Corps forecasts near-normal Missouri River runoff in 2026

Key Takeaways:

• The Corps projects near-normal runoff for the Missouri River in 2026.
• Officials forecast 24.5 million acre-feet, representing 96% of the average.
• It is the Corps’ first monthly management update of the new year.
• These projections can guide local communities and stakeholders in water planning.
• The forecast underscores stable conditions for the Missouri River’s flow patterns.

Forecast Overview

In its inaugural monthly management update of the year, the U.S. Army Corps of Engineers announced a near-normal forecast for Missouri River runoff in 2026. Corps officials project a total runoff of approximately 24.5 million acre-feet, translating to 96% of the long-term average.

Near-Average Outlook

The 96% figure suggests that the river’s flow will likely align closely with typical historical levels. While not an exact science, these projections help local authorities and community planners prepare for water management in the coming months.

Significance of Early-Year Projections

Beginning-of-year forecasts provide one of the first glimpses into how the river might behave during the rest of the annual cycle. They help inform decisions related to flood control, irrigation planning, and broader environmental considerations along the river’s course.

Why It Matters

Accurate runoff estimates are crucial for ensuring that reservoirs and dams along the Missouri River are prepared for potential shifts in water flow. Communities that rely on the river for agriculture and daily water use also benefit from understanding these forecasts.

Looking Ahead

As 2026 unfolds, the Corps will continue updating its projections to account for changing weather and precipitation patterns. The near-average outlook offers a measured level of confidence for those who depend on the Missouri River, signaling stable water resources for the months ahead.
