From Gage to Page: A Look Into How USGS Helps You Know the Flow

Knowing the streamflow of a river is important for many. For example, irrigators need to know how the water can be allocated to fields, boaters need to know if the river is safe to float, and municipalities need to know how much supply will be at their intakes.

Creating the Rating Curve

The rating curve is a relation between stage (river level) and streamflow (discharge). Each stream channel is different and, because the stage-discharge relation is a function of the streambed material and geometry, each rating curve will be unique to that site and a particular period of time.

Shift-Adjusted Ratings

Stage-discharge relations (ratings) are usually developed from a graphical analysis of numerous discharge and stage measurements.

Each measurement is carefully made, and undergoes quality assurance review. ...
