Passby Flow• A passby flow is a prescribed quantity of flow thatmust be allowed to pass a prescribed pointdownstream from a water supply intake at any timeduring which a withdrawal is occurring. When thenatural flow is equal to, or less than, the prescribedpassby flow, no water may be withdrawn from thewater source, and the entire natural flow shall beallowed to pass the point of withdrawal. Natural flowin the stream channel below the point of withdrawalis maintained at the same level as may prevail above
