Mean annual flow definition

Mean annual flow means the average flow of a river or stream (measured in cubic feet per second) from measurements taken throughout the year. If available, flow data for the previous 10 years should be used in determining mean annual flow.
Mean annual flow means the average of daily flows over a calendar year. "MGD" means million gallons per day.
Mean annual flow means the average flow of a river or stream (measured in cubic feet per second)
