The rate of the river flow is measured in cubic feet per second (cfs), which is the measure of the volume of water passing any given point in a river in one second. One cubic foot of water is about the size of a beachball. 

These levels are measured by the United States Geological Survey (USGS) along the course of the waterflow at different points, or subsections, along a marked line. A river will typically be measured approximately 25 to 30 times at regularly spaced locations. USGS gage locations may have the ability to measure river flows, gage height, and/or precipitation depending on the need for information in the particular area.
