The Missouri River is expected to drop below flood stage at all gauges from Yankton, South Dakota to St. Louis by the end of the week. Officials warned that saturated soils and levee damage could lead to renewed flooding in spring, and levee repairs alone will cost more than $1 billion.
Recovering river levels ease barge navigation constraints, but lost crops and damaged infrastructure reduce farm output and raise freight costs. Expectations of renewed spring flooding add weather risk to next year's corn and soybean supply.
