afterbay
Water below dam
An afterbay is a reservoir or basin that receives water discharged from a hydroelectric plant, pumping station, or canal.
It serves as a holding area downstream from the main operation, regulating flow and allowing sediment to settle before water continues on its course.
The term contrasts with forebay, which holds water upstream before it enters the system.
