How much water does the Mississippi River discharge each second?

The Mississippi River has an estimated mean discharge rate of approximately 600,000 cubic feet (17,000 cubic metres) per second, which is the largest in North America.1

It is important to note that this figure represents a general mean; the river's actual discharge fluctuates significantly based on the state of its tributaries and seasonal conditions. For instance, measurements taken at Vicksburg, Mississippi, have recorded flows as low as 93,800 cubic feet (2,660 cubic metres) per second during low-water periods and as high as 2,060,000 cubic feet (58,330 cubic metres) per second during high-water stages.2
