleoclimate data uses tree-ring reconstructions to estimate drought conditions before we had widespread instrumental records, going back to the year 0 for some parts of the U.S. View more historical conditions.

    The U.S. Drought Monitor (2000–present) depicts the location and intensity of drought across the country. Every Thursday, authors from NOAA, USDA, and the National Drought Mitigation Center produce a new map based on their assessments of the best available data and input from local observers. The map uses five categories: Abnormally Dry (D0), showing areas that may be going into or are coming out of drought, and four levels of drought (D1–D4). Learn more.
