"Crest" means the highest the water level is expected to get. "Flood stage" is the water level where the river is over it's banks, hence "flooding". A river can crest below, at, or above it's flood stage. It can crest three inches above flood stage (innocuous) or fifteen feet above flood stage (a disaster). Or anywhere in between. Or below flood stage. Every river, every spring, is different.

∙ 13y agoA river "crests" at a particular place when the water level stops rising and begins to decline at that point. The crest of a river slowly moves downstream, somewhat like a very slow-moving wave. The crest occurs hours or even days later at locations downstream.
