Drought in the Missouri River Basin

In Wyoming and across the Missouri River Basin (MRB), drought is a common climate event. Prolonged droughts in the 1930s and 1950s substantially affected water supplies, agriculture, energy, transportation of goods, and ecosystems. More recently, short-duration droughts wreaked havoc on the MRB. The intense 2012 summertime drought surprised the region, as flooding was expected to continue into a second year following the devastating floods of 2011. Flash drought in the U.S. Northern Plains and Canadian Prairies in 2017 resulted in $2.6 billion of agricultural losses alone. In 2020–2021, drought affected the same area and was a multi-billion-dollar event that had wide-reaching impacts on the region’s communities, ecosystems, water resources, and agricultural systems.

Partly in response to the floods of 2011 and then the extreme and rapidly evolving drought in 2012, NOAA’s National Integrated Drought Information System (NIDIS) launched the Missouri River Basin Drought Early Warning System (DEWS) in 2014. The Missouri River Basin DEWS is a network of regional and national partners that share information and coordinate actions to help communities in the region cope with drought. Wyoming is also part of the Intermountain West DEWS.

Reach out to Molly Woloszyn, the Acting Regional Drought Coordinator for this region, for more information, or sign up for the Missouri River Basin or Intermountain West DEWS newsletters.

Historical Drought Conditions in Wyoming

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 Wyoming 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. And the paleoclimate data uses tree-ring reconstructions to estimate drought conditions before we had widespread instrumental records. View more historical conditions.

U.S. Drought Monitor

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.
