What happened

Some supportReported by 2 outlets

Runoff in the upper Missouri River Basin for 2026 is forecasted at 60% of average, or 15.4 million acre-feet, which could be the 11th lowest in the period of record, according to the U.S. Army Corps of Engineers. The U.S. Drought Monitor indicated that 80% of the basin is currently abnormally dry or in drought conditions. Drought conditions are expected to persist or expand in South Dakota, North Dakota, Nebraska, and Iowa by the end of October.

Why it matters

Some supportBrind's analysis of the reports

The low runoff and drought conditions are stressing the agricultural infrastructure of several states. While recent infrastructure funding has improved navigation structures, the river is currently experiencing a low-water year, which constrains commercial barge traffic. Furthermore, lower river flow and dry conditions are linked to reduced electricity generation from mainstem power plants.
