American Waterways Operators members heard National Weather Service forecasters explain how drought in 2022 and 2023 caused low flows and salt water intrusion near New Orleans.

The discussion is mostly a retrospective on past low-water episodes, and it offers little new information about near-term barge capacity or grain prices.
Not enough comparable past events yet for a historical read.

Moves of each commodity's benchmark from the last close before the event. Historical reads pool past events of the same kind; they describe what happened, not what will. Not investment advice.
