Evidence and review: in-review; source report. Research candidate. The government page is archived and should be checked against the current operational program before promotion.

## AI’s role

Multi-model machine-learning river prediction.

## What is documented

Agency announced introduction of M4 to its forecast program.

## Limitations

Archived agency announcement.

Current operational status needs confirmation.

## Why follow this?

Seasonal runoff forecasts inform agricultural and water-management choices in the western United States. The agency announcement is not an independent estimate of downstream benefits.
